Loxone: the formula to a real smart home

So what exactly is a ‘Smart Home’?

Is it a house that has a doorbell camera that can record potential intruders?

Or is it as house that has a big ‘Beware of the dog’ sign on the front gate, when the home owner doesn’t have a dog?

The answer, is of course, these are both ‘smart’ things to do, they both might put off intruders, and yes, the latter is undoubtedly the cheapest and easiest to deploy! They are however both technically static standalone ‘security features’.

Just because something is smart to do, it doesn’t mean that it is ‘smart’ by nature. Static features are not able to automatically and dynamically react to changing situations.

The term ‘Smart Home’ is being so increasingly used and abused I am even loathed to using it myself. But that’s a shame. In a bid to try to wrestle the definition back from serial misuse, I thought I would have a go at making my own distinction.

Real smart does real feel

At the heart of a real smart home is not necessarily just a skip load of widgets, functions and features, but interoperability and automation. The power of automation is completely dependent how features, functions and data can interact together in such a way that they can then change how systems work in real time. Dig right down into what makes automation possible, and you will find that everything is basically running on… logic and maths.

So the ability to be able to ‘program’ with the building blocks of logic and maths is a crucial feature of a real smart home system.

I am not a mathematician, I am just someone that understands a little bit about logic. I only just scraped a C at GCSE maths. However, despite this, I recently embarked on a mini project in which I used a little maths, some logic, and my Loxone miniserver to take data from two essentially ‘dumb’ devices and used this to create ‘smart data’ out for my home. My old Maths teacher Mr Baxter would be proud, though I never did forgive him for writing in my school report that..

Sometimes I wonder if Jones is still breathing..

So anyway the project….

Having turned distinctly chilly & windy as of late, I was looking at where the data from the house anemometer (wind meter) and outside temperature gauge displays on the house control iPad, and it struck me that I didn’t have any display data for ‘real feel’ or ‘wind chill’ temperature. I have temperature. I have wind speed. Surely then ‘wind chill’ (some combination of the two) would be simple to work out? Hmm!

A ‘Quite Interesting’ little formula!

After a little Googling I became a tad despondent. There are many online wind chill calculators out there, but I wanted to use my Loxone Miniserver to make my own calculations, with my own weather station data. For that I needed a formula. When I got it, I next thing I needed to figure out, was what on earth to do with it!

It turns out, the formula for Wind Chill (Celcius & KM/h) is this:

(Where T is the air temperature in degrees Celsius, and V is the wind speed in kilometres per hour)

My first thought was that this formula looked like something out of QI. With confidence in my own abilities, and personal experience that with Loxone it’s generally a case of not ‘if’ something is possible, but ‘how’, I got stuck in.

Maths warm up: M/S to KM/H

The first little problem is that this formula required ‘v’ in KM/H, however my weather station is giving me wind speeds in meters per second.

The first (easy) part is simply to use a couple of Loxone maths block to convert the wind speed coming off the weather station from m/s to km/h. Very straight forward case of multiplication and division.

(Above: super simplistic meters per second to kilometres per hour converter)

Where there’s a will there’s a chill!

Maths not being my best subject the next bit (main formula) was somewhat of a challenge for me. I stuck to my trusted problem-solving methodology, which is to break a problem (in this case, a formula) down into smaller parts and deal with it that way.

I basically tackled the equation in sections, multiplying the contents of the brackets, feeding in my temperature and wind speed adjusted to km/h. Then the very handy formula block enabled me to work out the wind speed to the power of 0.16 part.

Running the configuration in simulation mode (using static constant hard coded values for wind speed and temperatures) I could see that program worked, because I was able to compare the programs output with online wind chill calculators. However, after hooking it up to my live temperature and wind sensor data, out came some totally crazy temperatures.

I soon discovered, much to my dismay, that for this formula at least, wind chill cannot be calculated for wind speeds of 1.2 m/s or less. My dinky wind chill program would therefore splurt out completely spurious figures whenever there was little not no wind. Not good!

State block to the rescue here, and I was able to bolt on a little extra routine that essentially overrode the wind chill temperature value when the wind speed dropped to 1.2m/s or less. Under this condition, the text ‘NO WIND’ is sent to the readout instead of the spurious ‘feels like’ value. Victory is mine!


(Above: the wind chill formula transposed to a Loxone program with output suppression for no wind)

Wrap up!

In the grand scheme of things, yes this was a relatively simple formula based program to create, yes it’s not particularly ‘sexy’ and it just scratches the surface of the sort of complex programs and routines you can create with the Loxone system.

But it struck me that it’s really a rather perfect demonstration of impressive programmability that the Loxone system has its core, and the visual programming system (Loxone Config) which enables ‘visual thinkers’ like me to actually build and ‘see’ the program working (and almost as important, not working!).

The point of this post? It’s not about any formula in particular, but rather the fact that you can put formulas into Loxone it in the first place. This, in my view, is the acid test a real Smart Home.

So if you happen to be looking at a Smart Home solution, just ask yourself, does it pass the magic Smart Home formula test, which is: Can it actually run a formula?!?

If the answer is no, then I suspect the solution you end up with might be a bit smart

It just won’t be real smart.

Smart FIR project

Smart FIR: A Loxone controlled Far Infrared heating project

ACC HAUS have teamed up with leading UK Far Infrared heating panel provider Herschel Infrared to publish an example, fully costed plan to retro fit a one-bedroom apartment with fully automated / remote controllable FIR solution.

Introducing…. our apartment to be ‘smarted’

Our sample apartment is based on a real plan for a real project we worked on last year, and one we think is a great representation of a typical one-bed flat. We’re going to use this apartment as our template and gradually add functionality to it so you can see exactly what’s required to successfully complete this project. Of course, every property is different but we can use this plan as a working base and build it up / adjust it from here to find the perfect solution for your requirements.

Much of the pricing on this blog, is based on publicly available list pricing and is correct at the time of writing. Please get in touch for the very latest pricing, and be aware that we are continually running special offers and promotions.

First plan

A while ago we wrote a comprehensive and informative blog post about the trials and tribulations of converting a 1920s property from mains gas to FIR. If you have a little spare time and you would like an insight of a real-life FIR upgrade project – warts and all, we would strongly recommend you head over to this post for a quick read first. But if you’re a little pushed for time, lets kick off with a quick list of the pros and cons of far infra-red heating:

Far Infrared Heating – Pros and Cons


  • Excellent ‘quality’ of heat
  • Not convective therefore good for allergy suffers (less dust/pollen in air circulation)
  • Solid state, and therefore extremely low maintenance
  • Relatively quick and easy to install compared to ‘wet’ heating
  • Easier to move after initial install compared to gas central heating
  • Fitted to ceiling – does not take up wall space
  • Highly efficient (no heat ‘lost’ through pipes, pumps, or heating of air)
  • Ability to enable per room thermostatic control, managed centrally
  • Possible to power completely with zero emission renewable (solar / wind etc)
  • Highly responsive (short warm-up time)


  • More expensive to power / KWh than gas if using mains
  • Homes generally set at a cooler temperature which some may not like
  • Large amount of ‘scepticism’ in market for consumers not familiar with technology
  • More planning / calculations of heat loss / building characteristics required before purchase
  • No advantage for EPC assessment (classified as electric heaters for rdSAP vs full SAP)
  • For multiple panel systems, separate rings and therefore electrician required
  • Many questionable vendors on the market with dubious quality standards & no track record
  • Although easier to install than wet systems, if you are mounting panels on walls or ceilings there may still need quite a bit of re-decorating to do

For the right panels, select a quality vendor

We could write a whole blog on the purchasing and planning of FIR (well actually we sort of did) but the main take away is that if you are considering FIR heating, you MUST find a good FIR panel vendor. A good vendor will guide you through the process of sizing your panels, placing them, the purchase costs and hopefully estimate running costs. For reason covered on our FIR conversion blog, we have teamed up with Herschel Infrared in the UK so we would recommend getting in touch with them.

To make this project realistic, we supplied our project requirements to Herschel Infrared just like a typical customer would and this is the plan they came back with:Flat with panels

Running costs

To calculate the running costs, Herschel made some general assumptions of building fabric:

Cavity brick, 50mm roof insulation, two outside walls, 4m2 basic double glazed windows, timber frame ceiling and un-insulated concrete floor.

Total combined load: 2.38 KW

Program averages: On average of 5 hours a day for spring / autumn, moving to 8 hours per day in mid winter (plus baring in mind each room will have it’s own schedule – bedroom will not be on at all during day time)

Estimated running costs over a 238 day heating season: £375 

Likely annual maintenance costs: zero

Is a smart home controlled FIR solution the right choice for you?

We now know what sort of FIR panels we need, where we are going to put them, and how much (or little!) this solution is going to cost to run.. but hang on there just one minute. Before we continue and build our ‘Smart FIR’ solution it’s probably a sensible idea for us to be a little objective here and look at the pros and cons of going with a ‘Smart FIR’ solution vs the standard wireless controller systems which FIR panel vendors like Herschel typically supply:

If you would would like:

  • Real time control & monitoring of FIR solution via internet connected devices
  • Fully automated controls and intelligent ability perform advanced co-ordinate operation with weather forecasting data
  • Ability  to limit your FIR usage to a fixed usage / budget, or to notify you at certain usage levels / conditions
  • The solution to provide a fully extendable ‘smart home’ platform for other functionalities
  • And finally, you are OK to pay a little more for this additional functionality….

We would say, go down the Smart FIR route.

If on the other hand you just want:

  • A comparatively low-tech system which operates with ‘closed’ physical thermostats on the wall that give you the room temperature on a display.
  • Manual ‘boost’ buttons to switch on individual panels for short periods
  • You are not interested in remote control / monitoring or any automation outside that of operating the FIR panels
  • You do not want to have to control the system via phone / PC / tablet
  • Have no interest in other smart home functionality
  • You are on an extremely tight budget

Then we think the ‘traditional’ thermostat route is the better option for you.

(Note – it is still possible to get wall-based controls / readouts with the Smart FIR solution, but this would add cost, and additional wiring too )

So a good use case for a Smart FIR solution would be a home, a second home, or perhaps someone caring for an elderly relative where the carer wants to keep an eye on the heating remotely plus wants all the benefits of a very low maintenance FIR solution.

Alternatively, a good use case for traditional FIR controlled solution might be a landlord wanting a low maintenance solution for budget rental accommodation. In this case there could be a high turnover of tenants all of which may want to access the heating system to adjust. Providing a fixed, wall mounted tablet would solve this, but costs money – but might need servicing, updating and could also get broken.

If you think the Smart FIR solution is right for you – let’s get started!

Where to start? At GO – of course!

Miniserver Go

Loxone MiniServer Go: £341.22 Inc. VAT

At the heart of every smart home solution, is a smart home server, and here at ACC HAUS we have for a long time been avid fans of Loxone solution for ‘real smart’ homes.

To try to break down exactly what a Loxone smart home server is (without boring you too much) we are basically talking about a highly programmable ‘solid state’ device which enables you to feed in ‘input’ data, whether that be a temperature from a sensor, or a button push, and then using this input data (with pretty much limitless programmability) apply some logic to then perform any number of outputs, again whether that be turn something on, move something, or even create another input to do something completely different. Everything that is programmed into the system, whether it is a movement sensor,  a doorbell, or Far Infrared panel for that matter, can seamlessly inter-operate together. So, you can build some highly integrated solutions, and the limit really is your (or our!) own programming capability and imagination!

Loxone make two models of smart home server. One is called simply ‘MiniServer’ and the other is ‘MiniServer Go’. The ‘MiniServer’ product, because it has many built in physical connectors for both inputs and outputs – is generally preferred for completely new projects or major renovations where there is a lot of re-wiring going on. For the ‘retro fit’ there is generally no desire to run a lot of new cabling and perform the all the decorating work to make good. Therefore, for these sorts of projects you would aim to go wireless and use a MiniServer Go.

It is still possible, with additional modules to extend the MiniServer Go exactly as the MiniServer, and they both run exactly the same software.

When talking about the MiniServer Go, a common concern we get from homeowners and trades people alike, is worries about wireless performance. This is taken from negative experiences with WiFi wireless networking (we’ve all had them) – however the sort of wireless technology used in Loxone systems is completely different and is far more robust, secure, and extendable that the wireless networking you get on phones and pcs. It’s running a living space and having lived with it myself for the last three years, I would go as far saying it’s completely bulletproof, because it has to be.

Yes, you do still need to consider range, wall thickness etc, but unlike your typical wifi it is extremely simple to extend coverage of a Loxone wireless network. Last year we supplied a completely wireless solution to a circa 1890s four story house in France. Huge solid walls, but with correctly sited equipment, this 100% wireless solution has been 100% reliable from the basement wine cellar to the wireless weather station placed right on the top of the roof. There’s a write up on that project here.


For smaller properties, there will likely be no issue with distance / wireless coverage, so your main factor is going to be getting your MiniServer Go connected to your home network and a power supply. The obvious place to site the MiniServer Go therefore is next to your home router – it doesn’t take up much space.

Our second plan of the apartment now shows the position of the MiniServer Go, close to the Internet router, on the other side of the TV:

With miniserver Go


The basic initial configuration of the Loxone MiniServer Go is not difficult but, if purchased though ACC HAUS – we pre-configure everything before we send out. All that is needed to be done is to simply plug it in. To get external access, there is a small amount of work needed on your home router (port forwarding) – we can help with this via a remote session.

Remember though, if you change Internet providers, or if your internet provider changes your router – we will need to repeat this work for you to get remote access.

No internet? No problem!

One of the best things about the Loxone system, unlike pretty much every other smart home system out there now, is that with Loxone, you do not need any Internet connection at all for the entire system to function. Yes, you need it for remote access or external notifications (email / phone calls etc) – but if your Internet was to go down, the system would continue to function completely as normal.

Additionally, because the solution is not ‘cloud dependant’ you will also be pleased to know that none of your smart home data (programs, usage – anything) is sent outside of the server to any external party or their ‘partners’, and so you can rest assured not to be getting coincidentally suspicious emails from people selling air conditioners if the temperature in your lounge goes up in the summer!

Loxone Smart Socket Air (UK plug type G): £65.15 Inc. VAT each

Smart Socket Air

Behold, the mighty Loxone Smart Socket Air, the first device we are going to add to our Smart FIR setup, and what a marvellous invention it is! The Loxone Smart Socket Air can be ordered with sockets for many different countries, in this case we are in the UK so we have the good old three pin plug.

The Smart Socket Air gives you the following sensors which we can hook into using Loxones free smart home configuration software ‘Loxone Config’

  • Online Status
  • Temperature Sensor
  • Power used
  • Energy used

Then we have the outputs we can control:

  • LED actuator (small light on plug)
  • 13 Amp Relay (so we can turn on / off power to the socket

For this project, we are going to be using Power Used, LED and the Relay. For three rooms, we are going to opt to use dedicated Loxone Temperature & Humidity Sensor Air sensors, rather than rely on the temperature sensor built in to the Loxone Smart Socket Air – the reason for this is that we get more flexibility with regards to the thermostats placement. By using a wireless sensor, you can place it at the perfect height (usually light switch height), and if it’s not quite right, it’s easy to move. The Smart Sockets need mains power, so there is no easy way to move these later, plus you are likely not to want to see a smart socket air exposed anywhere.

For the hall, we are going to be OK to use a Smart Socket Air temperature sensor here.


You are probably not going to want to see your Smart Sockets, they are not exactly pretty to look at, plus they ‘click’ a bit as the relays switch on and off – as most relays do.Therefore, we would recommend, to get your electrician to create a dedicated ring/circuit for your FIR panels, and then create multi socket bay out of the way somewhere. The FIR panel power lines all run back to this point, connect to Smart Socket Air plugs, which are fed from the consumer unit. For this single bed apartment project, we have a total of four Smart Socket Airs:

  • Lounge (2 x panels on the one plug)
  • Hall
  • Bathroom
  • Bedroom

There’s no doubt about it, the work required to put your FIR panel cabling up to the ceilings of each room (and generally placed centrally too) and run the lines back to your Smart Plugs – is by far the trickiest part of this project. If you are lucky enough to have loft space or a suspended ceiling where you are converting, then of course it’s much easier, but if not, you are either going to have to live with conduit, chasing into walls / ceilings, route behind coving, or even considering lowering the entire ceiling with battens / plasterboard. The thought of doing this might make you grimace but if we consider what we would need to do for a wet radiator system (or underfloor heating even) that would be considerable more work.

If your apartment is already electric heated, but using expensive and unmanageable storage heaters, then you will already have electric points for these heaters going to each room, likely also on their own ring. In this case, you would still need to get your power line to the ceiling, but at least there would be much work saved in getting the power lines back to your consumer unit / Smart Socket Airs.

We have now added the Loxone Smart Socket airs to our ‘Smart Plug Bay’ in the hallway of our apartment, which is fed by a dedicated power line to the consumer unit:

Flat with Smart Socket Air

Loxone Temperature & Humidity Sensor Air: £77.56 Inc. VAT each

Temperature and humidity sensor

We have four open spaces to heat, in the old days we would just have one thermostat for the entire property, but because we want maximum control and efficiency (and why not!) we will opt to put our thermostats in each space we are heating.

The Loxone Temperature Sensor Air is powered by two every day and easy to source  ‘AAA’ type batteries and will last for at least two years before changing. Another great feature of the Loxone wireless system is the built in battery management, which can alert you when devices batteries are running down and need replacing – ether on the app, by email, or even by phone call (requires Loxone Caller service).

Temperature readings from this sensor will get fed directly into the MiniServer Go and once in here, our program will then enable us to determine whether our FIR panels should be switched on or off.

In addition to temperature, this sensor also has two internal ‘digital input’s which can be used to connect Loxones very inexpensive digital door / window catch sensor. We will use these in our project to tell the Miniserver Go that if there is a window open in a room, we can then switch off the heating (no point heating a room when the windows open).  Being a fully integrated smart home system, we can also use this door/window catch sensor as a dual purpose – to function as an intruder log and alarm. Although this project does not include the specification for an audible alarm, the MiniServer Go can still send us a popup notification alarm to our phone or email you if a window is opened when we have set the house alarm. At any time, you will be able to check the ‘access log’ – something especially handy to view front door usage to check (or be notified) if someone has left / arrived at home.

The wired digital window/door contact is cheap, but the downside is that as it’s wired and connected to your temperature sensor, this does somewhat limit your ability to move the temperature sensor later. For ultimate flexibility, with the same result, you could always consider a Loxone wireless door/window sensor instead.

We think the best solution in our case, is to use wireless temperature sensors for lounge, bathroom and bedroom, and run wired window contacts from these. For the hall we are going to use a temperature sensor on a Smart Socket in the plug bay, and then a wireless door contact for the front  door. This works out slightly cheaper than using 4 x wireless temperature sensors, plus with very frequent use of the front door, the battery on the wireless temperature sensor / wired door contact would run down faster.

This is a great illustration of how flexible a Loxone based smart home solution is – giving us cumulative smart home benefits other than simply just heating management, whilst allowing us ultimate flexibility to use the best placed device sensor to reduce costs.


Thermostat placement for FIR systems needs a little thought in order to get a representative ‘feels like’ temperature. Putting your temperature sensor too close to your panel will give you a higher temperature reading and cause the panel to switch off prematurely. Conversely, placing the sensor too far away from the panel, will result in a lower reading and therefore you panel will be running longer than it needs too. This will likely need a little experimenting with, but as these are wireless sensors, moving them around to find your heating ‘sweet spot’ is easy.

Although not needed for this project as it’s for a small apartment, for larger areas it’s quite straight forward to ‘connect’ the data from multiple wireless temperature sensors together, output an average from this, and then use this average to control FIR panels across the entire space.

We have now added the three Temperature sensor airs & window / door contacts plus wireless door contact to our apartment plan:

Temp sensors added

Loxone Motion Sensor Air: £93.07 Inc VAT

The Loxone Motion Sensor Air

It may seem a little strange, in a heating project, to chuck in a motion sensor, but, they do make sense (at least one of them) to help us get an indication that there is someone at home for the heating to be on. Yes we could manually set the home to ‘away’ before we went off on our holidays, but that’s not complete automation. What if you forget? Perhaps your home router decides to give up the ghost? You’d be heating a flat perhaps for weeks when you didn’t need to. With just a single well-placed motion sensor, we can easily determine if there’s someone home and if not for a certain duration, put the heating into ‘frost protection’ mode automatically.

Like with the Window / Door contact sensor, the motion sensor air also makes for a great mini burglar alarm.

The Motion Sensor air is powered by 2 X AA batteries, and like the temperature sensor air, should last a good two years without need for replacement.


For what we need to know (is someone home) lets put this somewhere very central like the end of the hall by the bathroom / bedroom door, near the lounge. Just stick on the ceiling with no more nails tape – job done!

Here’s our updated plan with the single motion sensor added:

Plan with motion sensor

Loxone Weather Service (1 year):  £55.84 Inc. VAT

Loxone Weather Service

It’s a common request for the placement of external temperature sensors, but most of the time, for consumers that simply want to gain a basic outside air temperature, we think investing in an external weather proof sensor is probably a bit overkill. Most external sensors need to be hard wired and weather proof, to the cost of fitting and integrating this into a typical project like ours is comparatively high. If you really need to do this, then the Loxone Weather Station Air is a fantastic bit of kit. It is easy to site outside, is completely weatherproof and being wireless, it’s easy to hook up with the MiniServer Go – however it’s a little pricey at £446.69 inc VAT. So we think a better bet for a ‘local’ weather reading is to use Loxones own Weather service which will enable your MiniServer Go to what the temperature is in your local area. A bonus with the Loxone Weather Service, is that it will enable you to feed in weather forecast data too.

This ability to ‘forward look’ means that – imagine you are away skiing and your smart home, being in ‘away mode’ is not heating because it’s placed itself in frost protection mode. With the weather service, your MiniServer Go would be able to spot rapid / dramatic temperature changes in the forecast, such as ‘the beast from the east’ and be ‘ready’ for it when it hits by automatically ‘over heating’ to prepare for faster heat loss with the dramatic drop in outside temperature.

Switch on!

You bought and had your panels fitted, plugged in your Loxone kit, so now it’s time for switch on!

Rather than turning a manual thermostat on the hallway wall at home, now you can completely control your FIR panel system through your phone, tablet or PC. It’s at this point that we would talk through several heating regimes with you to match your personal preferences, but in the most cases, setting heating to ‘automatic’ and then set temperatures for different heating modes (comfort, party, frost protection, cosy) and the system will take care of everything for you.

On the matter of heating schedules – here’s an interesting point to consider. Remember that unlike traditional heating system which take a while to get up to temperature (pumping hot water to rads around the house) – heat delivery from FIR is pretty much instantaneous. If your existing radiators have to switch on at 6am in order to warm your room by 7am  – that’s a  big chunk of heating time, most of which can be avoided with a FIR system. You will feel warmth almost immediately, and so FIR would come on much sooner, so perhaps 6.45am.

A key differentiation of using Loxone to heat your house is that on the ‘automatic’ program, the system is constantly monitoring and ‘learning’ how long it’s taking to get each room up to the target temperature. So if you want your bedroom to be 20c at 7am, your Loxone miniserver may start your bedroom panel at 6.45am one day, or deeper into winter, maybe it starts up at 6.30am. So the time taken to reach room temperature is remembered and ‘on times’ are automatically adjusted, every single day and completely automatically. The key benefit of this technology of course is that your rooms will always be the precise temperature at the time required, plus you will never need to heat your rooms for a minute longer than is actually needed.

We can design heating systems with FIR for virtually any requirement. One such requirement we designed – SLAM (Sequential Loop Active Membership) enables you to only run a single panel of a number in a sequence at a time, with panel joining and leaving the sequence dynamically depending on target temperatures. With our SLAM heating mode you never use more power than a single FIR panel on a ‘string’ at any one time. This is handy for capping max power draw around larger spaces where there is a fixed limit of power budget available for heating.

Monitoring and budgeting

With the perfect heating regime in place, and full control over it, you can now relax; in fully automatic mode, you might never need to change your heating settings. The house will automatically stop heating rooms if windows are opened and will also automatically place the house into frost protection mode when you’re are away, whether you have remembered to tell it or not.

But there is more to a FIR smart heating system than controlling it – you will most likely want to check on how it’s performing too.

With our Loxone FIR solution, for each room you can see a graphical output of live and historic temperatures, and the amount of power used by that rooms FIR panel. With a little extra Loxone programming we can combine the energy use of multiple FIR panels together, giving you not only per room graphs of energy use, but also whole house too.

Loxone: The smartest foundation for your home

With the project done, adding further functionality to it, additional sensors, or perhaps lighting, home audio, intercoms – all of which integrate, are things you may want to consider in the future. All the work in the initial MiniServer Go setup is done so adding to your existing system is going to involve much less work.

Project Costs

We wanted to focus this project completely on FIR, in order to simplify the process, technology and costings of the solution. If your requirement is simply to upgrade heating, and not a major refurbishment, then the mostly wireless approach on this project will be the cleanest, quickest and overall cheapest (at this scale) means to complete it. If there is scope to perform some wiring, and perhaps add in other smart aspects such as lighting or audio, our equipment selection could be adjusted to further reduce hardware costs.

For example, if lighting was required, temperature sensors would be included in the light switches. A ‘One Wire’ module plus wired temperature sensors would be cheaper than 3 x wireless temperature sensors. A relay module could control up to 16 FIR panels, and would be cheaper than purchasing 7 Smart Socket Airs. Obviously wired devices need wires, and complete re-wires are messy and expensive in their own right.

Every house / requirement is different so naturally we would always ask you to get in touch so we can find the optimal solution, at the most economical price for your needs.

Same brand equipment avoids same old problems

Earlier this month we kicked off our campaign for ‘Smart Networking’ in the Smart Home, a subject extremely close to our hearts, thanks to our vast experience working in the Enterprise IT sector.

In our introductory post, “Why Smart Homes Need Smart Networks”, we made the point that generally Smart Home ‘core habitation services’ such as, lighting & heating and sensing, have always been simple to deploy, reliable and relatively management free. This is only possible because such services run on closed, tightly vendor-specified control networks.

Devices such as CCTV, video entertainment systems and multi room audio, on the other hand, are required to be situated on the home network, so well outside the comparative safety of the Smart Home’s closed control network. It’s a real risk, then, that your ‘home network’ becomes your Smart Home’s ‘out of control network’.

To prevent this, Smart Home networks must therefore operate just like control networks do. They must be tightly specified, configured, managed and completely secure – that’s the only way to guarantee reliable and safe Smart Home operations.

In our first post, “Smart Home networking fact 1”, we made the simple point that, although it is not necessary to ‘be’ an IT manager to create a Smart Home, you would end up with a much better network (and therefore a much better Smart Home), if you could adopt an IT Manager type of mindset.

For Smart Home Networking fact 2, it is in this mindset that we remain, as the topic of this post is an absolute IT classic, and one we have found sadly missing from many Smart Home Networking installations we have been invited to work on; standardisation.

Now we’d go as far to wager that you’d be extremely hard pressed to find a good IT Manager that would admit to spending any time ‘thinking’ about standardisation. It is such common practice to choose in-common equipment to prevent all too common problems – handing over a copy of Windows 10 to install from pallet load of 2, 778, 3.5” floppy disks… would probably be LESS offensive than asking an IT Manager whether or not he/she had at any time considered standardising on network equipment.


Smart Homes need a network that works, not a ‘notwork’ that doesn’t

It should be obvious then, that if you build a Smart Home network on a bric-o-brac of budget brand equipment, it will most likely succumb to the laws of the lowest common denominator. Or to put it another way, a home network will only ever be as smart as the dumbest network device you place on it.

Standardising on network equipment is the textbook first move from the IT pro’s playbook because doing so vastly improves manageability, monitorability and ease of configuration. These are the building blocks which allow us to create the ultimate ‘Pineapple Network’ – hard and unforgiving on the outside (secure), sweetness and sunshine on the inside (reliable & capable). In networking terms, you only need ‘one a day’ and that’s a Pineapple.

So, we have established that smarter networks are standardised networks. Now, what to standardise with?

At ACC HAUS we’ve done the in-depth research for you and we’d like to recommend Allied Telesis as your preferred Smart Home networking equipment vendor.

Allied Telesis are the perfect fit for Smart Home networking, because in our view, they are the only networking vendor that offers the ‘holy trinity’ of reliability, capability and security, at a fraction of the price of other well-known, high specification Enterprise brands like Cisco. Unlike many network equipment vendors, Allied Telesis also have a huge advantage, in that their product range offers a fully integrated network solution that includes next generation firewalling, switching and wireless devices. In the clear majority of cases, their products also share a same common operating system, called AlliedWare™ Plus.

We must encourage you to go far beyond simply standardising the brand of product. To get maximum impact from standardisation, we not only want  to better control how devices work as individuals, ideally we want to control how these devices work together. So standardisation better enables integration, and it is integration that is the key to achieving true network automation, a mandatory characteristic of a ‘Smart Network’.

We’ll be covering exactly this topic, integration, in our next post for Smart Home Networking Fact 3!

Jeff says:

“Selecting a single network equipment vendor will make it a lot easier for you to build yourself a ‘Pineapple Network’ for your Smart Home. We sell many different brands, but for Smart Homes we only recommend Allied Telesis. Standardising on Allied Telesis products enables us to deliver secure and sweet Smart Home firewalling, switching and wireless functionalities, enabling us to give our Smart Home customers, the smarter networks they deserve.”
