A couple of years ago, I reviewed one of the first generation of smart thermostats on the market in the UK. Long before Nest was available, the German made Tado was making significant inroads into our fledgling IoT marketplace.
Two years have now passed and Tado have released v2 incorporating an upgraded Smart Thermostat and an Extension kit for dual zone control. In my opinion this is sorely needed so I have big hopes that it works as well as intended.
Before continuing to review this upgrade, we need to look at a some statistics from the 2 years the 1st generation system has been in my property.
Straight energy saving comparisons between Tado v1 and the traditional method of heating that was pre-installed in my property (the legacy thermostat) are actually difficult to quantify for a number of reasons. We cannot compare money spent as we have fluctuations in energy prices which would cause us some calculation issues. Secondly, the weather. Of course this is being tested in Britain, weather changes all the time, so one year could have been considerably hotter or colder than the next so please keep this in consideration.
KW/h expressed in units are what are reported but for the purposes of this review I will refer to them only as units. I took an average of the three years prior to my time with Tado (with the same energy provider) and compared the result to the units used each of the two years with the device.
Here are my results;
Year 1: 21% less units used
Year 2: 26% less units used
As you can see, under my conditions, using Tado has saved a significant amount annually which would have easily paid for the price of the 1st Gen model in the first year.
The bottom line is that Tado deliver on their promise.
Now that’s out of the way, let’s move on to the new upgraded version.

I opted for a professional to install it for me, firstly as I did not want to mess around with my heating system but more importantly I wanted to see how Tado handle the entire upgrade.
As the equipment arrived with instructions on how to install, my first thought was that Tado had got a little mixed up as the instructions advised me to register the device before booking my installation which sounded a little odd as I already had a Tado system in the house.
But I should have had more faith in Tado because my new devices were registered and a professional installation were booked in an instant by following the instructions.
I will say that I think that Tado could improve on their communication with their upgrade customers, specifically that the proper procedure is to register new devices first which will eventually allow you to book an engineer install further along in the process.
Each step felt like it was leading up to a manual setup which I did not want.
Secondly they could just advise the user that your old setup will run alongside the new one until the professional fits the devices which does become apparent at the end of the process.
But with all that said, Tado continue to impress me with not only the devices but the way they make setup so easy to follow. You may have a nagging feeling that the setup process will eventually lead you down the wrong path but if you stick with it, you will have no problems. Tado know what they’re doing and I could name a few tech companies who could take a lesson or two from these guys.
The only thing that seemed to cause the engineer some trouble was pairing each device.
I think this was more due to the engineer’s lack of knowledge rather than Tado’s design as one call to Tado themselves and it was fixed remotely in a matter of minutes.
If you can take anything from this review – call the Tado support team if you have any problems – the service really is second to none.
Anyway, back to the devices. The first generation Tado thermostat has been replaced with a similarly looking white plain thin box. When discussing the aesthetics with my wife, she hit the nail on the head when she said “the box just disappears into the wall, you wouldn’t even notice it day to day” and that is exactly what a thermostat should be. Clever but invisible.
But don’t be fooled by the boring exterior, one press of the front button and the device wakes to show the temperature set in a very cool white LED. Each press flips to a new display showing the current mode:
Heating Status (On or Off)
Hot water setting (if you have configured the system for this)
The next two pages show the conditions. Two touch sensitive led little arrows allow you to change the settings on each page.
Tado has been set up in my property to control two zones and my hot water tank. I can control each zone independently from the device or my iPhone.
Above is the photo of the first page showing the main temperature in that room and of course below the set point temperature which is where the heating will come on if the room temp drops to that level. You can see at the bottom the fact that Tado tracks where it’s users are, which in my opinion is the best thing about this system. It is simply brilliant that the system knows when I am just round the corner and may need the heating ready for when I get back as the room temp is below the set point temp, but equally if we are 20 miles away at work, the system knows not to do this as it will take at least an hour to get home.
Equally zone 2 also operates in the same manner and can be set independently from zone 1 which is downstairs for us. The system allows you to set times when the system will operate, so for example in zone 2 we only need it to work in the evening as we normally go up there to relax and watch TV. But because of the timing feature, if we were home during the day this zone would not be heated as it was outside of the time range we had set. This is all very versatile and will fit around any family household but again is all very easily over-ridden by going manual on the app or simply clicking the button on the thermostat which with a few finger presses lets you override.
Tado are a very interesting company and have already signed up to Apple’s HomeKit. The eagle-eyed amongst you would have noticed the Tado logo in the HomeKit presentation in Apple’s WWDC earlier this week which means that not only are the company working with the whole HomeKit which will become available in Autumn 2016, but it should also allow the device to be able to work alongside the other brands that were also on screen in the pic below.
Apple HomeKit Brands
Imagine what this means for a moment, if Tado get this right you will be able to have the device interact with brands that are nothing to do with Tado themselves. For example temperature spikes as it is in Manual Mode in error – flash my Philips Hue lights red to notify me. Or even better, use Tado’s geo-fencing properties to know when I am coming home to ensure heating is on (Tado), lights downstairs are on and ready (Philips Hue) and the garage door is now open (Fibaro Z-Wave Sensors). This will be subject to the Extension Kit being upgraded by Tado as I have been informed this will not be a simple software upgrade as the Extension Kit came out before Apple’s certification process.
On top of this Tado support have told me that the devices themselves also have some unused sensors inside which they may use at some point in the future. This intrigues me as it shows they are future proofing themselves. They have also now signed up to IFTTT, the popular website which again connects devices.
We are looking forward to testing the individual radiator controls as this is the logical next step to total heating management in the modern home allowing you to control individual radiator temperatures per room, but these are due Q3 2016.
To conclude, Tado is a no-brainer for me, if you haven’t got one, then start looking into it as it should quite rapidly save you money in an area which seems to be getting more and more expensive.
The system is solid, with even more solid support to go with it. It will fade into your wall as you forget it is even there and I think this is exactly what it is designed to do.
