Tado Smart Thermostat review: cell thermostat

Smart thermostats begin gradually come on the market. The Tado Smart Thermostat is after the second nest has reached our test lab. We have our home thermostat replaced by Tado and went with them to work.

In short the Tado (by the company itself, incidentally written as Tado °) Smart Thermostat thermostat that you hang and where you then no longer need to watch for. The basic principle is seemingly simple: the thermostat is connected to the GPS signal from your smartphone. If you’re at home, the heat is on and once you step outside the door, the boiler will stop heating your radiators. This is potentially very useful, since the majority of the Dutch population always has a smartphone in their pocket. Note that the Tado is still a traditional thermostat in the sense that it only regulates the temperature in the room where you hang him. No division into several zones or areas so.

In this article we discuss how the Tado Smart Thermostat has been there during our test from. Since we are dealing with a product that is aimed at a market where a lot of variation in (including in the field of thermostats and boilers), it is not said that in particular, the installation of the product equally simple or very complicated.

Before we discuss the actual product, first a fact about the name of the device. The name ‘Tado’ is composed of two Japanese greetings, as Tado’s website tells us: “tadaima ‘and’ Okaeri. These greetings mean “I’m home” and “Welcome home.”

Parts and acquisition costs

The Tado Smart Thermostat consists of up to three components: the thermostat itself, a bridge for connecting to your home network and an optional Extension Kit, which includes the Extension Box. The latter need you now if you do not have a thermostat or if you currently have a wireless thermostat in your home. You connect Extension Kit than with a cable to your boiler. We have the Smart Thermostat tested in a house with a wired thermostat, so the Extension Kit, we did not need. The thermostat is battery powered, and the Extension Box. The bridge must be plugged into an outlet.

The standard configuration of thermostat and bridge costs 249 euros. For the complete set, so including the Extension Kit, you lose 348 euros. You can also choose to rent. It costs 6.99 euros and 9.98 respectively per month. The latter is done in case you want to try it first. Even if you rent and are not sure whether you can or can take the thermostat to your next home can be useful. However, it is not that you can put on a month say you’re a contract year.

When you do the installation yourself, then these are all costs. Have you not so much confidence that you can do it, or is your specific situation so complex that it is not wise to do it yourself (something happens reportedly occasionally), it is still not possible at this time an installation engineer to order via Tado. That would from the beginning of the next heating season (Autumn 2015) have to be the case.


You install the Tado Smart Thermostat through tado.com/login where you step by step through the installation process. The first thing you should do is the bridge to your router or switch link. Bear in mind here is that you put the bridge out of sight: the bright white LEDs on the bridge are in fact unnecessary fierce. Then put the batteries in the thermostat and replace your current one. Turn you do this for a while your boiler off. Do not have or wireless thermostat, then place your after hanging the Tado the Extension Box near your boiler. The connection between the two is made wireless, as well as the connection with the bridge. These compounds is established through the 800 MHz band (868 MHz to be exact), therefore, have a relatively large range.

The scope of delivery is tasty complete, so including screws and dowels. There’s even a screwdriver in the box. In our case the Tado could be precisely located at the same location as the old thermostat. We could also use the already existing holes, so it was in our installation done. The formats of the Tado is also all along. It is a square box of about 15 by 15 inches and is just a few inches thick.

During the installation process you have to enter the type of thermostat and boiler you have (in our case a Honeywell Chronotherm IV and Vaillant hrSOLIDE VHR-C) and an installation guide is generated based thereon. When we installed the thermostat a few months ago, the manual for our situation was not yet available. You can not continue the installation and get the message that there especially for you a manual is made and that you have received within one day. That is really neat. With us beat the final manual alone at all, which is a pity. You must of course provide this information for you disconnect your existing thermostat, otherwise you would be without heating or the thermostat for nothing have disconnected.

The Tado is compatible with virtually all heating with own boiler, both modular and on / off control and can also handle the OpenTherm protocol. Use your boiler a proprietary protocol (like many Nefit boilers that instance), then you would do well to inquire as to Tado what about the support this.

The app and GPS

The final part of the installation procedure of the Tado Smart Thermostat you will be prompted to download the Tado Heating App. Only this allows you to make optimal use of the thermostat. He is only available for Android and iOS. This does not mean that you can operate the thermostat only from Android and iOS devices. You can operate it because from any device with a browser and Internet connection remotely from your personal page on my.tado.com.

What you miss when you are not using the app, is what makes the Tado special, namely linking the app with the GPS signal from your smartphone. Based on the location of the thermostat determines how hot it must be in your house. In his own words Tado used GPS data only in real time to determine where you are and it does not include the data.

That app is at first sight not overly complicated and extensive. That’s a good thing, because controlling your heating should certainly not be complicated. There are actually only two screens, one main and a settings screen. The main screen consists of three panels. On the top are notifications of the thermostat on the middle of the current temperature, set temperature and whether you are at home, in bed or on the lower road and you see where you are relative to your home. The Tado namely makes use of geofencing. He adjusts the temperature so on the basis of location. The two lower panels can be swept to the left, then added something to see additional information, including the savings you’ve achieved thus far that day.

The main screen can assume three different colors. Yellow when you’re home and the thermostat is in the “daytime” blue when you’re home and it is in ‘night mode’ and green when it is clearly based on your GPS location that you’re not home. In most examples, see attached, only one smartphone, but you can link the Android and iOS smartphones of all family members to the thermostat.

The thermostat does a lot of work, but you have to still make some basic settings. You do that by from the main screen to swipe from left to right. You give that display a schedule and a night and day temperature. You can set the schedule by day, but also divided into weekdays and weekends or throughout the week to keep the same schedule. Keep in mind that the thermostat will keep the room where he depends on temperature is around the time that you set as a ‘wake-up’. You go and any housemates immediately after that time away for the rest of the day, then it does not make much sense. Furthermore, you can enable here if you want to use the GPS functionality of the thermostat and you can enter what you were heating costs during a certain period.

An important institution that we have not yet mentioned is Comfort Level. If you put high on the comfort, the room where the thermostat already all depends on temperature at the time you have set. You put the slider to the left, that is less and less the case. With this course, you save more. The slider imagine indirectly holds the temperature in Tado that if you’re not home. This temperature he further states automatically, but he loves so do take with this setting.

In addition to the settings that you do yourself, and perhaps occasionally adjusts depending on your experience, Tado Smart Thermostat is partly self-learning. Geofencing is a good example. Then it is not so much that he realizes that you are gone, because that just goes through the app and GPS. However, in their own words, the thermostat will also learn how to heat based on your location can be as efficient as possible. He does this on the basis of how the previous times has gone, and based on how far you are away from home.

The thermostat is also linked to the weather forecast. According to the Tado website he uses weather forecasts to save energy and prevent your house too hot. If it’s a sunny day, it makes the sun partially keep the maintenance of the temperature and so could otherwise be fired. He uses the weather sometimes for giving helpful tips. We saw in the morning when we woke up once were alone that we would do well to take an umbrella because it was raining.

Not every home is the same, both in structure and heating system. Every house must be heated so as a private firing pattern. On the basis of how quickly loses its heat a building, it is possible to learn such a heating pattern. That Tado Smart Thermostat doing so also according to the makers. In practice this means that in poorly insulated, often older houses is often more convenient to pretty aggressive firing while in well-insulated homes is just more efficient to keep the temperature structurally higher.

If you just do not want to use or you can create all the hip and automatic learning tricks of Tado, you can control him of course just manually, using the app, website or the thermostat itself. To do the latter, you’re busy on the physical button until you reach the temperature, after which you can adjust the temperature by means of capacitive buttons.


We are Tado Smart Thermostat now several months to use and there are generally pretty good about speaking. It is very convenient to have a thermostat that automatically turns on when you get home and goes out when you leave the house. You forget, in any case never to turn off the heating. You do not have to necessarily take into account a pre-set schedule. Do you use a more traditional thermostat you can create schedules already, then you sometimes forget that schemes to adjust when something changes, making your house occasionally for nothing is heated. When Tado the app and the GPS signal from your smartphone is more important than the schedule that you set. If you’re not there and there is a well planned schedule, the heating will not start.

About saving aspects of Tado (in their own words about 30 percent), we can at this moment actually still not very much of substance to say. That will be reflected in the annual settlement and of course also depends how much should be fired anyway. During our test, it is our not yet really noticed that the Tado is different for heating. The house we have tested it dates back to 1928 and is no star in retaining its heat. In such cases, preferable is a relatively aggressive firing pattern generally. That is, it is generally better to firmly lit to heat the home relatively quickly and the temperature is thus quite lower at times when you’re not home. Trying to keep the temperature constant higher amounts to “lighting the sparrows’, because heat keeps the house still not fixed.

From the beginning the Tado has applied such an aggressive firing pattern, so at that point there was not much to learn for the thermostat. If you have the ‘Comfort settings’ not quite turn direction as comfortable as possible, however the Tado exaggerates sometimes our opinion somewhat. He leaves to keep the temperature regularly drop to 13 degrees. If this temperature is never reached, that in itself is not a problem, because then you know at least certain that the boiler does not start. However, it also results sometimes in a house where it really is 13 degrees and so stone cold to the touch when you get home. In such cases, it is simply impossible to get the temperature still at a comfortable 20 degrees for the time to go to bed. So we are forced to regularly for some time we go home to put the thermostat manually and enter a temperature. There seems, however, the thermostat is not really something to learn from, something that just would come in handy.

Geofencing what works varies. We have experienced situations where we twice in succession opened the app, a few hundred meters apart, with extremely varying results. Where we first sat in the outer ring, we were the second time in the inner.


The Tado Smart Thermostat is in our opinion an interesting smart thermostat if you have little to worry about heating your home (-room) want. If you are looking for a thermostat that keeps the temperature in all corners of your home at the desired temperature, the Tado is not the device for you. This is really a replacement for your current thermostat, which mostly does the same, only smarter. Would you like to be able to control the temperature in multiple rooms, you will find yourself at a (much more expensive) system as Honeywell evohome. Be the Tado best compared Nest, but then something smarter. Where Nest learns by analyzing how you adjust the temperature, Tado also takes you out of your hands. However nest offers you some more “edge cases” as extras such Nest Protect and Dropcam. Tado in the thermostat at the moment everything the company has on offer.

The Tado Smart Thermostat performs generally quite good, but the learning aspect is in our opinion not very well developed. The house simply cools down, making it impossible to get the right temperature. However, what we here like to mention explicitly, is that during testing for several months, not once has happened that we could not connect to the thermostat. Thus, it is in any case a very stable system. In our case, the installation of the thermostat was very simple, but that can vary case by case. Especially if you have the Extension Box itself still must close on your resume, it is said to be more complicated.

Based on our testing, we must conclude that the Tado Smart Thermostat not quite deliver what it promises. However, a GPS-based thermostat is very convenient. Whether it actually will result in savings, we can not say with certainty at this time. It is, finally, a solution for a single chamber. For more smart room heater you should still be elsewhere.

The price is still not low, with 249 euros for the basic kit of thermostat and bridge. Need the Extension Kit, you lose 348 euros. Rent costs respectively 6.99 euros and 9.98 euros per month.
