Pros and cons

According to our thermostat expert
  • You can control and read the temperature via an app on your smartphone and on the radiator knob.
  • To save energy, you can set up time schedules for each day of the week.
  • With an Auto Assist subscription of € 3.99 per month, this thermostat has functions like geofencing and open window detection to make it extra energy-efficient.
  • This expansion only works combined with a Tado starter pack.
  • Without a bridge, you can't control the smart radiator knobs via the app.
  • You can only install this smart radiator thermostat on your heating if you already have a thermostatic radiator knob, which you can recognize by the numbers 1 to 5.

Description

The smart smart radiator thermostat from Tado doesn't work with all radiator valve brands. Check in advance which brand thermostat knob you have. The radiator knob from Tado is suitable for valves from Caleffi, Comap, Danfoss, Giacomini, Herz, Olymp, Siemens, and Terrier.

These 4 Tado radiator thermostats allow you to decide the temperature in every room. Install the Tado app on your smartphone and tablet to adjust the temperature per radiator. Make sure that you have the Tado Bridge. Without the bridge, you can't adjust the radiator knobs via the app. Is no one home, or is a window still open? Receive a notification via the Tado app. This way, the heating is never on unnecessarily. You do need a subscription for these extra functions.

saves energy and can be changed on the go, very handy

  • the radiotor of each room can be controlled separately
  • so if each radiator has its own TADO, you can, for example, only heat the office while the living room remains at 18 degrees: very handy

Tado is a handy thermostat for temperature control. What most reviews don't tell you is that since the end of 2018 you need a subscription to unlock some smart functions. The features you don't have without a subscription are geofencing and open-window detection. The subscription currently costs €25 per year.

Tado requires a subscription if you want to use the smart functions that distinguish it from normal thermostats. I think it's a shame, especially in this day and age, to withhold energy-saving features.

Beautifully smart system, but still needs improvement.

  • Very smooth installation
  • Strong technical support
  • Beautifully designed
  • No possibility to create your own schedules

For many years I was a very satisfied user of Honeywell Evohome, a similar smart system to individually heat zones in your home. I eventually switched to TADO because of the many positive reviews and the fact that it is compatible with Apple's Homekit (Evohome is not). However, I had no idea that TADO did not allow to set different heating schedules. Even a general ON or OFF function is not provided. The system does use 'Geofencing', which means that it knows when everyone has left the house and so automatically turns off the heating (and turns it back on when you get home)... erm... if you pay 3 euros a month for it to activate this automatic service. You can also do it for free, but then you will receive system messages on your smartphone to which you have to respond if you want to effectively switch the heating off or on.

For people who work irregularly, like me, it is very cumbersome to set different times for each room every day.
In addition, you cannot copy time blocks to other rooms or certain days of the week. So you have to go through the entire procedure again for each room. That is much easier with Honeywell Evohome! It is very strange that TADO does not learn from this. It doesn't look like they have any plans in that direction either, because on the user forum that question comes up very often without feedback from TADO.
But if your family leads a 'normal' rhythmic life, I can highly recommend TADO. The system works well and reliably. The installation runs very smoothly thanks to a sophisticated online guidance system with very detailed descriptions per boiler type. If you still can't figure it out, the excellent technical support is there quickly. I can safely say that there are few companies that provide such strong support as TADO.
So I am cautiously positive, but I strongly hope that they will allow more switching schemes in the near future.
