3rd party temperature sensor support or cheaper add-on temperature sensor

Mauritsss

I have multiple tado radiator thermostats, but all of them are a couple of degrees out with the actual temperature. I use an Aqara temperature sensor to measure the actual temperature in the room, further away from my radiator. It would be great if the tado app could use the data of these aqara sensors to measure the temperature.

I am aware of the add-on wirelesse temperature sensor Tado is offering, however these are ridiculous expensive, 90euro, compaired with the 15 euro's I have paid for the aqara temperature sensor.

I don't need a temperature sensor with a screen, I just want one that is as small and as cheap as possible.

So please launch a cheaper temperature sensor or make it possible for 3rd party temperature sensors to feed the data to the tado app.

Have you tried the temperature offset feature located in settings. You can adjust the temperature sensor in the radiator valve unit by the difference your room sensor is measuring. E.g. valve temp reading 20 degrees, room sensor you have is reading 18 degrees - reduce the offset feature by 2 degrees. This way you do not need to rely on a room sensor to control the temperature in the room and should compensate fir the difference in the room temperature and the valve temperature. Hope this helps

@PhilK yes I am aware of the offset feature, however the problem with the radiator thermostat is, it measure the temperature next to the radiator itself. When I turn on the heating, the radiator thermostat measures an increase in temperature within 15 minutes, however on the other side of the room, it is still the same temperature. Even with the offset feature, it won't improve a lot during the heating process, maybe one when there is a constant temperature for a while.

Have you had a look at a new system just released. It seems to do what you are wanting. It is a wireless temperature sensor that you can put anywhere in the room. It interfaces into the Tado system and makes adjustments to achieve actual temperature you set for the room.

@markiaindean does the Ambtitemp thing mean that the Tado system is no longer manageing the heat? It looks like it requires yet another app and account, plus giving access to the Tado account. Have you been using it?

Hi @Leebaz, Lets start with have we been using it. The answer is yes and it does work. The way it works is by using the Tado api to set the room temperature offset to ensure that the Tado TRV valve temperature measure matches the room temperature as measured by ambi. So the Tado system is still managing your heating system and you still set target temperature using get Tado app or valves. The only thing the ambi does is tell the Tado system what the room temperature offset is. Yes there is a ambi application. Its only use is for configuring the ambi or switching it on and off. With regards to your Tado access details. You do need to pass this information to the ambi during configuration.

If you're interested in buying an ambi, we have moved over to an Etsy store.

Thanks Mark,

I've gone down a wormhole wondering if I can set something up with Arduinos and so on, but I'm guessing that's what you've already done!

The offset feature is of limited use since the difference between the measured temperature and the room temperature varies hugely depending on how much heat is being output by the radiator.

I’ve come to the conclusion that separate room temperature sensors are pretty much essential.

I agree with the OP- Tado’s own temperature sensor is far too expensive for this purpose. The Ambitemp looks perfect but I’m wary of buying a 3rd party device since ongoing support seems less guaranteed.

Here is a solution which may or may not be practical, but might give food for thought.....

I've been a Tado V3 user for three years. I have experimented with various configurations in order to meet my needs and address any Tado shortcomings. This heating season all eight of my Tado SRTs are mounted loosely onto the valves. Thus each one can measure temperature and turn the boiler on, but none can close off the radiators. All radiators are balanced, but left open, so that all rooms receive heat whenever the boiler is on.

SRT temperatures Vs actual room temperatures actually work perfectly well in my home. But if I wanted temperatures measured elsewhere, such as the far side of the room, I could simply move the SRT for that room to wherever I wanted the temperature to be met. This avoids the additional cost of a separate wireless temperature sensor. The only downside, potentially, is the aesthetics of having an SRT somewhere in plain sight within the room.

Of course, my set up may be a bit extreme. An option might be to implement my solution only in the room(s) with the issue. Other rooms could continue with the SRTs shutting off radiators as necessary.
