Does tado have an API ? Where can I find the documentation ?
Although we do have an API, at this time we do not provide any documentation or support for it.
At this time, the best documentation for the API can be found here:https://www.openhab.org/addons/bindings/tado/
Please feel free to discuss any question you might have about the API in this topic together with other community members.
It looks like the room (zone) temperature is read-only?
(My intention is to use the API to add small wireless temperature sensors to some rooms, where the human space is often very different than the TRV’s location.)
As commented before, we don't support the API.
However, what you intend can probably be achieved easily through some of the free official integrations, eg. IFTTT
You can use the offset setting in the app to compensate for this. Just measure temp difference in the “human space” and check difference to TRV. Adjust the offset in the app in rooms setting.
dennisoliver, I’ve only found this useful up to a point. Sometimes the valves get warm before the room and shut off, then cool and come back on, rather than staying on until the room is up to temp. Would be neat to be able to add a small sensor.
Obviously you can add more Tado wall thermostats, but they’re not cheap!
@jacoscar Can we hear more about this please?
I've had a play, and written some code that directly sends offset information from an ESP8266 to Tado, using a DHT22 as the temperature sensor.
It's not great code, but it does work. It's probably a bad idea to use more than one, in case they try and connect at the same time.
I intend to replace it with several feeding into Home Assistant, to reduce the number of API calls
ps, I hesitated to publish this, if you don't understand it, it's probably not for you ;-)
@jacoscar, would you mind showing me your script home assistant script? I am looking for a similar solution, where my Hue motion sensors, which are already in all the rooms, deliver the correct room temperature. I'm just not sure how to write a script that pulls the pulls the real temperature, calculates the required offset and then pushes it to the right room in Tado.
Btw, is @Jacopo also your user?
