Living room is warming up when tado is not asking for it
I have a living room heated with radiators with standard old trv's, but it's controlled by a tado smart thermostat.
At night, temperature is set to 16 degc so it should not be heating, but still the temperature in the living room is being regulating towards 20 degc.
You can clearly see tado is NOT requesting the boiler for heat. Also not from any other room. No heat is requested anywhere (also no hot water).
Still, living room heats up.
This thing is driving me crazy. I tried reinstalling the app, I've checked all connections, what can I still do to figure this out?
I'm using a setup with 4 independent tado radiator thermostats in different rooms, and one smart thermostat in the living room with a few radiators with old school trv's.
The radiator thermostats are not in separate zones.
Boiler is a Viessmann Vitodens 100.

Have you got another controller somewhere, is there a timer attached to the boiler or do you have any Alexa or HomeKit automations set up? That’s all I can think of.
Or is this a possibility? https://community.tado.com/en-gb/discussion/16112/app-schedule-settings-mismatch0 -
Hi Johnny,
Thanks for the response. There are in theory no other controllers and also all settings in tado are right.
However, it seems the issue lies with the boiler itself. It has become much colder now and temperatures are dropping much lower inside the house (during away mode), yesterday to 15degc. However, the boiler still starts up every once in a while, heating the house a bit, without heat demand from tado.
It seems there is thus no temperature regulation being done. The boiler just starts every once in a while by itself, for whatever the reason.
I also noticed other strange boiler behavior (not keeping the water temperature settings and so on).
I think I'll contact Viessmann to see if they know whats up...0 -

Outside possibility:
If your Viessmann has weather comp it will have frost protection, which keeps the flow temperature at 20c when outside temp is below 5c. That would fire the boiler periodically at the moment.
If no WC, then not that.0
