TRVs not turning off when reaching target
I have new Tado X TRVs installed with a central boiler. Temperature measured by TRV, no separate temperature units.
Recently i have noticed that some of the TRVs doesn't turn off when reaching target temperature. se picture.
-Batteries are new so that is not the issue. And more then one TRV is affected.
-The TRVs turns off and on perfectly according the schedule so the pins are not stuck, and the TRVs work.
-Manual changes or "turn off/on" through the app works immediately without any problem.
-The TRV show the same info as the app and the radiators are warm so its not a communication issue with the app.
-The bridge is less the 10 meters from the affected TRVs (dry walls only).
And Yes, I have remounted the TRVs.
Still, hitting target temperature they continue to heat, not turning off as they should.
Any ideas and help appreciated because I am confused ;-)

Could be many things. If these are upstairs rooms (so the rooms are also heated by downstairs) the rooms can overreach. It happens shortly after a major drop in outside temperatures and so the stats are pushing the boiler too hard. One option is to use the app to set a temperature offset to force the specific stat not to overreach (this option is available in V3, not sure about X - let us know).
