In zone1 is one room who has a schedule with 23 degree between 12 an 2 pm. And hot water is circulating valve not closed I think
Perhaps netatmo can say something.
Hi,
Could you please let us know the serial number of the Valve(s) of this room?

Brieuc,
for all valves but one the situation has improved dramatically. Thank you for that.

For my bathroom, the valve still does not close fully, I just touched the radiator and it is warm (not full-power but still heating) but no request for heat is needed and displayed in the app:

The radiator has the connecting terminals (hot/cold) at the bottom, thus the valve sits only about 15cm above the floor.

Netatmo station in the same room also measures temperature still quite differently:

I have customer-support case JUV-ZKYFX-016 open for this and granted access.

Let me know if you need anything more (eg. photo of the radiator) to track down the issue.


Thanks,
-Markus

7.12. system works as desired.
About overheating in Zone2: today was not a usual day because we had craftsman here and the window was open from about 2 pm and we had an issue with our boiler in the morning therefore the boiler was completely off from 8 am til 11:30 am for maintenance.
Tomorrow I report again.

But isn't the main thing, if the valve was open or telling the heating to come on?

The room in question may well go over the desired temp (eg: because the thermostat is under temp), but if the valve in the room is telling the boiler to come on, or allowing the valve to open when the rooms temp has been met, that's a problem!?

@neilf no heat request in zon2 and associated valves the whole day.
But heat requests from zone1 during the day. Conclusion the 2 valves in the thermostatroom in zone2 are not closing full. Overheating is the result. My zone2 is under investigation from Netatmo. I report each day my zone2 overheating to see if it’s getting better. I do no calibration just let the system work.
