Problem setting up StellaZ radiator valves

Configuration Z-Wave
1

Hi,
I am trying to migrate from domoticz on Raspberry to HA on Synology with docker. Installation has been tricky but solved. I am having problems with the many radiator valves (Eurotronic StellaZ) that I have and that I have been using with no major problems in domoticz. here is the issue:
I have included the device, and in the zwave configuration interface, for the corresponding node I set WAKE UP INTERVAL to 3600 (this in domoticz would tell the valve to check back to the controller every hour for getting new values). This value avoids draining the batteries with frequent reporting or polling by the controller.

Then I created a ‘radiator’ type card in the UI for the radiator Comfort setpoint (by default the valve uses this setpoint).

Here comes the problem: if I change the temp value from this interface (say from 18 to 21) the value stays for a few seconds, then changes back to the original (18). It seems the interface does not accept any new value.

Am I missing something simple since I’m new to HA?

P.S. All the above without mentioning that the ‘current temperature’ value shown in the interface is a possibly very old value but this is a separate issue solvable with frequent polling. There is a post on this)

Just to mention for anyone that may incur in the same problem that I found out that, despite the temperature setting done in Lovelace seems to be ignored (and goes back to the previous value if I refresh), if I leave it for some time, the new value is received by the TRV when it wakes up (or when I explicitly wake it up). Hence the whole thing works (with some exceptions … not so reliable). i guess the new generation of these TRVs would be more reliable.
