Since this topic was kinda dead, I was in doubt of posting the solution I finally found but here goes.

First I tried all kind of things, for example altering the manufacturer_specific.xml file, excluding/reincluding the valve, setting the valve to factory settings, updating all kinds of libraries ...

Unfortunately it doesn't update its setpoint. Didn't know if the time-out had something to do with it.
I haven't checked in OZWCP if they are awake when I push the button, though the thermostat needs to be awake when I change the wakeup interval. SInce this works fine, I guess the wake up part works ...

300 sec, although I lowered this to 60 sec for testing purposes.
Since that didn't do the trick, I put both back to 300

Hi All,

Recently I purchased 2 POPP thermostats (kinda the same as the Danfoss LC-13, but with different firmware).
I included both thermostats and they are available in domoticz.
However when I try to alter the setpoint, domoticz gets a time-out
