Domoticz

Hi There,
I am just getting started with domoticz. I have included some switches and TRVs.
For testing reasons I bought a Danfoss and the much cheaper Eurotronics TRV. The Danfoss one works rather well.
The Eurotronic One on the other hand keeps working for about two hours. After that time Domoticz stops updating the readings and cannot communicate with the Valve anymore.

In The Control Panel however, the Valve keeps waking up at the desired times and I can even set the temperatures correctly.
Does any of you have an idea how I can correct this?

As it turns out it will report the correct Values Again after I hit the update Burron in the Edit Menu of the Thermostat. But it only works for about one hour. Is there a way to hit the button automatically every 30minutes?

I think they are the same as EUROtronic EUR_STELLAZ Wall Radiator Thermostat Valve Control
I also did not receive any updates, untill I told domoticz to poll them.
It is not logical, but now I have updates. I had also to use a wake up valvue off a multitude of 240.

Sadly this does not get rid of the issue.
The other valve also has the same problem. The Z Wave Control Panel shows the correct Values but Domoticz says it can't reach the node.
