Need help with home assistant and wall thermostat

[Jeroen]

Hello,
i'm trying to get something to work in home assistant.

What I want to achieve is that when I turn on the thermostat (from homematic) a switch (which is configured in home assistant) is turned on to turn on the underfloor heating pump. And then off again when the temperature is reached.
I hope you understand what I mean.
I am currently using node-red in home assistant. But I can't find how to detect a change in the thermostat setting.

Any help is welcome.

Access Point or CCU3 ?

FYI in this Home Assistant Facebook Group are also many HomeMatic users

Hi Im not using Hone Assistant therefore can not say sth hopefully someone else - also I saw you posted it in the Facebook group. I would also recommend to add in your post that you are using a CCU3 and which device you mean e.g. HmIP-WTH2 - maybe they need the info.
