Homematic IP works with temperature sensors but not with keyfob KRCK

Configuration
1

Hi,
I have successfully running homematic IP, which gets the data from my raspimatic. I use the temperature sensors from raspimatic for my floor heating. Everything works since over a year. I was looking for a keyfob remote, to use it as a switch for different thinks, and found HmIP-KRCK

I adapted it to raspimatic, and there every keypress works, as seen here:

But in developer tools in HomeAssistant the relevant data is not updated:

SCR-20251113-jcnw
SCR-20251113-jcnw2376×1526 292 KB

any idea what else I have to do? I cannot remember that anything “special” needed to be done for the floor heating.

thank you
Juergen

I found that I have to activate the buttons like here described

but get an error:

After the call I went to the CCU (raspimatic) and than devices → krck I than could transfer something, and since than the keys work.

If I see it correct, you have to activate each key. I first hat only three keys running, because I (for what ever reasons) I tried
developer tools -> actions homematicip_local.create_central_links
three times, and acknowleded all in the CCU.

But this might be a wild guess from me. Fact is: I only had key 1-3 than I retried the above command in developer tools in HA and acknowleded it in the CCU and than I had 4 keys.
