2 Homematic-IP-Thermostats are always set together

[juergen.mnich (Jürgen Mnich)]

Hello!

A few days before I installed two newly bought Homematic IP Thermostats.First I added them to the raspberrymatic and the status and control via webui works fine (still).

Then I added them to openhab (2.4.0). There are other homematic things in my installation from before (even 1 other thermostat) and all of them work fine.

The problem with those two new things is, that I cant control them separately. If I change the temperature on one of those two, the other changes its setting as well (see log below)!!

Where did I make the mistake?

Regards, Jürgen.

Thing HmIP-eTRV-2 000A18A99426D7 …
Thing HmIP-eTRV-2 000A1A49A13771 …

Both your Things have the same UID. Only one will “win”.
Your Items are linked to the same Thing.

EDIT - okay I’ll take that back having read the docs. Homematic uses the serial part 000A18A99426D7 as the UID.

Still looks like they are cross-linked though, I wonder if a leftover from earlier edit/copy/paste.
Have you restarted the binding since last editing your Things and Items files?
Small in-flight edits can be missed by many bindings.

I can’t believe it. I would bet I tried a restart already, but… what should I say… a restart of the whole system solved the problem…
Thanks for your advice!!!
