strange. configuration looks good,
do you see multiple thermostats in home app? if you change one does it change all others as well?
from homekit binding perspective there is no way to connect thermostats to a group or so.
i assume, you have not defined any rules on thermostats changes and the items are connected to different things…
if you change one thermostat directly via openhab UI and not via homekit, does it also applies to all or only to one?
Yes I’m seeing all four thermostats and if I change one it changes all (except one…???)
I’ve not set any rules.
It also changes all (the three that change) when I change it with Google Home (which worked fine before)…
And yes if I change it inside openhab directly it also changes the other ones.
One strange thing here is: Mode is changes and matches all, but the set temp is off…
Temp change at Thermostat#1 to 24°C, mode switches to “ON”
All thermostat modes switch to “ON” and temp changes, but not to 24°C but to something higher (maybe last value they had when they where “ON”?)
Changing the Mode from Thermostat#X all modes match again and if the mode has a fix temp stored, the temp matches the stored value.
