I have the same problem as eswjm1981 on HassOS 1.13. i have got 4 thermostats in three rooms.. the two in the living room work just fine but when I change the temperature for the one in the office or in the bedroom the other one changes as well.. I really don’t know why.. i will try to reset the max cube and install it again maybe this helps but I’m pretty sure it has worked in the past.

Just to confirm: still exists on 0.91.3. Integration is unstable and in some cases, the multiple thermostats are being updated when the temperature of one of them is changed.

@BastianPoe think you could debug this?

[BastianPoe]

Has there been a recent firmware update of the cube?
