After installing Core Update 26.1.0,
the Homematic(IP) Local integration
no longer works.
Is this error already known?
For this reason, Core Update 26.1.0 will be skipped for the time being.
Best regards, Klaus
also had problems after upgrade with BTHOME devices - shelly BLU Door, HT, Motion. Door only worked when somebody closed the door, opening was detected as button press and not as open, till that time it was unavailable and got back to this state after 1-2 min. same i had with Motion sensor it wake up only when somebody entered the room, but did not tell detection, else it was unavailable and got also back to this state. The 3 of my 4 HT senors didn’t communicate anymore.
all devices sended data to the Shelly app but no longer to HA.
The only HT sensor which still worked was thatone i added in the end of november to HA.
The solution was to delete and readd the sensors to HA again.
I’m guessing you’re referring to the custom integration from HACS, since HA Core integrations only list the Homematic IP Cloud version.
If so, an issue has already been opened and closed Since HA 2026.1 no connection to openccu · Issue #2743 · SukramJ/aiohomematic · GitHub
