Hi all,
I just ordered one of the Zigbee Heiman Smoke Detectors on AliExpress.
Binding it to the ConBee stick works easy, but the sensor is not visible in the Phoscon App.
However the discovery in Pimatic works and the device shows up with three parameters:
- no fire / fire detected
- online
- batterie status
The test for the alarm works.
The ‘online’ status seems not to work, as it doesn’t change by pulling out the battery.
The batterie status seems also to work. But I’m not amused about is the fact, that the delivered battery right from the beginning on was on 45% and after some testing now is on 14% 
This battery will definitely not live 10 years …
