My issue is that the Sonoff RF Bridge is linked ok. But the Smoke Detectors shows the status "Off". (Which is seen at Next Hub.) A picture from the App is seen as a screenshot that is attached.
This is the smoke detector modell: https://www.aliexpress.com/item/32991306616.html
We tried it multiple times with smoke but no reaction at all. Not sure what the issue is...
Anyone knows how to fix this?
