I have a set of 10 Sonoff ZB-DS01 (door window sensor); 1 never worked even when new (unable to pair); after about 1 year of use some of them starte going offline; I’ve tried new batteries and moving the sensor closer to the bridge with no luck; I am able to remove the device and re add it and it would work for a few hours before going unavailable again
I’m using this bridge flashed with tasmota
