Hi everyone, I’m struggling with my Bticino Living Now relays. Periodically, some devices drop off the network and become “Unavailable” for no apparent reason.
My Setup:
- Sonoff Zigbee 3.0 USB Dongle Plus with the latest Z-Stack firmware.
- Connected via USB extension cable to avoid interference.
- Zigbee Channel 20.
- Home Assistant with Zigbee2MQTT.
When a relay disconnects, there is no way to bring it back online easily. Power cycling the main breaker doesn’t work; the device remains invisible. The only solution is a physical hard reset, which is a nightmare because it requires removing wall plates or opening junction boxes.
The strangest part is that if I take one of these “offline” devices and try to pair it with the official Bticino/Legrand Gateway, it is recognized instantly. This confirms the relay’s radio is fine, but it somehow “refuses” to rejoin the Sonoff coordinator after a dropout unless a full factory reset is performed.
Has anyone dealt with Bticino/Legrand Zigbee stack? Any tips on how to force a rejoin?
