I’ve flashed my sonoff zigbee bridge following instruction here:
I’ve added it to HA and paired with devices. After around two days all devices became unavailable. I’ve re-added them, but after another one or two days I lost them again and now bridge is not visible by HA. Any ideas? I’m using firmware 9.0.2. When I was using original firmware, it was stable and was working for few weeks without any issues.
