I tried both things that you suggested with initially not apparent results
- I have replaced the power supply with an Apple iPad charger (5V2.1A)
- Recovered homey, even though it seem that with the current procedure there is no way to select “full software update” as described here
Eventually and very late, I was able to add one of the Sonoff sensors as generic Zigbee device via one of the extender. One more curious thing is that despite that, it is seen by the system as connected via the Sonoff App
I will do more tests today.
