AFTER having tested the Sonoff zigbee 3 with some devices with ZHA, I updated the Sonoff Zigbee 3 in ubuntu, following Flashing the firmware via cc2538-bsl | Zigbee2MQTT
The firmware was old (2019) and I had issues with a Vimar Switch that was reported off when it was on…
After the flash everything seemed ok as following log
THEN I reinstalled the usb in the Raspi 4. and tried to delete and reinstall ZHA service…
It seemed to work (screenshot) … .at first BUT then…
The zigbee network does not work again 
… (screenshot, error logs)
HOW can I recover ?
Thanks in advance
