Hi,
I’m sure I ran into something several ppl. faced with… after trying to fix some Sonoff related Zigbee error, my Sonoff dongle / Z2m is dead. I hope someone can suggest some easy solution and I don’t have to reset, re-pair all my devices (some sonoff minis behind dumb switches, so it would take days…)
I had some issue with zblmini and I’ve seen strange errors in the log, so I started searching for solutions. I’ve read about this ‘ember’ thing and changed the adapter to ember, z2m won’t start. Then I continued reading and found I have to upgrade the firmware too. First I upgraded to 7.3.x (w/o problem), then I found only 7.4.x would work. But now, it is not working with neither ezsp or ember and I always have messages like this in the log

HA recognises the adapter
config # ls /dev/serial/by-id/
usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20230324172249-if00
However z2m won’t start
This is what I tried so far
- changing back the config to ezsp
- turn off HA machine and move dongle to different USB port
Is there anything else I can try?
Thank you
