Zigbee2Mqtt working but can't recognise new devices

[wizardofozzie]

I’ve had no problems running HA on Raspberry Pi 4 for the last ~1 year. Device = Sonoff Zigbee 3.0 Dongle-P (old version, not E)

Z2M began playing up around a month ago at version 1.35 or so. My zigbee devices are still connected and functioning, however, the Zigbee GU10 Tuya lights stopped working recently and despite being removed from the configuration.yaml and HA config, I can’t add the devices to Z2M again. I’ve tried reseting other devices which are currently paired/working, and reseting to repair does not get recognised.

TLDR: cannot get Zigbee2Mqtt to recognise new devices

Someone else is having a similar problem - don’t know if they’re connected:

Trouble adding more than 30 devices via Zigbee2MQTT

Hoping someone can give me some advice here. I’m running Home Assistant Green, with a Sonoff Dongle P via Z2M. I’m running into a problem where Z2M simply won’t adopt any device after around 30. 21 of those are Sengled lights, the other 9 are either Third Reality or IKEA Tradfri outlets. LQI on everything is 90+, and viewing the map shows that the lights are distributed fairly evenly through the routers, with only the outlets talking directly to the Sonoff Dongle coordinator. Attempting to ado…

Thanks for the link. doesn’t appear to be related. I’m going to update firmware and try again.

I want to flash the coordinator firmware, but the device won’t unscrew (I’ve tried for hours). I initially flashed the device with coordinator firmware using a python script either on mac or raspberry pi- can someone remind me the process? I’ve googled it and all reference seems to require me opening the dongle which was never required the first time
