First I'll state the original situation:
- Home Assistant on a Raspberry Pi4B in a Docker, with permissions set for admin access.
- ThirdReality Zigbee USB C dongle connected to /dev/ttyUSB0.
- Mosquitto running on Raspberry Pi 4B to talk to MQTT in HA.
- After setting everything up, paired the device I have (Aqara water sensor), everything working.
The Pi4B was getting overwhelmed, so I put an Industrial NUC in, migrated the data across and ran Home Assistant's Docker setup on the new machine.
The ThirdReality at first wasn't showing up as a device, eventually I got it to after some "fun".
I did install Mosquitto on the new NUC and have it running and MQTT is connected to it.
No matter what I did, I couldn't get Zigbee2MQTT to talk to the device, so I read about possibly using ZHA. So I went the route of ZHA. It did see the dongle and connected, but it failed to create a new network during the setup process, so I had to repeat the process and go advanced. It is present, but I can't pair the water sensor with it as before. All attempts at resetting or making a new network error.
I read online about reflashing the dongle, but, if this is a software issue, that'll do nothing as the actual water sensor was paired to it before.
I looked at the forums and nothing there shined a light as to what to do to get this network issue resolved, so I'm hoping someone here can help.
