Can you explain what adapter you're using and attach the full debug log? The log you've attached cuts off the beginning that shows what adapter you're using, what firmware is running, and what protocol version is in use.

Apologies, just attached the full log. I'm running the latest dev version of HA Core (v8 something) with the bellows dependency overwritten to v0.45.3.

Which Zigbee adapter is this?

Which Zigbee adapter is this?

It's this WiseConn Zigbee/Z-wave controller

I think the Zigbee firmware on the adapter may have been compiled without NV3 support. We rely on the NV3 interface to allow for some settings on the stick to be rewritten (namely the EUI64 address of the adapter).

Try out #683. It may fix your immediate issue but if NV3 support is missing from the firmware, this is something the manufacturer should address.

The firmware building infrastructure and configuration for the ZBT-1 and the Yellow are fully open source (https://github.com/NabuCasa/silabs-firmware-builder) so you may have better luck building 7.5.0.0 yourself for the EFR32MG21.

I wasn't able to get this working, but using zigbee2mqtt solved my issue
