After upgrading to HA 2023.4 I get this repair warning.
OTBR and ZHA use the same radio but different channels.
If OTBR and ZHA share the radio, they must use the same network channel.
If OTBR and ZHA try to connect to networks on different channels, neither Thread/Matter nor Zigbee will work.
OTBR is configured with a Thread network on channel 25, ZHA is configured with a Zigbee network on channel 15.
You can check out “Resolve channel conflict” section in the link, you can either change your Zigbee channel to be same as Thread or the other way around. Make sure to pick a channel that’s with less interferences. About multiprotocol support – Home Assistant Yellow (home-assistant.io)
