I have encountered problems with zigbee on my homeassistant yellow, I installed the matter addon and after a while I uninstalled the matter addon. From that moment zha stopped working and when I try to configure zha (/dev/ttyAMA1 115200 hardware) its says “Failed to connect”. Sadly without an entry in the log file. When i am using an external CC2652R based USB-Stick zha works fine.
Trying to resolve the problem I flashed the firmware to latest EZSP version (v6.10.3) but stil I am unable to configure /dev/ttyAMA1 to ZHA. Any ideas how resolve this?
