Do you have any idea how do I troubleshoot not booting Hass on RPI 4?
What I did is installing zigbee2mqtt addon and had connected CC2531. It was working terribly slow during install, so I disconnected USB stick and checked the logs in Supervisor.
It said 500 and timeout during dowloading image of zigbee2mqtt.
I tried to restart in General settings, but logs said: Timeout of restart request
After that I tried to restart via removing power supply, and since then not a single sign of life. Ping is not working, no UI of web page, nothing.
I don’t have microHdmi cable so I cannot see the screen.
Any ideas, please, so I won’t loose all configuration?
