Zigbee2MQTT SRSP - SYS - ping after 6000ms please help :(

Its hard to tell exactly what’s wrong from the logs.

Some suggestions to try and troubleshoot are:
1- Check that the addon is set to the correct serial port for your device
2- Check you have the mqtt mosquitto addon up and running, and configured properly

Additional setup info is here

If still not working, try to enable the advance debug mode and check for additional log entries:

Enabling zigbee debug mode

If you want to troubleshoot in more depth problems with your zigbee devics, sometimes you must enable DEBUG option on Zigbee2mqtt startup. To do this you must set zigbee_herdsman_debug to true.

zigbee_herdsman_debug: true

Based on this line, one other thought is that there is an old incompatible config that the program is finding and trying to restore. You may want to temporarily move that file somewhere else and try and start fresh.

I use zigbee2mqtt in docker so don’t use the addon version, so hopefully if this doesn’t work someone who is more familiar can provide some more info.
