Hi there I’m using zigbee2mqtt on HAOS in Proxmox but after installing zigbee2mqtt from add-on
zigbee2mqtt cannot start do to SRSP - SYS - ping after 6000ms error.
I try everything updating firmware on my sonoff zigbee usb dongle-e v2, making sure that ZHA is not using it, etc…
at the end i fixed by updating my dongle firmware to this version and adding
adapter: ember
after my port.
serial:
port: /dev/ttyACM0
adapter: ember
so i wanted to share this information maybe someone can find it helpful.
