## Zigbee2MQTT Device Troubleshooting ##
If no device is found after running `ls -l /dev/serial/by-id` reboot the zigbee2mqtt lxc and try again.
Make sure Proxmox sees the device by running `ls -l /dev/serial/by-id` from the Proxmox web shell.
If Proxmox sees your device, you can try setting autodev by running the below script from the Proxmox web shell.
If all else fails, try this:
In the Proxmox web shell run (replace `105` with your lxc Id)
```
bash -c "$(wget -qLO - https://raw.githubusercontent.com/tteck/Proxmox/main/autodev.sh)" -s 100
nano /etc/pve/lxc/105.conf
```
:warning: change `100` to your LXC ID.
Note: The changes will apply after a reboot of the LXC
