Zigbee2MQTT 1.35 failed to start

The new version of Zigbee2MQTT (Z2M) adds new features and improvements, but occasionally, they can break compatibility with existing devices :).

If your PTVO-based devices do not work in the latest version (Z2M shows the “Unsupported” status for your device), it seems, you should update a custom converter for it.

Option #1

You can re-create a converter in the latest version of Firmware Configurator, update it in the “data” folder, and restart Z2M.

Option #2

Or, if you cannot remember a configuration of your old device, and therefore re-create a converter, you can edit the existing file:

1. Find your custom converter “.js” file in the “data” folder of your Z2M installation.
2. Replace the following lines at the beginning of that file.
3. Restart Z2M.
