This add-on acts as a proxy to an external running Zigbee2MQTT instance. The sole purpose of this add-on is to add a Zigbee2MQTT icon to the sidebar of Home Assistant which will open the frontend of an external running Zigbee2MQTT instance.
server(required): this should be the local URL on which the Zigbee2MQTT frontend is running, e.g.http://192.168.2.43:8080. Make sure there is no trailing slash!auth_token(optional): only use when you have anauth_tokenset for the frontend in the Zigbee2MQTT configuration.
