A simple daemon that monitors the availability of Zigbee2MQTT devices and sends a list of unavailable devices to an OpenHAB string item.
The configured OpenHAB string item will be populated with a list of device names separated by commas and a space (e.g. "device1, device2, device3").
- Enable the "availability" feature of Zigbee2MQTT
- Create a String-type OpenHAB item to which the offline device list will be sent
- Build and run this script once (either directly or with docker or docker-compose)
to generate a default
data/config.yamlfile. - Update the parameters in the config file to match your setup.
- Run the daemon (either directly or with docker or docker-compose)
