systemctl-mqtt

MQTT client triggering shutdown on systemd-based systems

Setup

$ pip3 install --user --upgrade systemctl-mqtt
$ systemctl-mqtt --mqtt-host HOSTNAME_OR_IP_ADDRESS

On debian-based systems, dependencies can optionally be installed via:

$ sudo apt-get install --no-install-recommends python3-dbus python3-gi python3-paho-mqtt

Schedule poweroff by sending a MQTT message to topic systemctl/hostname/poweroff.

$ mosquitto_pub -h MQTT_BROKER -t systemctl/hostname/poweroff -n
