Hello, I would like to monitor some services in changing the status (active; running, exited or failed). Possibly to monitor all services and send the service name as topic parameter. Would that be possible?
how can I perform an autostart via systemd
It would be awesome to suspend the computer over MQTT.
Thanks
Hi
When pip-installing systemctl-mqtt on a system without graphics it fails as pycairo fails building.
Same with PyGObjects
Why is there a dependency on graphical libraries ?
Could this be removed ?
Thanks
First, thanks for your work on this. A useful tool if complete.
As highlighted in Issue request cited below. If you could make a solid set of documentation to install your tool so it can run in background and has proper security to allow operation it will be a winner. Below is what I am getting when I try to run you client as a non-root user (as is indicated by your current documentation) in a tmux session. It fails with the message :

Hi
Even when starting it with --mqtt-host iot1 --mqtt-port 1883. It still tries to connect with ssl giving the error:

Please add an MQTT LWT Topic to signal host status like: ON / OFF / DISCONNECTED . It would be great to have the Status of the host of systemctl-mqtt im Home-Assistant or any other System.
I know there is PrepareForShutdown but i is not the same.
