Display "system uptime" for humans (via MQTT)

[jedie]

In my Tinkerforge2mqtt -> HomeAssistant i expose the “uptime” of the host system in seconds via MQTT:

Another value is the “run time of the script” in seconds:

I exposed this values with:

• state_class: measurement
• device_class: null
• unit_of_measurement: seconds
• suggested_display_precision: 0

How can I change this so that the user can get reasonable values in the UI?

Maybe i should try to look into System monitor - Home Assistant sources?!?

That is a terribly inefficient way to do it.

Look at how the HA uptime sensor works.

It sends a timestamp when the system starts.

Which is displayed in the dashboard as:
