NUT Plugin not working correctly

Hi Community,

I am running NUT Tool as NetServer on a Home Assistant and an EATON USB650 connected to the HA HW.

On a different HW, I am running OMV with the NUT Plugin configured a Net Client.

The Plugin can connect to the Server an presents data from the UPS in Diagnostics/Services/UPS.

But on the dashboard the UPS service is shows a tick at Enabled but not on Running and the service status is RED.

Any idea what to look for?

What additional information do you need to assess the situation?

Thanks

Matthias

In the meantime I have found this thread: NUT Monitor can't start - Plugins - openmediavault

When running "omv-salt deploy run nut" it results in this message:

Summary for debian

-------------

Succeeded: 15 (changed=3)

Failed: 1

-------------

Total states run: 16

Total run time: 761.596 ms

[ERROR ] Service nut-monitor is already enabled, and is dead

Any idea how to proceed?

This is regularly logged in the system log:

The problem might be your password or username. If it contains special characters, then NUT will fail to parse several config files.

The problem was identified here nut error in standalone mode.

See https://github.com/openmediava…51d3653c56e95b4c83ee41ebd for more details.

Does your password contain a # or =?

Yes, it contains a "#" ... should I remove this?

Wow! This did the trick!

Thank you so much!

Update: Shutted down the server as expected! Thanks again!
