Solved: NUT integration (Network UPS Tools) no longer provides diagnostic entities

NUT integration only gives me 3 sensors but all the diagnostic entities like

- entity: sensor.qnapups_battery_runtime
- entity: sensor.qnapups_beeper_status

are unavailable.
Some time ago they worked fine.

Any idea why they are unavailable now?

The NUT server is the built in server in my qnap NAS.

Ups, my bad. I forgot to enable the diagnostic sensors.
Sorry to bother.
