Synology DSM: Make UPS status (change) available?

Describe the enhancement

It would be super cool if the status of a UPS connected to the Synology NAS was available to the HA integration.

Use cases

This way one could for example raise an alert on a power outage, i.e. when the UPS switches to "battery backup", and to then cause some action, like shut down devices...

Anything else?

You can already do this by enabling the "allow access from other Nas on the network" in the ups settings in the Synology then use the nut integration in HA

mhhh ... I've integrated it without any credentials (already some time ago), but when I try it now without credentials it fails
