Ok, If I'll get an SNMP-card, would I have better control over the ups.

With best regards

It looks like this might be using the upscode2 driver (UPScode-II protocol), right?

The upscode2 driver does not seem to support the segments, although this is a limitation of that driver rather than the rest of NUT. I have not looked into the protocol document too much, but it should be possible to add this. (It would probably be best if we could find someone with a spare UPS who is willing to test, though - you might not want to do this in production.)

I do not use upsched (which is generally necessary for shutting down after a specified time on battery, rather than when the UPS determines that the battery is low), but it should be possible to do this even without controlling the segments.

Perhaps someone else with more recent experience can comment on this.

I also have not used a Synology device, but as I recall, they generally expect to be the NUT master system. This may cause problems if you need to do something fancy with upssched.
