[Nut-upsuser] APC BGM2200B-GR – NUT compatibility and shutdown.return support

[kanka.dev | Akay Berk]

Hi,

I am considering purchasing an *APC Back-UPS Pro BGM2200B-GR (2200 VA / 
1320 W)* for a Debian/Proxmox environment and would like to clarify its 
level of support in NUT before purchasing it.

I found real-world reports showing that this exact model is detected by 
|usbhid-ups| and that basic monitoring as well as automatic host 
shutdown have been used successfully.

What I still need to know is whether the *complete unattended 
power-failure/recovery cycle* works reliably with this model.

My intended setup is:

  *

    APC BGM2200B-GR connected by USB to a Debian/Proxmox host

  *

    this host acts as NUT primary/server

  *

    additional Proxmox hosts, a QNAP NAS and other systems receive UPS
    status over the network

  *

    non-critical systems shut down first

  *

    the final Proxmox host shuts down last

Specifically:

 1.

    Has the *BGM2200B-GR* been tested directly with current NUT versions
    and |usbhid-ups|?

 2.

    Are the following readings known to work reliably?

      *

        |OL| / |OB|

      *

        |LB|

      *

        battery charge

      *

        estimated runtime

      *

        UPS load

      *

        input voltage

 3.

    Does |upsdrvctl shutdown| work correctly with this exact model?

 4.

    Does the UPS expose a command equivalent to *|shutdown.return|* so that:

      *

        the connected hosts shut down cleanly,

      *

        the UPS then switches off its battery-backed outlets,

      *

        and the outlets automatically become powered again when utility
        power returns?

 5.

    If |shutdown.return| is not available, is there another reliable NUT
    command or shutdown mode for achieving this behaviour on this UPS?

 6.

    Are |load.off|, |load.off.delay|, |load.on| or equivalent instant
    commands supported?

 7.

    Are there any known USB/HID stability issues with this exact model
    during long-term use?

 8.

    I found reports from Unraid users where the BGM2200B-GR works with
    |usbhid-ups|, but also at least one report of sporadic stale-data /
    USB communication issues. Is this known to be a UPS firmware issue,
    a Linux USB/HID issue, or something specific to the Unraid plugin?

 9.

    Is there any known reason not to use this model as the NUT primary
    UPS for multiple network clients?

I have *not purchased the UPS yet*, so I cannot currently provide 
|lsusb|, |upsc|, |nut-scanner| or debug output.

The main question for me before purchase is whether this model can 
reliably perform the full cycle:

*utility power fails → NUT clients shut down → final host shuts down → 
UPS output turns off → utility power returns → UPS output turns back on 
automatically.*

Any confirmation from users who operate this exact model would be very 
helpful.

Thank you very much.
