If you can get an Eaton unit of similar style, I'd go with that. The APC
Back-UPS provide minimal useful capability.

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.
