[Nut-upsuser] multiple usb apc smart ups with nut?

[Jelle de Jong]

Hello everybody,

I got tree UPS devices connected to a Debian server, and i am
searching for a way to configure them.

The server power-cord is only connected to one of the ups devices, and
should monitor the other ups systems to sent email status.

I got a HP R3000XR UPS with has a RS232 communication port that I have
working perfectly.

Then I have two APC SmartUPS 750V devices that are connected with USB,
but I don't know how to setup the nut configuration to deal with both
the devices.

This is my dmesg output:

Dec 14 19:36:39 sammy kernel: [ 2.221527] usb 1-3: Product:
Smart-UPS 750 RM FW:668.18.I USB FW:7.4

Power Conversion Smart-UPS 750 RM FW:619.3.I USB FW:8.1] on
usb-0000:00:12.1-1/input0

Could somebody help me with some configuration snippet to get this
working?

Thanks in advance,

...

As an flow up: I read the usbhid-ups man page, and I am using the
setup described in the attachment, it seems usbhid-ups is not
detecting the serial numbers. Any idea's?

Thanks in advance,

Kind regards,

This looks like a permissions problem. Try running the drivers as root
in debug mode:

/path/to/usbhid-ups -u root -DD -a apcup

If this works, chances are that you have not setup udev properly.

[apc1]
driver = usbhid-ups
port = auto
serial = "12345678"

[apc2]
driver = usbhid-ups
port = auto
serial = "12345678"

Your UPS devices must be uniquely identified through the 'regex'
expressions you can find in 'man 8 usbhid-ups'. Assuming these are
more or less identical units, your only hope is probably the serial
number that is reported. You can find these serial numbers through
'lsusb -v'.
