Multiple UPS of the same type, netserver

[dvdwsn]

I’m trying to get 2, APC UPS’ of the same model connected to NUT.
In the log it seems to be seeing both correctly, but the 2nd UPS is showing as unavailable.

Here is my YAML.

users:
  - username: *****
    password: *****
    instcmds:
      - all
    actions: []
devices:
  - name: myups1
    driver: usbhid-ups
    port: auto
    powervalue: 1
    config:
      - serial = B*********
      - vendorid = 051d
      - productid = 0002
  - name: myups2
    driver: usbhid-ups
    port: auto
    powervalue: 0
    config:
      - serial = J*********
      - vendorid = 051d
      - productid = 0002
mode: netserver
shutdown_host: true
list_usb_devices: true

If I connect just one at a time, it works fine.
lsusb shows both devices.

Don’t know if this makes a difference or not.
I see powervalues are different? Since same model and type shouldn’t they be the same?
Are serial numbers, full and complete as possible?

Network UPS Tools (NUT) add multiple devices

Hello everyone, I have two UPSs and would like to monitor them both with the NUT server installed on Home Assistant. I managed to configure the server with a device but I can’t but I don’t know the syntax of how to insert a new device into the configuration. my configuration is as follows: users: - username: xxxx password: xxxxxx instcmds: - all actions: [] devices: - name: smartups1 driver: snmp-ups port: xxx.xxx.xxx.xxx config: - snmp_version = v3 …

Seems it doesn’t like it. There is another way via MQTT and snmp.

Apcupsd for multiple UPS

Currently have the apcupsd component working but would like to be able to add multiple ups or add apcupsd_2:…:etc components. Thanks!

I believe the powervalue variable is to identify which UPS the host is connected to for power. 0 in this case is telling it just to monitor that system.

The serials are as complete as I can see. I got the serial numbers from the NUT integration itself.

In this post, they successfully got things worked by using the serial numbers. I did the same, but no luck.

Network UPS Tools (NUT) add multiple devices

I know this is way way late to the party but just went through this. So hopefully someone finds this helpful. Set up the add on and add each UPS individually/separately into the integration to get the serial. [Screenshot at 2025-04-23 06-43-12] Add to Devices in AddOn.

Any other ideas?

What about VendorID and ProductID? Have you looked for those (numbers versus names)? Order of the Ids may be important here also.

They are the same Vendor and Product IDs unfortunately.
