Setting up the Network UPS Tools addon for UPS with SNMP protocol

[DivanX10]

I collected information bit by bit on how to add a Powerman Online 1000 UPS to Network UPS Tools, which is available via the SNMP protocol, and which is not related to Home Assistant. I post a ready-made and working solution.

1. Install the Network UPS Tools addon
2. In the settings of the Network UPS Tools addon, add the config.

users:
  - username: username
    password: password
    instcmds:
      - all
    actions:
      - upsmon = slave
devices:
  - name: Powerman_Online_1000
    driver: snmp-ups
    port: 192.168.1.67
    config:
      - desc = PowermanOnline 1000
      - community = public
      - snmp_version = v1
      - pollinterval = 30
mode: netserver
shutdown_host: "false"

3. In the Network UPS Tools addon settings, enable port 3493 so that you can add the NUT client.

4. Launch the Network UPS Tools addon

5. If everything went smoothly, then install the Network UPS Tools client. You don’t need to enter your username and password.
   

6. Done. The Powerman Online 1000 UPS is now available in Home Assistant, running on the SNMP protocol.
