```bash

   lsusb
   ```

   You should see an output similar to:

   ```
   Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
   Bus 001 Device 019: ID 09ae:2012 Tripp Lite
   ```

   ```bash

   sudo apt update
   sudo apt install nut nut-client nut-server
   ```

   ```bash
   sudo nut-scanner -U
   ```

   You should see an output similar to:

   ```
   [nutdev1]
           driver = "usbhid-ups"
           port = "auto"
           vendorid = "09AE"
           productid = "2012"
           product = "Tripp Lite UPS"
           vendor = "Tripp Lite"
           bus = "001"
   ```

Make sure to replace the names with those of your UPS devices - the generic ushid driver is fine most of the time, but it might depend on your UPS.

   ```bash
   sudo nano /etc/nut/ups.conf
   ```

   Add the following configurations:

   ```ini
maxretry = 3
pollinterval = 1
[APC1400VA]
    driver = usbhid-ups
    port = auto
    vendorid = "051D"
    productid = "0002"
    desc = "APC 1400 VA USB UPS"

[Trust1500VA]
    driver = nutdrv_qx
    port = auto
    vendorid = "0665"
    productid = "5161"
    desc = "Trust UPS 1500VA"

[EATON1150VA]
    driver = usbhid-ups
    port = auto
    vendorid = "0463"
    productid = "FFFF"
    desc = "EATON UPS 1150 VA"
   ```

   ```bash
   sudo nano /etc/nut/upsmon.conf
   ```

   Add the following lines:

   ```ini
   MONITOR trust@localhost 1 admin secret master
   MONITOR apc@localhost 1 admin secret master
   MONITOR eatonk@localhost 1 admin secret master
   ```

   ```bash
   sudo nano /etc/nut/upsd.conf
   ```

   Change:

   ```ini
   LISTEN 127.0.0.1 3493
   ```

   To:

   ```ini
   LISTEN 0.0.0.0 3493
   ```

   ```bash
   sudo nano /etc/nut/nut.conf
   ```

   Set:

   ```ini
   MODE=netserver
   ```

  ```bash
   sudo nano /etc/nut/upsd.users
   ```

   Add the following:

   ```ini
   [monuser]
     password = yourpwd
     admin master
   ```

  ```bash
    sudo nano /etc/udev/rules.d/99-nut-ups.rules
    ```

    Add the following rules:

    ```ini
    SUBSYSTEM!="usb", GOTO="nut-usbups_rules_end"

    # TrippLite
    ACTION=="add|change", SUBSYSTEM=="usb|usb_device", SUBSYSTEMS=="usb|usb_device", ATTR{idVendor}=="09ae", ATTR{idProduct}=="2012", MODE="664", GROUP="nut", RUN+="/sbin/upsdrvctl stop; /sbin/upsdrvctl start"

    LABEL="nut-usbups_rules_end"
