Home Assistant device tracker which uses OpenWRT's ubus.

• Install HACS - HACS Setup.
• Add https://github.com/teddybeermaniac/HomeAssistant.UbusAdvanced repository to HACS - HACS Custom Repositories.
• Install the integration using HACS.

• Create a /usr/share/rpcd/acl.d/homeassistant.json file. Adapt /tmp/dhcp.leases according to leasefile options in your /etc/config/dhcp configuration file (you can use wildcards here):

  {
      "homeassistant": {
          "description": "HomeAssistant Ubus Advanced integration",
          "read": {
              "file": {
                  "/tmp/dhcp.leases": [
                      "read"
                  ]
              },
              "ubus": {
                  "file": [
                      "read"
                  ],
                  "hostapd.*": [
                      "get_clients",
                      "get_status"
                  ],
                  "uci": [
                      "get"
                  ]
              },
              "uci": [
                  "dhcp"
              ]
          }
      }
  }

  See OpenWRT Wiki ubus/ACLs for more details.
• Add /usr/share/rpcd/acl.d/homeassistant.json to /etc/sysupgrade.conf file to prevent it from being deleted during upgrade.
• Add a section to /etc/config/rpcd. The password can be generated using uhttpd -m password:

  config login
          option username 'homeassistant'
          option password '$1$$I2o9Z7NcvQAKp7wyCTlia0'
          list read 'homeassistant'
          list write 'homeassistant'

  See OpenWRT Wiki ubus/Authentication for more details.
• Restart rpcd /etc/init.d/rpcd restart.

• Add device tracker to configuration.yaml. Use your router's IP, or hostname and username, and plaintext version of password that you added to /etc/config/rpcd:

  device_tracker:
    - platform: ubus_advanced
      host: http://192.168.0.1
      username: homeassistant
      password: password
      # Example options
