Integration in Home Assistant 🏠

To integrate Uptime Kuma in Home Assistant, use the integration available via HACS.

In the setup you then enter an IP, the port, username and password of your user.

Once you have done this, you have also directly integrated all sensors into HomeAssistant:

With the help of the uptime-card you can also use it to create beautiful dashboards.

Together with auto-entities, you can even build a completely dynamic dashboard that automatically displays all sensors:

type: custom:auto-entities
filter:
  include:
    - entity_id: binary_sensor.uptime*
  exclude: []
sort:
  method: state
  reverse: true
card:
  type: custom:easy-layout-card
  layout_type: vertical
  cards:
    type: custom:config-template-card
    entities:
      - this.entity_id
    card:
      type: custom:uptime-card
      entity: this.entity_id
      ok: 'on'
      ko: 'off'
      update_interval: 30
      icon: mdi:server
      ko_icon: mdi:server-off
      status_adaptive_color: true
      alias:
        ok: Up
        ko: Down
      hours_to_show: 12
      icon_adaptive_color: false
      average_template: '[[[ return variables.uptime.toFixed(2); ]]]% uptime'
      bar:
        spacing: 4
        height: 75
        round: 4
      show:
        average: true
        status: false
      alignment:
        status: spaced
        header: spaced
        icon_first: false
      tap_action:
        action: url
        url_path: '{{ state_attr(this.entity_id, ''monitor_url'') }}'
      init:
        - animation: reveal
      blink:
        target: status
        effect: fade
        speed: 10

The dashboard or card could then look like this:
