Track your phone battery level

iOS Devices

If you have a device running iOS (iPhone, iPad, etc), The iCloud integration is gathering various details about your device including the battery level. To display it in the Frontend use a template sensor. You can also use the battery sensor device class to dynamically change the icon with the battery level.

  - platform: template
        friendly_name: iPhone Battery
        unit_of_measurement: '%'
        value_template: >-
            {%- if state_attr('device_tracker.iphone', 'battery') %}
                {{ state_attr('device_tracker.iphone', 'battery')|round }}
            {% else %}
                {{ states('sensor.battery_iphone') }}
            {%- endif %}
        device_class: battery

Android and iOS Devices

While running the Owntracks device tracker you can retrieve the battery level with a MQTT sensor. Replace username with your MQTT username (for the embedded MQTT it’s simply homeassistant), and deviceid with the set Device ID in Owntracks.

  - platform: mqtt
    state_topic: "owntracks/username/deviceid"
    name: "Battery Tablet"
    unit_of_measurement: "%"
    value_template: '{{ value_json.batt }}'
    device_class: battery
