To display it in the Frontend use a [template sensor](/components/sensor.template/). You can also use the icon template option to create a dynamic icon that changes with the battery level.

The `else` part is used to have the sensor keep its last state if the newest [iCloud](/components/device_tracker.icloud/) update doesn't have any battery state in it (which happens sometimes). Otherwise the sensor will be blank.

While running the [Owntracks](/components/device_tracker.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.
