Custom sensor returning state of >1 default sensor?

Configuration
1

Hi all –

Stumbling my way through Home Assistant. :slight_smile:

I am trying to make a custom sensor that will display a charging icon if my phone is charging and if it is not charging display the icon of phone_battery_level. I’ve got this so far:

template:
  - sensor:
      - name: "Phone Battery Custom"
        state: >
          {% if is_state('binary_sensor.phone_is_charging', 'on') %}
            charging
          {% endif %}

I know I can add {% else %} and add more conditions, but how do I return the state of binary_sensor.phone_battery_level? Much like I have charging if charging is detected?

Am I going about this the wrong way?

Yes :slight_smile: Forget the sensor and use this custom Lovelace card instead:

It does all the hard work for you.

Been playing with that. Is there a way to drop the title, state, etc. I just want the icon and the %.
