@petro : thanks for sharing. i try to do the same with low battery level:

binary_sensor:
  - platform: template
    sensors:
      low_battery:
        friendly_name: low battery
        value_template: >-
          {{ is_state('sensor.battery_level' < 10 %)
             or is_state('sensor.battery_level_2' < 10 %)
             or is_state('sensor.hue_outdoor_motion_sensor_1_battery' < 10 %) }}

Independently of the batterylevel, the state of this binary sensor is always ‘off’. What i do wrong?

Thanks
