Mold indicator unavailable state

[matteo-martinelli]

The problem

I have implemented the mold indicator following the documentation. In the following, the YAML:

sensor:
  - platform: mold_indicator
    name: 'Living Room Mold Indicator'
    indoor_temp_sensor: sensor.living_room_hygrometer_temperature
    indoor_humidity_sensor: sensor.living_room_hygrometer_humidity
    outdoor_temp_sensor: sensor.outdoor_temperature
    calibration_factor: 2.0

To have a suitable sensor to expose to the field outdoor_temp_sensor, I have created the following template:

- template:
    - sensor:
        - name: 'Outdoor Temperature'
          unit_of_measurement: '°C'
          state: >-
            '{{ state_attr("weather.home_city_forecast_my_city", "temperature") | float(0)}}

The result is the following:
