Tenplate sensor goes to unknown

[PatrikHAOS]

Hi!

I've noticed that from time to time sensor that I use with this macro becomes "unknown" at midnight

This is the current state
{% from 'cheapest_energy_hours.jinja' import cheapest_energy_hours %}
{{cheapest_energy_hours('sensor.nordpool',hours=3, lowest=true, value_key='price', time_key='time') }}

below is screenshot, I was actually upp and noticed and the remedy when this happens is to reboot HA, reloading YAML does not restore the sensor. I have noticed one way of "Forcing" this issue is that you update some random other component and do not restart HA.

Did you create it in YAML or as a helper in the GUI?
In case of YAML can you share the full code? In case of helper, can you share all the settings?

And what was the state of the source sensor while the template sensor wasn't working?

Hi

attached the input sensors aswell

I have both types, see below

      - platform: state
        entity_id: sensor.nordpool
      - platform: state
        entity_id: input_number.requiredhoursheating
      - platform: homeassistant
        event: start
    action:
      - variables:
          heating_data: >-
            {% from 'cheapest_energy_hours.jinja' import cheapest_energy_hours %}
            {{ cheapest_energy_hours('sensor.nordpool', mode='split', hours=states('input_number.requiredhoursheating')|int(0), value_key='price', time_key='time', split='true', min_split_hours=3) }}
sensor: 
      - name: "Heating schedule"
        unique_id: HeatingSchedule1
        state: "OK"
        attributes:
          Heating_windows: "{{ heating_data|length -1 }}"
          Heating_Window_1_Start: "{{ heating_data[0].start if heating_data is iterable and heating_data|length >= 2 else 'None' }}"
          Heating_Window_1_Length: "{{ heating_data[0].hours if heating_data is iterable and heating_data|length >= 2 else 'None' }}"
          Heating_Window_2_Start: "{{ heating_data[1].start if heating_data is iterable and heating_data|length >= 3 else 'None' }}"
          Heating_Window_2_Length: "{{ heating_data[1].hours if heating_data is iterable and heating_data|length >= 3 else 'None' }}"
          Heating_Window_3_Start: "{{ heating_data[2].start if heating_data is iterable and heating_data|length >= 4 else 'None' }}"
          Heating_Window_3_Length: "{{ heating_data[2].hours if heating_data is iterable and heating_data|length >= 4 else 'None' }}"
          Heating_Window_4_Start: "{{ heating_data[3].start if heating_data is iterable and heating_data|length >= 5 else 'None' }}"
          Heating_Window_4_Length: "{{ heating_data[3].hours if heating_data is iterable and heating_data|length >= 5 else 'None' }}"
          Heating_Window_5_Start: "{{ heating_data[4].start if heating_data is iterable and heating_data|length >= 6 else 'None' }}"
          Heating_Window_5_Length: "{{ heating_data[4].hours if heating_data is iterable and heating_data|length >= 6 else 'None' }}"
