Daily min max temperature with time stamp

Configuration
26

I don’t like this combination of an automation setting a helper, so rather than this I would try a trigger based template sensor.

Something like this (not tested):

template:
  - trigger:
    - platform: time
      at: "00:00:00"
    - platform: template
      value_template: "{{ states('sensor.home_average_temperature') > states('sensor.home_todays_max_average_temperature') }}"
    sensor:
      - name: Home - Todays max average temperature
        unique_id: home_todays_max_average_temperature
        unit_of_measurement: "°C"
        device_class: temperature
        icon: mdi:thermometer-chevron-up
        state: "{{ states('sensor.home_average_temperature')}}"
        attributes:
          datetime: "{{ now() }}"

  - trigger:
    - platform: time
      at: "00:00:00"
    - platform: template
      value_template: "{{ states('sensor.home_average_temperature') < states('sensor.home_todays_min_average_temperature') }}"
    sensor:
      - name: Home - Todays min average temperature
        unique_id: home_todays_min_average_temperature
        unit_of_measurement: "°C"
        device_class: temperature
        icon: mdi:thermometer-chevron-down
        state: "{{ states('sensor.home_average_temperature')}}"
        attributes:
          datetime: "{{ now() }}"

I think it looks more elegant and it’s much easier to maintain. And it will be easy to replicate for annually/monthly/weekly/hourly sensors as you might want.
You can use the same triggers used on the automations suggested in this thread, if you wanna improve the one from my example.

Edit on 2023-01-12 18:41UTC: Replaced the template trigger used to detect a new day by a time patter to trigger at midnight. My intention is to reduce chance of errors and probably reduce CPU consumption a bit.
