Set min/max temperature from midnight

Configuration
1

Hello

using python_scripts.set_state i write an automation that set a min/max temperature from midnight, but i don’t understand why the automation set both min and max sensor in a same time with the same value… FIXED

sensor:

- platform: template
  sensors:
    min_temp_outside:
      friendly_name: "Temperatura minima"
      value_template: "0"
      unit_of_measurement: °C
    min_temp_outside_time:
      friendly_name: "Ora temperatura minima"
      value_template: "0:00:00"
    max_temp_outside:
      friendly_name: "Temperatura massima"
      value_template: "0"
      unit_of_measurement: °C
    max_temp_outside_time:
      friendly_name: "Ora temperatura massima"
      value_template: "0:00:00"

automation:

alias: outside temp

  - platform: time

I assume you know that the value set by python_script.set_state is temporary and doesn’t survive a restart (which is probably why you added the Homeassistant Start trigger).

If you are interested, it’s now possible to create Trigger-based Template Sensors to do the same thing as what you posted above but without the need for python_script.set_state, an automation, or an input_datetime.

Here’s an example that records the maximum daily temperature and the time when it occurred.

Yes the value setted by set_state in temporary.

thank you for your suggestion, im looking the script
