How to have a trigger reference two sensors

Configuration
1

I have the below automation which is working fine. However, I would like to make I change I am not sure how to do. I want my trigger to be when the outside temp (current trigger sensor) is below a different temperature sensor (sensor.nursey_temperature). I also only want this to run once a day.

Thank you in advance

trigger:
  - platform: state
    entity_id: sensor.home_realfeel_temperature
    below: sensor.nursey_temperature

For the run once a day condition, there are many examples on the forum. Here’s one:
