Change ecobee fan run time based on Govee temperature sensor threshold

Configuration
1

I just got started with Home Assistant this past weekend, and the first automation I am attempting is to control the “fan min run time” setting on an ecobee 3 lite thermostat based on a temperature reading from a Govee thermometer in the attic. The AC/furnace and ducting are in the attic so the fan cannot circulate without conditioned air during a hot day, but I would like for the fan run time to change from 0 to 15 minutes if the temperature in the attic is within a threshold. It looks like the binary sensor threshold and circulate switch are both working as expected based on the temperature, but it is not changing the fan min on time. I feel like I should be close based on other examples, but can’t quite get it.

Home Assistant 2023.7.3 running in Docker on Raspberry Pi.

I have no clue what I was trying to do with the switch. I’ve added to automations.yaml, but I still can’t get anywhere.

- id: circulate_upstairs_air
  alias: 'Circulate Upstairs Air'
  #initial_state: off
  trigger:
    - platform: state
      entity_id: binary_sensor.attic_fan_threshold
      #from: 'off'
      #to: 'on'
  condition:
    - condition: state
      entity_id: binary_sensor.attic_fan_threshold
      state: 'on'
  action:
    - service: climate.set_fan_min_on_time
      target:
        entity_id: climate.upstairs_thermostat
      data:
        fan_min_on_time: 15

Well, I’m stupid and didn’t realize the automation was disabled and had to be enabled. Not sure if I feel better or worse that it was that simple.

Here is what I have working. Is it “OK” to have three different automations for a fairly simple task, or could this be cleaned up and turned into one or two automations through better use of conditions, if/else?
