Here is the ESPHome code you need to convert a 3-Speed Desk Fan using a #Sonoff Basic.

          then:

              - lambda: 'return id(temp).state < (id(thermo).state + 3.0);'

              - lambda: 'return id(temp).state < (id(thermo).state + 5.0);'
          then:

      - if:
          condition:
            or:
              - binary_sensor.is_off: ${name}
              - lambda: "return id(temp).state < (id(thermo).state - 0.5);"
          then:
            - switch.turn_off: relay1
            - switch.turn_off: relay2
            - switch.turn_off: relay3

Below is the 'custom Sensor' needed to get a thermostats attribute in to ESPHome

- platform: template
  sensors:
    thermostat:
      value_template: "{{ state_attr('climate.bedroom_cooling', 'temperature') }}"
