ID gpio_4 of type gpio::..... doesn't inherit from light::LightState

Tags: #<Tag:0x00007fc3f5ac8f58>

Hi,
I’m trying to understand automations in ESP-Home and I have read the documentation over and over again. I made this little sketch that should turn on the LED (GPIO4) on the ESP32cam if the Dallas sensor reports a temp > 45C, but it doesn’t work

# Flashlight
output:
  - platform: gpio
    pin: GPIO4
    id: gpio_4
light:
  - platform: binary
    output: gpio_4
    name: ${hostname} light

# Individual Dallas sensors
sensor:
  - platform: dallas
    address:  0x043C01F096C08228
    name: "${hostname} Temp Sensor cam"
    on_value_range:
      - above: 45.0
        then:
          - light.turn_on: gpio_4
      - below: 44.0
        then:
          - light.turn_off: gpio_4

It errors with:
ID gpio_4 of type gpio::..... doesn't inherit from light::LightState

I must be making a fundamental thinking error, but don’t know where
Any input is greatly appreciated
thanks,

Your light does not have the id gpio_4, the gpio output does. Give your light an id and use that in your template.

And then there was Light !
Thank you so much Moderator Tom @tom_l !
This is now a valid sketch (copied below) and it works

I assumed light was some kind of “overlay” on “output” with id gpio_4 ,but there seem to be more at it.
This part I still don’t get… what is the fundamental difference between "output (gpio)" and "light"
Anyway, here is the corrected sketch (in case someone may find it useful)
It turns on GPIO4 (the flash LED) of an ESP32cam if the temp is above a certain value. (the ultimate goal is to turn on a fan, but I’m waiting for my IRF3708 MOSFET to come in)
