    sda: GPIO26
    scl: GPIO27

Hi bellad17, did you have any luck? I tried with a GPIO switch, but it gets instantly reverted to off every time I turn it on in the Home Assistant GUI:

switch:
  - platform: gpio
    pin: GPIO32
    name: "Camera stream"
3

It sais “while its inactive” but the only way i was able to start it back up was to make a button that toggles the reset_pin

try this. It will just give you 1 button that will power down or reset depending on the state of the camera.

switch:
  - platform: gpio
    name: 'Power Down Kitchen Cam'
    id: power_down
    internal: true
    pin: 
      number: GPIO32
      allow_other_uses: true
    inverted: false

    

button:
  - platform: restart
    name: "kitchen Cam Restart"
    internal: true
    id: restart_cam

  - platform: template
    name: "Power Down/Reset"  
    id: power_down_reset
    on_press:
      then:
        - if:
            condition:
              switch.is_off: power_down
            then: 
              switch.turn_on: power_down
            else:
              - if:
                condition:
                  switch.is_on: power_down
                then:
                  button.press: restart_cam

@bellad17

I’m struggling with the same idea and when I try the upper code I’m getting the this error in ESPHome

Does this no longer work since ESPHome 2024.xx??
