smart switch for guests

All smart home enthusiasts will know the issue - you have visitors and they are helplessly looking for a light switch, instead of admiring the level of automation that you have acomplished!

Nevermind, here is my solution.

 

I am running Home Assistant and the easiest way to set up a custom smart device is using ESPHome. 

Add the provided code below to the bare configuration code of your connected ESP32 D1-Mini and upload it.

Solder the push button between GND pin, the resistor and pin IO27 or whichever pin you decided on using. Just remember to update your code accordingly.

 

What I used:

For the look I have spray-painted the parts. Then, insert the pre-soldered ESP32, the switch and glue the two halves of the case together.

 

This switch ads a little fun to switching!

 

Here the code, just copy/paste:

 

switch:

  - platform: template

    name: "Toggle State"

    id: toggle_state

    optimistic: true

    restore_mode: RESTORE_DEFAULT_OFF

 

binary_sensor:

  - platform: gpio

    pin:

      number: GPIO27

      mode:

        input: true

        pullup: true

      inverted: true        # gedrückt = ON

    name: "Taster"

    id: taster

    filters:

      - delayed_on: 20ms    # Entprellung

    on_press:

      then:

        - switch.toggle: toggle_state

    # Optional: langer Druck als separate Aktion

    on_click:

      - min_length: 1000ms

        max_length: 3000ms

        then:

          - logger.log: "Langer Druck erkannt"
