Using Inspiration from here for wiring:

I have managed to make my dumb diffuser into a smart one with a D1 Mini + ESPHome!

Parts (so far)
Wemos D1 Mini
100 ohm resistor
Wire
Optocoupler PC817

Working:
On (mimics 1 button press)
Off (mimics a further 4 button presses)
ON/OFF State (Reads Voltage via ADC pin to + pin on Ultrasonic Disc)

To do (help appreciated)
LED control (runs off a rotary encoder - need to work out how to mimic the output of this with the D1 mini to control LED light)

    internal: True
    update_interval: 5s
    filters:
      - multiply: 3.3
    on_value_range:
      - above: 0.01
        then:
        - binary_sensor.template.publish:
            id: binary_switch
            state: ON
      - below: 0.01
        then:
        - binary_sensor.template.publish:
            id: binary_switch
            state: OFF

I will add more photos and information on wiring later

Any help with how to control LED light would be great! Plan on measuring remaining pins on the rotary encoder to see what they read when being turned.
