The multi wifi switch is based on an ESP 8266 Node MCU Board and the Homie ESP Library, which uses MQTT. It has 4 Buttons and 3 LEDs and therefore uses most of the usable ESP 8266 pins. The pin of a button can easily be used for a LED and vice versa. Any combination ranging from 7 buttons to 7 LEDs is conceivable.
The box itself is relativly "dumb". It relies on an external controller (like Home Assistant, IoBroker, ...) for controlling the switch.
Three different button presses are supported:
- Short single press
- Long single press
- Double press
A LED can be in one of five states:
OFF: The LED is offON: The LED is onSHORT_PULSE: The LED is blinking fastLONG_PULSE: The LED is blinking slowTRIPPLE_PULSE: The LED is blinking three times fast, makes a break and is blinking fast again
