Тоже задавался данным вопросом. Данные выключатели есть с радио управлением. И на плате есть разъем для радиоприемника. Один из контактов это RX.
Если используете ардуину:
int txPin = 9; // pin connected to RF transmitter
int i; // counter to send command pulses
int pulse; // count pulse repetitions
int incomingByte = 0; // for incoming serial data
// hard coded commands (see txButton): 1 - pulse start, 2 - zero, 3 - one, 4 - pause, 5 - low

Соединяете земли и выбранный пин с RX на плате. Программируете по на определенную последовательность и шлете команды.
Все отлично работает. Так же работает команда на выключение.
Пока эксперименты приостановил. Но следующим хотел найти как его можно напрямую включить или по UART
