Add Chacon DI.O remote control support in Domoticz

Page under construction

I use a 433MHz emitter connected to an Arduino Uno board to integrate Chacon DI.O wireless power plugs into Domoticz.

Needed hardware

  • Arduino Uno R3 board (available on Amazon) with USB cable
  • 433Mhz RF transmitter and receiver (available on eBay)
  • DI.O by Chacon power plugs with remote


It is very simple. Just connect the RF 433 receiver and transmitter like this:

  • GND to Arduino pin GND
  • VCC to Arduino pin 5V
  • DATA IN (receiver) to Arduino DIGITAL pin 2
  • DATA OUT (transmitter) to Arduino DIGITAL pin 11

Then I suppose you have the Arduino connected with a USB cable to a PC running the Arduino development environment.

// Enable debug prints to serial monitor
#define MY_DEBUG

  present(CHILD_ID_DIO_3, S_LIGHT, "DI.O Prise 3");
void loop()
  // Send locally attached sensor data here
void receive(const MyMessage &message) {
  // New status requested for DIO switches
  if( (message.type == V_STATUS)
      && (message.destination == getNodeId() )
      && (message.sensor >= CHILD_ID_DIO_1) 
      && (message.sensor <= CHILD_ID_DIO_3) ) {
    transmitter.sendUnit(message.sensor, message.getBool());
