Sonoff iFan02¶
Sonoff iFan02 is a driver for ceiling fans with lights. By replacing the old driver with iFan02, your non-smart led ceiling fan will be converted to a smart ceiling fan. For more information see iFan02
This configuration will expose a Binary Light and a Speed Fan.
To get this working in ESPHome you first need to create a Custom Output to control the iFan02.
Create an ifan02.h file:
#include "esphome.h"
using namespace esphome;
class IFan02Output : public Component, public FloatOutput {
public:
void write_state(float state) override {
if (state < 0.3) {
// OFF
digitalWrite(5, LOW);
digitalWrite(4, LOW);
digitalWrite(15, LOW);
} else if (state < 0.6) {
// low speed
digitalWrite(5, HIGH);
digitalWrite(4, LOW);
digitalWrite(15, LOW);
} else if (state < 0.9) {
// medium speed
digitalWrite(5, HIGH);
digitalWrite(4, HIGH);
digitalWrite(15, LOW);
} else {
// high speed
digitalWrite(5, HIGH);
digitalWrite(4, LOW);
digitalWrite(15, HIGH);
}
}
};
Then you need to set it up with yaml.
