This is the world’s first AC dimmer based on ESP32/ ESPHome, that truly compatible with Home Assistant, so the users can directly control the AC lights/fans easily with HA on phone.


There many DIY “dimmer” in the internet, but many of them actually used PWM for cutting the AC ON/OFF, this is not good, as it will make the lamp blink; a true “dimmer” should firstly detect the AC zero-crossing point, and then control the triac to chop the AC.


Makerfabs Home assistant AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC.Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay is implemented to make the AC totally On/Off.
