> Open-source AC dimmer modules and libraries for ESP32, Arduino, and ESPHome. Phase-cut TRIAC dimmers with hardware, software library, documentation, and ready-made integrations for Home Assistant, ESPHome, Blynk, and ESP RainMaker.
RBDimmer is a hardware and firmware ecosystem for controlling AC loads (lights, heaters, fans, motors) with microcontrollers. Products range from 4A to 40A single- and multi-channel dimmer modules. All products are compatible with the rbdimmerESP32 Arduino library and DimmerLink UART/I2C controller for high-channel-count applications.
