Description

This is designed to be compatible with Tuya Smart Switch https://www.aliexpress.com/item/4000615022697.html. Original switch has relays. Replace the relay control board with this, and load esp-homekit-devices (HomeKit Accessory Architect) or your own firmware. Control the dimmers with a PWM signal. Note full scale PWM is 3.3V, but fullscale on the FL5150 dimmer control is 2.56V.
