Looks very good and fast delivery
Good product , does exactly what it says and works well with Alexa. circuit diagram is simple to understand and easy to install. one problem is that my original switch is a 2 state switch, meaning on is close circuit and off is open circuit but this one is designed for push button , meaning I need to turn on and off to create a pulse and only then the light will turn on . i want to change this if possible using a firmware update
