Works as expected. easy to install and easy to integrate into my Alexa. Controls fan and light separately without any problem. I would but again.

On peut varier la vitesse du ventilateur et aussi la lumière DEL indépendante et à bas vitesse le moteur n’est pas bruyant comparé a un autre variateur de vitesse

Very easy to control the fan and lights. The dimming is very easy to manipulate, tap the + or - to change brightness in increments or hold for a continuous change in brightness then release at the desired setting. No delay for controlling the brightness it remains the same at the point of releasing the button. Some devices have a delay where the brightness continues to change after releasing the buttons. The best feature of this device is the app. Control your fan and light from anywhere in the world with an internet connection, select your desired fan speed or vary the lamp brightness as your hearts content. Set up schedules and timers to run the fan at specific speeds and or lamp brightness. This is just awesome!Installation is not for the average joe you will be working with electricity and need to take the necessary precautions.UPDATE:So I've been using this for almost a year now and I found that the schedule doesn't work very well. Whenever you create a scheduled task there is a slider that allows you to activate or deactivate (on/off) the task. I find that these keep on turning themselves off and as a result the schedule doesn't work properly.
