I read a review saying it's HomeKit compatible and after installing it I find out otherwise. It took me a little while to find the app on the App Store and I had to download a few before I found the right Legrand app. It dims, which is why I think so, but there's a big lag between the slider in the app and the actual dimming. I have to say it's coming back. It only took 10 minutes to realize it was a bad buy. It really looks like KMart dimmer plugs.
