Has everything that I wanted in a smart switch: HomeKit, Wi-Fi, three way capability, multiple color options, Decor switch action (top on bottom off). Not reliable, I have had to have four switches replaced user warranty, all for WiFi connection failure.
We have updated our whole house with the Leviton Switches and Dimmers, but had forgotten about the switch in the garage, so we ordered this one, so now our whole house is complete! This switch is ONLY compatible with iPhones, so it is NOT compatible with Android devices. We love it!!! :)
As long as you have the common wire to support these light switches they are about the most stable I have used with homekit and they look and feel solid.
