As a licensed electrical contractor using the kasa lineup has been a real treat. I've sold and installed dozens of kasa smart switches at this point. They are easy to use, easy to install, and most of all they are brutally reliable. Unfortunately, and this truly is a shame, I will have to move to a different brand of smart switch if kasa does not soon produce a 3-way dimmer. I deal with customers in upper and middle class homes and in these situations if you can not supply a 3-way dimmer then I simply can not use your product. Please figure this out otherwise you will have this particular contractor walk off on you.
