I reluctantly ordered this wifi ceiling fan switch because the advertising said: "not for remote-controlled ceiling fans". My 18-year-old, "remote-controlled" ceiling fan is on a 20 ft ceiling and not easily replaced. With a little experimenting, I wired in the SmaFan switch. The fan now works fine with the switch and the phone application! I can even access all 3 speeds. The only issue I have is that the fan-light only works with the original remote switch ...which I never use the light anyway. The reason I marked it 4 stars instead of 5 stars is the instructions for wifi-connectivity were a bit unclear and it took me a while to connect. the switch connected to Bluetooth, though, without a problem. It even now works with Alexa! (For those interested, I discovered I had to have the fan set at full-speed with the original remote before wiring in the new switch.)
