It works with LED and Hubitat
Installation was pretty straight forward. You need to install the app and also make sure you can get this device onto a 2.4GHz WiFi network in your house. But otherwise, everything worked great. I was even able to add it to my Hubitat automation hub. It was pricey, but it solved my issue of needing both a fan and light in the same location while also being able to automate it and working with LEDs. It does all of those things. I can control it remotely from my phone and the dimming ability is great as well as configurable.

Kasa WiFi Ceiling Fan Switch: a hands-down winner
I bought one of these Kasa Wifi Ceiling Fan switches for our family room cathedral ceiling fan, & liked it so much, we bought another for our screened patio ceiling fan, & & then a couple more for 2 other rooms.The units work really well. I’m a big Leviton fan, but the Leviton WiFi fan controller requires a separate switch in the wall for controlling the light. This Kasa fan switch controls =both= light and fan.The installation was easy. The Kasa packaging & instructions were first rate. They even include a sheet of peel-off stickers for labelling each of your wires BEFORE you start disconnecting the old switch. This is the best product guide & information I’ve seen. Easy to read. Well written. Crystal clear. And, absolutely correct.The wiring installation took about 20 min, because the Kasa switch is very deep & has to go nearly all the way to the back of your switch box. Pushing all the wires and caps aside to get the switch in was most of the hard work. It’s a tight fit.ALWAYS download the Kasa TP-Link App to your phone and register the device =before= you try anything else. You will then have no problems at all with: setting up the fan & configuring it; adding widget mini-screens for the fan control to your cellphone’s desktop; & =finally=, going in to Google Home or Alexa, and setting up the fan in the correct room of your home for voice control to take over.The modern touch-screen slides for the fan speed & light intensity are a little different. You get used to them. They look great on your wall! We rarely touch them. The voice control & the Kasa Widgets for your cell phone home screen do all the work for us.Mostly, we use Google Home voice control, or the Kasa 4-speed fan widgets on our cellphone home screen.We had a problem with our patio fan: it has no light. We capped the red wire from the Kasa switch instead of connecting it to the light. I made double-sure the white neutral was firmly & solidly connected. Everything seems to work well, reliably, & normally. No problems at all without the light connection.These Kasa fan control switches are excellent. I am delighted. I will definitely be considering Kasa WiFi switches & adapters for other uses in our home.

Amazing ceiling fan and light control in one.
My house has ceiling fans in each of the bedrooms with independent light and fan switch. This smart dimmer/control was a perfect upgrade. Installation will be familiar with anyone who has replaced a light switch or receptacle in their home. This switch has some short wires coming out of it that have tinned ends pre-stripped. While the switch comes with plenty of screw-on wire nuts, I’d recommend DIYers get some lever lock wire nuts instead. Your electrician or handyman will probably bin the included wire nuts.Do check your home wiring before buying this. Not all homes are wired for independent fan/light control at the wall. Some may not be wired in a safe fashion either.Setup is a breeze via the Kasa smart home app. The switch is quickly detected and added to my Wifi network. Some added features of this switch is a soft on/off function for the light. You can even fine-tune it via the app to work with your chosen bulb. The fan control works perfectly. Simply set the chain pull on the fan to its highest speed, the wall control does the rest. You even gain a fourth speed. There is an audible hum from the fan as it starts up but once at speed it is nearly inaudible.Why dock 1 star? I also use home assistant. The Kasa app is great, but I have smart home stuff from other vendors too. There’s something with the Home Assistant Kasa integration that does not give you dimmer and speed control. You only get on/off functionality in Home Assistant. Even worse, Home Assistant turns on to 100% ignoring the last speed/dimmer setting used. Hopefully this gets fixed down the road. Google Home works fine. Gemini will have no issue operating your fan and light when you say the magic words.

Works great with compatible fan. Hereâs what you need to know:
Okay, my only real issue was not knowing it wouldnât be compatible me with my fan⦠and not knowing which fans are compatible. It seemed every fan I looked at had warnings that using wall switches may damage the fan.I couldn’t figure this out on my own, searching the web, reviews and even using AI. All I could find were videos of workarounds. I didnât want to modify a new fan and find out that didnât work. I wanted to know for sure.I went to Home Depot and they were very helpful but didnât know the answer. I called two fan manufacturers and they both told me their fans would not be compatible.I finally called Kasa support for this specific switch and they told me ANY FAN WITH PULL CHAINS SHOULD WORK. (Meaning, avoid any fan with remote controls.)So I took a gamble on a 52â Harbor Breeze Fairbanks fan at Loweâs that had pull chains. Brought it home and it was super easy to install. I had to make one minor âmodificationâ which was to separate the blue (light) wire/ and black (fan) wire so they could be wired independently to the black and red wires from the switch. Very simple.Switch works great.Hopefully this info helps someone else who is wondering what dans are compatible.Also I might reiterate for others that you need to have the proper wiring: 12/3 wiring vs. 12/2 which includes an extra hot wire. That way you have one neutral and two hot wires: One for the light and one for the fan.Iâm very pleased with the switch overall.

Works exactly as advertised
Excellent device, easy to install and very responsive from either the wall switch or the Kasa app.

Thereâs not a lot of choice for HomeKit fan controllers. This one is fine. Not sure Iâm 100% behind the touch control. You can easily adjust the speed or brightness by mistake (or lack of hand-eye control).However, the Meross fan controller is total junk. Multiple presses (like double clicks) of the fan button or the light button are used to adjust speed and brightness. Itâs somehow not quite intuitive. Worse was the Meross would disconnect from Wi-fi and never reconnect. Had to do a complete re-install each time. To be fair, the room is Wi-fi challenged, but still the Kasa works fine and seems to always be connected. Kasa also has a much better IOS app too.Keeping the Kasa – Meross fan switch goes to the yard sale with the totally total crap Wemos. My other Meross switches have no problems.

Pros:- Easy to use controls. For example, to turn the light on, just touch the light slider at the desired brightness level and the light comes on at that brightness. Fan control dimmer switches from eg Treatlife require that you first turn the light on before you can adjust the brightness, meaning you can blind yourself at night before you have a chance to dim the lights.- Easy to set up in the app.- Exposes ON and OFF events in Alexa.Cons:- The dimmer was not able to dim LED bulbs significantly even after trying bulbs from two different manufactures. The dimmer that originally came with my light+fan as well as a dimmer from Treatlife were able to properly dim my LED bulbs.- The procedure in the app to adjust the min and max dim levels is convoluted. You first have to sit through a test of several seconds before you have a chance to adjust the min and max brightness levels. In the Treatlife app, for example, you just immediately tap a slider to adjust the (min only) brightness, which is much easier.I really like these dimmers (I bought two plus a motion sensor), but I’ve given them only three stars because they could not dim properly, and sadly I have returned them and opted for dimmers from Treatlife, which, although much clumsier to use, work properly with my lights.

I would have given this five stars except for the fact that I couldn’t get one to pair with the app and until it does, it will show red flashing lights even though it will work to control the fan. I had to move one of them closer to the wi-fi hub to configure it and move a previously configured one to its former location … I had to reconfigure that one but was able to do so. I did have to try multiple times on half of them to pair them with the app but all eventually did configure … except for one which as I said above, I had to move. It appears as though one was a bit pickier on how close it was to the wi-fi. Since being installed and configured they have worked well.

It works excellent. Make sure youâre only using it for AC motors. I noticed itâs a little warm to the touch which is fine. One annoyance is that it is too easy to accidentally factory reset it by only holding either button for 5 seconds. This has already happened to me twice.

The switch I got was used… dirty and scratched. Not impressed to say the least. TP-Link is usually better than this.
