Summary

If youre uncomfortable with that, then have a licensed electrician come implement the switch.

I was comfortable doing the installation so it only took me about 5 minutes to complete.

This switchdoesrequire a neutral wire to function, by the way.

Once in the TP-Link Tapo app, the main thing I had to configure was the dimming functionality.

you’re able to customize the default state for when the switch turns on.

I left mine to be in the last “on” state.

I really enjoyed having the option to determine what happens when power is lost and then restored.

I want the switch to turn off.

While the overall design is nice, and it functions well, there are two drawbacks.

For starters, in my bedroom, the fan and light are reversed from what they typically are.

Normally, the light is the first switch and the fan is the second whenever you enter a room.

Thats a minor inconvenience, but one I think is worth noting.

The other drawback is the touch interface.

Touch is fine for dimmer controls, and actually, I prefer touch for choosing my brightness.

Its also fine for choosing the fan speed.

However, using touch for the power status of either the fan or light isn’t great.

You could brush up against the switch and accidentally turn either of them on or off.

Or, as I did, turn the light on multiple times while putting the cover plate back on.

Overall, the aesthetic is nice.

you’re free to customize how the LEDs look, and the functionality is pretty good.

Thats how my wife and I mostly use the KS240.

We also have a scene called Goodnight that shuts off all lights and locks the doors.

This keeps dust from flying around and also makes it simple to clean the fan if needed.

This is my favorite part of the switch.

Being able to ask Siri to control the fan has been fantastic.

This is my first smart fan controller, but it won’t be my last.

It’s a great value and functions well.
