1 Simple Trick to Save 50% on Smart 3-Way Light Switches

The 2-Packs of smart light switches lead a lot of people to believe that you have to replace both light switches- but do you? #smarthome #electrical #homehack

Very useful.. I have a 3-way switch at the top of the stairs, and the second one on an inconvenient wall downstairs: I'd like to just put a wireless switch at the bottom of the stairs to control the downstairs switch and I think this helps me do it. Thanks.

When energizing a circuit with the exposed conductors sticking out of the box, stick a wire nut or wago on each conductor. It won't protect the serious Darwin contenders, but it reduces the chance of someone simply brushing against a hot conductor as they walk down the hall.

Excellent video and explanation!!! I did learn the hard way to read and reread the little manual that comes with the switches. I only had two, 3 way switches left on hand, and didn’t want to order just one single pole smart switch, but I wanted all the switches in the room to look the same. So I just used two, 3 way switches. The circuit never worked. Only one switch would work and the other switch would only work if the main switch was on. Turns out the brand of smart switch will only work if only one switch on the circuit is a 3 way switch, not both. I ordered the single pole version of the smart switch and it now works great. There was a notation in the little manual, and I didn’t see it until I reread the manual a few times out of frustration.

Thanks! This saved me a LOT of guesswork and cussing. Super easy to understand and implement.

THANK YOU. GOOD direct answer to this question.

I installed only one smart switch at the main switch (power line from breaker) . It works fine when manually turn on/off at either smart or standard 3-way switch. However, the Kasa and Alexa apps do not show the light status correctly so I am not able to know whether it is on or off to turn off or on. It does switch the light on/off at the app when I click the button on the app. The schedule setup doesn't work as I set up to turn off at sunrise and on at sunset. I tried using timer schedule on/off too but same problem. I tried multiple of these smart switches but had the same problem. I think there is some kind of firmware problem. There is also another problem the light status at the smart switch always show on even the light is off, this status light should be on only when the light is off and on when the light is off

Question for you...I have one light control by 3 switches and to complicate things the electrician ran the power to the light not to a switch box. Is there a way to wire this light up with a smart switch and still be able to use all three switches? Thanks in advance for any insight you can offer. Currently I have removed all switches and have a smart bulb that I control via wifi.

For the TP-Link 2-pack dimmer switches such as KS230, the specs note that 1 switch is the Main switch (Wi-fi active) and 1 switch is the Satellite switch. I imagine the Satellite switch is not Wi-Fi active, correct? If that is the case, then I'm not seeing the cost benefit here since you can't use each switch on 2 different 3-way setups. Do you have a method that works here though?

[PS-czsx]

it doesn't seem to work with the Leviton DW6HD, maybe they are differnt?

[bhaktano]

Unfortunately I don't see this working with the DIMMABLE version of Kasa Smart WiFi switch because the dimmer kit comes with one smart switch and one satellite (not smart switch). It works well for the non-dimmable 3-way kit since that kit has 2 smart switches in the box.

How do you handle it if the switch requires a neutral? I have a bundle of neutrals bundled on one but in the box, but 2 circuits in the box. From what I’ve come to understand, those neutrals shouldn’t be bundled. I guess my second question would be, if the smart switch requires a neutral, but the opposite 3 way switch doesn’t, can I make that work? Thank you!

[tonylozzi]

Why do sone of these smart 3-way need a neutral (white) wire connected?

[charifelkanawati]

Wow... I really liked your video and the comments and responses are not hostile as one tends to find. I have a smart 3 way dimming Kasa + 3 way dumb non-dimming and it is not working. I need one to be white and one black and unfortunately Kasa doesn't do but white. Any tricks to make it work?

[testtai]

If the switch has two common/live wires, then it's the main switch?

[paulhouser]

I'm a bit unclear on the wiring of the 2 way switch. Which of the travelers coming from the 3-way do I hook up to the 2-way, presumably as the "live" source? Thanks for your help!

[frankmoralesiii]

Well that is exactly what I did I tried my Smart three-way switch in both locations either way it only works when the other switches on

[wislord]

Interesting video, thanks. Are you using wire cutters to pull the wires out instead of pliers? You probably don't want to reuse such endings as the might be damaged. Also labeling should be recommended when power is off. Otherwise it's a huge risk of touching exposed ends of hot..

[CarlosSanchezonGoogle]

I almost thought that you meant that you're able to use a normal non 3-way smart switch for a 3-way switch. Had to go back to realize you still need a 3-way switch, which makes more sense.
