I installed two Kasa 3-way switches and left two manual 4-way switches for a 5-way configuration. I connected them to the Kasa app as paired 3-way switches.

The app does not always report the correct status of on or off. Also, if the switch is turned off at the first installed Kasa 3-way switch, none of the other switches can turn the lights on.

Any ideas?

Any thoughts on whether this woud work for the 3 way dimmer switches (KS230 Kit)?

Hi - 

I am trying to install a 4 way circuit with two HS-210 3-way switches and two dumb 4-ways in the middle. Having trouble and found this 5 year old thread online so I thought I would ask for help. 

I have successfully installed several Kasa 2-way and 3-way switches before, but this is my first attempt at a 4-way. 

All 4 paddles all work perfectly. The problem is that it usually takes two taps on the button in the app to turn the light on and off. That tells me that each smart switch can't see what the other one is doing and doesn't know whether the circuit is on or off. 

I have tried installing each end as the primary and then pairing the other. I have also tried installing one end to the wifi by itself as a "single" three way and leaving the other end unpaired and "dumb". I have also uninstalled one of the smart switches and reinstalled a dumb switch. None of these ideas work. 

In all scenarios, the paddles work just like they are supposed to but it takes a couple of attempts in the app to get the lights on or off. 

This is an improvement in that I can turn the lights on and off remotely now, but since the app can't tell definitely whether the circuit is on or off, I can't fully automate these lights like I had intended. 

Is there something I am missing? The ony thing I can think of is that the two ends of the circuit are petty far apart - about 80 feet - could that be interfering with how they are paired?

A four way smart switch right in the middle would seriously solve this problem!

 Instead of a firmware update, they should simply produce the 4-way switch that everybody here is asking for.

I have two HS230 kits setup with 4 ways in middle. Like others stated, the 3-ways work but the 4-way does not. When the 4-way is thrown when off, the 3-way senses the configuration change and turns it back off before the light comes on. When the 4-way is thrown with the light on, the light goes out momentarily while the 3-way senses the change and turns the light back on. 
I was hoping the was a configuration change in the firmware that would tell it to not switch the circuit when it senses the change. Instead it should just register the light in the new state (On/Off). This would make the 4-way work. Unfortunately, it is set to maintain the state that it believes the lights should be in. 
Why not a firmware configuration change if not making a 4-way switch?

I have one four-way in the middle and two three-way switches. I put in two smart switches for this three ways and set them up as individual switches not together. But still, it is not working correctly. Any know how to fix this.

i have one main and two satellites to configure my 4 way switch. They are version 1s because versions 2 will not work. Or at least I couldn't find a way to get them to work. That being said I had to order almost 40 used kits on Amazon which almost all of them were broke until I got working ones. Anyway in a 4 way configuration the led remains lit whether the light is on or off. At least it does for sure on the satellites. I can't remember if that is the same for the main switch. I'll double check tomorrow as I'm away from home. As far as a solution for the leds always on I don't have one. I was just glad to get it working at that point. However inovelli does make a 4 way switch but you have to purchase each switch separately which will get expensive. But a solution nonetheless. Haven't tried them yet as I already replaced my entire house when the inovelli switches were announced.

people have said they figured out how to do it so I'm trying to ask the community to see if there's something that I might've done wrong. Doesn't matter

  @Chesky-Neuman1 Like everybody else, you keep asking tp-link to produce an actual 4-way switch to replace the "dumb" switches. With enough voices, they might actually listen and produce one.
