Unfortunately, we are not working on something like that. However, that request will definately be passed to our developers. Any suggestion we make sure to pass along for consideration.

I would like to echo this desire for a 4-way configuration. I have several in my home.  Furthermore, two of them incorporate a dimmer.

My suggestion would be to design switches that can be agregated into 3-way, 4-way and 5-way switch banks,  The banks could include only on/off switches, or on/off switches and a single dimmer switch to provide the desired capability.

Tj\hanks!!

I want to echo my agreement with this request. 

I have a 4 way swtich.  3 switches that can control hallway lights.

Switch 1: has red, black white ( and black and white connected togther, mine has a neutral wire in the back) 

Switch 2: has 2 red, 2 white

Swithc 3: has red black and white. (no netural wire in the back) 

Below is the simliar to the setup i can see from the switches.  I replaced the switch on the far left (Switch 1)  as shown in the diagram, with a 3 way switch from kasa.  

The problem is that the switches do not work right. Meaning i have to flip two of the slave switches to the same position and then kasa link would work.    Any suggestion on how i can fix this.  

On switch 3 there is no netural wire in the box (my other switches in the home seem to all have a netural wire)
