Good day.  I have confirmed with TP-Link that they do not offer a 4-way solution at the moment.  Furthermore, using a KS205 on an intermediary in between two KS230 dimmable 3-way package also is not compatable.  My hope is that someone has found a solution or work around that allows for a 4-way set up?

Even if the intermediary switch in the 4-way set up is a non-smart or non-kasa regular toggle switch?  Does that set up work?

Any insight or advise is appreciated.  

Thanks

Chris
