@TosaKerry,

I would recommend looking around the forums for possible solutions. The KS230 kit communicates by sending a dimming signal from the satellite to the main, where the actual power is changed. Some people have found luck purchasing multiple KS230Kits and using the satellite for an additional, and then using the extra main in another circuit. Many users have posted diagrams of their setups, even all the way up to an 8-way configuration. 

However, we cannot provide support for devices that do not follow the setup instructions from the device. Leaving unused wires and connections in the electrical box is never recommended as this setup was never tested and poses a potential hazard. Any Setups that do not follow the wiring diagrams in the box are not supported and have no official setups. Please be aware that using the configuration that a user has posted to the forums is not official, and not tested for safety/functionality.

This is a Request that we have just now been starting to receive due to increase in focus on local communication. I would expect to potentially start seeing designated trigger devices for both Kasa and Tapo within the year, given the demand. CES may even have a first look at some of these devices.
