Simple question about a switch

[JDRoberts]

I am in the the US and thanks for the info. The slave switch will have constant power. My goal would to be use two TP-Link Kasa switches and when you flip one the other toggles the the state of the one connected to the light. It would have to be an app or handler in SmartThings. Have you seen anything like that?

This is already available as an option in the official smartlighting feature. It’s called “mirror behavior.“ It means that when switch A turns on, switch B turns on. When switch A turns off, switch B turns off. The two can be any switches that you like as long as each can talk to the hub.

There is a community FAQ on setting it up:
