Any way to do 3-way switch without wiring?

You might also find the following thread of interest. Although the author is talking about having a button on the wall to control smart bulbs, it turns out to mostly be the same device choice as a virtual three-way like you are looking for.

Just a Button? 1 button, nothing more fancy?

I am looking for a button that can stick to the wall, and I’m stuck . Scenario: Our guest bedroom has 3 lamps equipped with Cree Connected light bulbs. The room has no overhead light fixture and no light switch (old house, fixer upper), nor was it ever wired for a light switch (so nothing to go off of). Therefore, I want someone to be able to walk into the room and tap a button to turn on the 3 lamps. That’s the only functionality I’m looking for – a button that I can then program that when pressed, the connected lamps turn on/off. I’m stumped on finding something! Any recommendations on a simple SmartThings compatible button I can mount on the wall?
