Fan/light controller with single wire?

I’m very new to SmartThings, acutally, (I haven’t even received the hub yet, so bear with me) and I’ve been looking around for something that will replace my RF light/fan controllers in my ceiling fans. Currrently I have RF remotes in the wall that control and dim the lights and adjust fan speed. The fan itself only has a single 2 conductor to it which powers the fan and RF receiver that controlls the fan. I’ve been unable to find something similar that I could use with SmartThings, does something exist? What options do I have?

This is discussed a lot on the forum. For starters here is 2 topics you could read through. I’m sure there is even more.

Hope that helps.
