350Mhz Fan and Light Control

I know there are now z-wave devices out there that can be used to control fans and their lights. However, they are a bit expensive. I have a number of fans in my house which are running at 350mhz.
I wanted to see if someone has thought about taking apart a a physical spare remote to an ESP8266 and then just exposing each physical switch as a momentary switch in Smart Things.
