Wifi control for RF remote
TV Food Maps wrote 12/22/2014 at 16:36 • 2 pointsHi, I have 2 different RF remotes, one controls a fireplace in my house and one controls a firepit outside. I'd love to be able to turn these devices on using my phone. My thought was to find something that could record the signal sent from the remote and "replay it" when triggered by a command over wifi. I'm good with the programming side of things what I can't seem to find is something that can record the RF signal and replay it (and can be triggered via something other than physically pushing a button). Any thoughts?

Check out this Instructable (http://www.instructables.com/id/Cheap-Home-Automation-using-Wireless-Outlet-Module/) for some ideas on how to reverse engineer the RF signal. Most of the home RF stuff I've seen is in the 433MHz range, so I doubt your phone would be able to reproduce something on that spectrum without a dongle attached to it. What I've seen some people do is to hook up a microcontroller to the remote control for the device and just simulate the button press with it. You can run a webserver on the micro to provide the interface your phone can access.
I've just started a similar project (although I haven't created a project page for it on here yet) where I'm switching out the RF receiver in a remote outlet for an ESP8266 module so that the outlet will connect directly to my WiFi. I found that the ESP08266 had about twice the range as the 433MHz RF transmitter, so it would allow me to have remote outlets anywhere in my house and still be reliably in range. Good luck to you on your project!
