I recently bought and installed a Cyberstat 1201 which cost me roughly $80 and was pretty simple to wire in, connect via my WiFi, and is really wonderfully easy to control with my smartphone. I'm a pretty thoroughly analog guy, so if it went smoothly for me, it's not rocket science I had one question during install about powering it and sent an email and had a very informative response in less than an hour. I've wanted this functionality for years but been unwilling to pay for a 'Nest' or some glitzy ubercomplicated device. I have no commercial affiliation whatsoever with this company, merely want to spread the word about an affordable product that works well. Google Cyberstat 1201 and you will find it.
