[OpenTRV-dev] 2 way and monitoring

[Kevin Wood]

Hi Bo,

The RFM12Pi is a good step towards getting the data into a Pi, IMHO. It's
really just an RFM12 hanging off a MEGA328 with the Pi connected to the
serial port. Plenty of scope for doing different things with it, and it
can be flashed straight from the Pi.

Yes, you could probably make one slightly cheaper but, for the saving in
time, It's worth the price as you can have it up and running in minutes.
