I am trying to choose the right thermostat and I'm new to all of this home automation stuff. I will have several heating zones in a mountain cabin. I need to keep the heat up to around 40F to prevent pipes from freezing when I'm gone, and I'd like to be able to turn on the heat before I drive up.
My research so far indicates that the Aprilaire is the device of choice. Since I do embedded computer stuff for a living, I appreciate the RS422 communication.
I have heard that the protocol the thermostat uses is available but I have not found it anywhere. Can someone point me to that? I probably won't actually build my own controller/web interface since it would take me longer than my time is worth to develop one off code, but it would be nice to know its there.
Thank you.
