Any chance that there might be a Honeywell plugin for the Honeywell Total Control Comfort thermostats within Axial Control?  Honeywell has a developers site with API to support their thermostats.  Currently Honeywell has two different types of thermostats, the Total Confort Control and Lyric systems

I have the WIFI Total Control Confort thermostat that is a nice system that can be controlled via app and online web browser interface, but can't change from heating to cooling dymanically which the API can do.
