Radio Thermostat
From LinuxMCE
Radio Thermostat makes several thermostats that can communicate via various wireless protocols using USNAP modules. This is an attempt to bring some of the information for these thermostats into one place.
Current Models are:
CT-22 (Beginning to be depreciated) CT-30 (Also known as Filtrete 3M-50 sold in Home Depot in the U.S. with a slightly different case) CT-80
The USNAP communication modules include Wi-Fi, Zigbee and Z-Wave. Store Front
There is a Windows program to control it via Wi-Fi
These thermostats will connect on their own via a Wi-Fi Access Point back to their hosted control service and allow you to control your thermostat from any browser.
The documentation for the Wi-Fi communication API was released.
I also found this unofficial Cloud API documentation.
