We just took on a line of internet-capable HVAC thermostats, and they gave me one for personal use to try out. This thing is the bomb! From my computer or smart phone I can check the temp, change the settings, turn the fan on/off, reprogram the schedule, get usage graphs, etc. It will even send alerts for temperature extremes or when it needs service, The thermostat has a color display that even gives you local weather reports.
Seriously cool!!
