We're trying to get our energy usage under control and thanks to a smart me= ter we can how see our household energy usage at 15 minute increments. Wha= t I'd like to do is find a home thermostat that'll keep logs of when the HV= AC system comes on and goes off plus possibly a log of the temp and humidit= y. Our current thermostat has all this info on screen but there's no log = per say that saves it.=20
Does something like this exist? I can't help but think someone has created= one with a Wifi connection or possibly USB port to save the logs to since = this would be invaluable information for any home wanting to cut costs.
Thanks --
