What home thermostat do you have?

We have the ecobee3 (w/ Alexa) downstairs and the ecobee3 lite upstairs. I really like all of the features and options for tailoring your AC/heating that the ecobee provides. You can tweak lots of parameters about how it behaves. You can set Home, Away, Sleep comfort settings and then use those with the scheduling app. There’s also a dashboard that you can check to see exactly when it kicked on, what the temp inside and outside were, how long it ran for, etc.
