Did a quick search and didn't see a recent thread (or any thread for that matter) on smart Thermostats and/or smart home accessories.

Being in Central, OH and a Columbia Gas customer, they are currently offering a $90 instant discount for smart Thermostats that covers the Nest 3rd Gen, Nest E, and Ecobee 3 and 4.

Due to my HVAC's dual speed fan, I can't use the Nest E. Has anyone used a nest or ecobee? What are your impressions? Most importantly, did it save you money on your utilities?

I believe that I'm leaning towards the Nest Gen3
