I received a flyer in the mail from dte energy (Michigan based gas/electric supplier). They are currently offering a free ecobee3 smart thermostat if you let them do the free in home energy consultation. They said you can sign up for it online via their website or call 1866-796-0512. I could not find any mention of the free thermostat on the website but when I called in the rep 100% assured me it was free and no strings were attached. I am a gas only customer so I am not sure what you need to do to qualify. It only took a few minutes to setup, however due to the popularity of the offer, they are booked up quite far (I have a Dec 6th appt and I called the day after I received the mailer on Tuesday). The rep also said they have quite a few of them in stock so chances are good they will have them, even a month or two out.
