Has a few requirements, but for Baltimore gas and electric customers already enrolled in peakrewards, they are giving away Ecobee3 Lites.
To qualify, you must meet the following requirements:
Be a homeowner and primary resident
Be an existing PeakRewards A/C program participant
Have a secure Wi-Fi internet connection at your home (hot spots aren't eligible)
I already had a full blown ecobee3, so i didnt grab one, but wanted to share the wealth.
