Sense detected fire hazard.

My whole house attic fan has a three way switch in the house. In the late fall I cover the fan with an insulation blanket to keep heat from escaping from the house into the attic.
As a safety device, I installed an on/off switch in the attic as well.
This year I failed to toggle it to the off position.
Sometime this winter the switch in the hall got toggled to high speed. The blanket was keeping the fan from spinning.

Share how you used the Sense app to help. Be specific!:
One of the first things my brand new Sense found was a device labeled Heat 3. It would draw 900 watts for 90 seconds then stop for 20 minutes before repeating. It was doing this 24 hours a day. Besides drawing almost $9 of electricity each month it was degrading my attic fan motor and worse yet, a potential fire hazard. Had the thermal protection shorted to a closed position the fan could have caused a fire in the attic. Sense saved me money and may have saved my home and the safety of me and my wife.
