Friday a friend of mine received a notification from his Smart Thermostat:
Alert! Loss of Cooling
Your cooling equipment is not adequately cooling your home, and the temperature inside your house is at least 5 degrees higher than your thermostat temperature setting. This problem can be caused by the following:
- A door or window may be open
- Power to your cooling equipment may be lost
- Your cooling equipment may not be working properly
Evidently beyond the gizmo’s ken was the actual cause of the situation: it was 109 degrees Fahrenheit outside, tying a record for the date, and only four degrees short of the all-time — well, since 1891 anyway — record for this town.
In my own house, with classic/antiquated (choose one) equipment, the gap was 9 degrees.
