We recently installed stone floors downstairs along with associated in-floor heating. We chose stone for the look / durability, but also hoped that the additional thermal mass would help keep the house cooler in the summer since we have warm-hot days and cool nights most of the year.

I was therefore surprised to see a new device show up this morning, that the crowdsourcing picked to be a floor heater. Especially bad given that the air conditioner is running a bit during the daytime during this season. I took a quick look at the Sense device waveform, then because Sense thought it was floor heater, consulted the NuHeat app to find that my Guest Bedroom heat usage waveform matched exactly ! But why was it on ? User error – the Guest Bedroom nighttime setting was 68 degrees ! I was quickly able to adjust the thermostat down….
