My $200 smart thermostat ended up costing me $600 in wasted heat last January
I thought the learning feature would pay for itself, but it kept cranking the temp when I was at work and I only noticed after three weeks of $180 gas bills, so now I'm back to a $25 manual dial and wondering if anyone else got burned by these 'savings' gadgets?
Did you see that story about the guy whose smart thermostat kept heating his house because his phone's location tracking made it think he was still home? The thing was, his phone sat on the charger all day so the app saw him "at home" and cranked the heat. I read about a bunch of people with the same problem after firmware updates too, where the schedule just wiped itself and went back to some default. My neighbor had one that would blast the heat at 4am because it decided that was a good time to "learn." A plain dial doesn't have opinions or bugs. It just does what you tell it.
