My smart thermostat wasted more energy than it saved — until I changed this

I bought an Amazon Smart Thermostat expecting lower energy bills. The first month showed modest improvement—maybe a few dollars saved. It was nothing dramatic. I figured real savings would come once the device learned my patterns, so I left the default settings alone and moved on with life. Months passed due to kids, work, and the usual chaos. The savings stayed underwhelming. Then, one Saturday morning, I finally messed with two settings—fan mode and schedules—and everything clicked. It took me ten minutes through the Alexa app since I’d already consolidated all my smart devices under one app. I should’ve done it months earlier.
