This one Alexa routine shaved my energy bill by 10%

I watched my energy bills climb month after month. My son’s bedroom turned into a sauna every afternoon, while the hallway felt perfectly fine. My thermostat was the problem—it sat in one spot reading one temperature while the rest of the house did whatever it wanted. I started pairing my Echo devices with my Amazon Smart Thermostats, and it changed everything. My HVAC system actually knows what’s happening in each room now. I’m more comfortable, my son isn’t melting in his bedroom, and I knocked 10% off my monthly bills.
