7 Best Wireless Thermostats for Smart Homes
We’ve tested dozens of models, so you can confidently choose the perfect smart thermostat that fits your home and budget.
7. Honeywell Home RTH7600D Programmable Thermostat

Energy savings are easy to achieve: set distinct home and away temperatures, use temporary or permanent holds for vacations, and let the thermostat’s Smart Response Technology learn how long your furnace or air conditioner needs to reach the desired temperature. A protective compressor‑delay setting prevents short‑cycling, while alerts for filter changes and low batteries keep the system running smoothly.
