Honeywell Home T5 Smart Thermostat review

The T5 covers the basics that save money for a little over $100. Geofencing uses your phone's location to hold off heating or cooling until you are on your way home, and Smart Response learns your routine and how long your system takes, so the house reaches the set temperature on time. You can follow a 7-day, 5-2 or 5-1-1 schedule instead. Monthly home energy reports compare your use with similar homes and suggest ways to cut it, and Honeywell supports utility rewards programs for extra savings. It works with Alexa, Apple HomeKit and Google Assistant, and it handles up to 2H/2C conventional and 3H/2C heat pump systems. The limits: there is no built-in occupancy sensor, geofencing depends on everyone's phone, Wi-Fi is 2.4 GHz only and the warranty is 2 years. Check whether you need Honeywell's C-wire adapter before you buy. We compared documented features and published prices.
