Consumer Reports

Wiring adapter included: Yes.CR’s take: Honeywell invented the precursor to the thermostat in 1886. Today, its spun-out home division called Resideo Technologies offers multiple Honeywell Home-branded smart thermostats. The Honeywell Home T5+ is one of the company’s lower-priced models. It’s not as stylish, but the T5+ offers plenty of utility, with a touch screen, vacation scheduling, geofencing (to turn the temperature up or down when you leave and return home), and voice and app control via Amazon Alexa, Apple HomeKit, Google Assistant, and Samsung SmartThings. It also has a hold function that lets you override scheduling, a welcome feature for unusual days like holidays when you might break from your typical routine. In our tests, the T5+ receives an Excellent rating for manual operation and offers great automation to help you save both energy and money.

Budget Pick

This Honeywell model can’t auto-create a custom Schedule and isn’t as simple to use as other picks, but it works well, doesn’t cost as much, and supports Alexa and HomeKit.
