Performance: If you're looking for an excellent smart thermostat, this Honeywell WiFi thermostat is as good as it gets. It has the "learning" capabilities of a smart thermostat, ensuring that your heating/cooling cycles are always accurate. It adapts to temperature and humidity, only turning on until you've reached the perfect temperature and switching off to save energy.

The LCD screen allows you access to the surprisingly simple menu, where you can control every element of the HVAC system. The screen is bright even in a darkened room, making it easy to see the temperature readings at any time. Built with the quality you've come to expect from Honeywell devices, this Wi-Fi thermostat is a high-performance device that will keep your home as cool/hot as you want it!

Features: You can connect to the Honeywell wireless thermostat via the Total Connect Comfort App, available for both Android/iOS phones, as well as tablets and computers. The remote access makes it easy to adjust your system from anywhere, so your home is just the right temperate when you walk in the front door. The app will also send alerts and notifications to your phone, as well as any other devices connected to the network.

The touchscreen can be locked so only YOU can adjust the temperature settings. There is even a 30-second lockout feature that will keep the screen locked while you clean fingerprints off it. Features include: an indoor humidity sensor, large-sized clearly displayed temperature readings, advanced fan control to improve air circulation and reduce heating/cooling costs, energy-saving features, and more.

Price: The $170 price tag may seem high to some, but considering that you get a fully "smart" thermostat that is easy to control, you'll soon realize that it's worth every penny. It's reliable, user-friendly, and a device built to last.
