Check Out Some Best Wi-Fi Smart Thermostat

Ecobee4 Smart Thermostat With Built-In Alexa

The original smart thermostat maker creates a solid product with a sleek design that allows for pre-programmed energy usage.

Supports multiple smart assistant platforms, offers HomeIQ so you can track energy usage, and comes with sensors to automatically adjust the temperature based on room occupancy.

This also could have easily been our #1 pick so it is an honorable mention.


  • Supports wide range of smart assistant platforms
  • HomeIQ for accurate energy usage tracking
  • Room sensors for precise temperature adjustments


  • Poor tech support
  • Must purchase additional sensors for other rooms
  • Can stay offline if WiFi signal is interrupted

Many people may know ecobee as the original smart thermostat.

The ecobee4 comes with a room sensor and a slick full-color touchscreen.

The brand promises quick installation that shouldn’t take more than 30 minutes to complete and a kit that includes an extender just in case your existing wiring doesn’t include a C wire.

Either through the proprietary app, the touchscreen, or a smart assistant, you can program temperatures in advance.

You’ll love the wide range of smart assistants that are supported by ecobee. Choose from Alexa, Microsoft Cortana, IFTTT, Google Assistant, Apple HomeKit, Samsung SmartThings, and Wink.

A bonus is the HomeIQ feature which logs energy usage and can be accessed through the app. The ecobee4 also comes with one smart sensor which can be placed in a room for precise temperature control

Based on temperature readings and occupancy, the temperature is automatically adjusted for your comfort.

Honeywell Home RCHT8612WF T5 Touchscreen Smart Thermostat

Being budget-friendly doesn’t have to mean limited functionality and Honeywell proves that point with this smart thermostat.

It easily earned our best budget thermostat rating. From multi-day programming, multiple smart assistant device support, geofencing technology, and AI functionality, Honeywell’s T5 has more than enough to improve your energy efficiency.


  • Multiple smart assistant device support
  • Power extension for C wire
  • Utility rebate support


  • Lacks a G wire extension
  • In-app configuration can be difficult
  • Proprietary app functionality is inconsistent

You might think that a limited budget means you shouldn’t expect too much from a smart thermostat. But Honeywell proves that’s just a myth with their T5 smart thermostat.

First, you’ll love the sleek design which will make your home feel modern as soon as it’s installed.

Preprogram up to seven days of temperatures and take advantage of the alert system that notifies you when it’s time to replace your air filter or if indoor temperatures are extreme.

For the tech-obsessed, you’ll like that multiple smart assistant devices are supported.

Alexa, Apple HomeKit, and Google Assistant are all supported. Geofencing allows you to automatically adjust temperatures based on your phone’s proximity to your home.

Honeywell Home Wi-Fi 7-Day Programmable Thermostat

A straightforward smart thermostat that lets you program temperatures for a full week with four periods per day and comes with a G wire extension to provide C wire support.

This is our top pick. Tech-savvy users will enjoy Alexa compatibility, the proprietary app, and enhanced functionality like real-time weather.


  • G wire extension
  • 7-day programmability with 4 periods per day
  • Supports multiple smart assistant platforms


  • Using G wire extension removes fan controls
  • System can override temperature presets for heating
  • Inaccurate temperature readings below 40 degrees Fahrenheit

The Honeywell Home Wi-FI 7-Day Programmable Thermostat makes our top pick because it offers the best of both worlds whether you’re tech-savvy or averse.

A simplified LCD screen and touchpad are ideal for those used to older style thermostats.

But tech-savvy fans will love that you can set a seven-day program and even further program each day into four periods for precise temperature control throughout the day.

This Honeywell thermostat works with WiFi which means you can also remotely manage the temperature and programs through either their proprietary app or by connecting it with a range of smart home assistants
