There are many options currently to choose from when comes to WI-Fi thermostats. Below is a list we have had a postive experience with and our personal favorites. The three Wi-Fi enabled thermostats below are all great thermostats and we have noted some things we like about each. All these thermostats also integrate well with Amazon Alexa as well.
Honeywell RTH9580WF Smart Wi-Fi 7 Day Programmable Color Touch Thermostat
If you like a great looking thermostat with alot of info to show, the Honeywell RTH9580WF is a great choice. We like that it shows current indoor humidity and outdoor temp/humidity all at one time.
ecobee4 Alexa-Enabled Thermostat
The room sensors that work with the ecobee are a very cool feature. The ecobee conditions trouble areas by using a remote room temperature sensor. With the remote room sensor, your system will cool/heat that room until it has reached the desired temperature.
Nest Learning Thermostat 3rd Generation
The Nest is an all around great Wi-Fi thermostat. The Nest can learn your schedule on its on and operate accordingly. Not to mention it is beautifully designed and super user friendly.
