The Honeywell RTH6580WF is a very affordable smart thermostat that offers advanced features. Its familiar interface and large, easy-to-read display is simple to use and looks unassuming. It offers extensive compatibility with HVAC systems, keeps working during power failures, and adjusts for daylight savings time.


This Nest thermostat comes with a number of useful features. Its Smart Response Technology ensures energy efficiency by learning your preferred settings and optimizing operation to deliver the right temperature at the right time. The 7-day programmable functionality allows a high range of customization. It offers few more benefits like voice command with Alexa and an accompanying mobile app.

Be sure to check compatability with your own HVAC system before making any purchase.


This Honeywell thermostat is not compatible with 110-volt or greater systems such as electric baseboard heat. It has no reminders to tell you that you need to change your filter.

Like any other thermostats, this should be located on an inside wall, about five feet up from the floor and must be protected from any liquids or excessive moisture. If you need help installing the thermostat, contact a professional.

Note that a C wire is required and is the primary power source.


Overall, the Honeywell RTH6580WF is a solid thermostat available at a very reasonable price. It may not look sleek or particularly modern, but it offers easy controls and basic smart features. Its voice command functionality makes it a good fit for those used to Alexa or Google Home. While it doesn't send smart alerts (around filter changes or furnace usage), it can save users quite a bit on energy compared to traditional systems.

If you're looking for an affordable, practical smart thermostat with basic functionality, the Honeywell RTH6580WF might be just what you're looking for.
