Expert Reviews


What reviewers liked

It works perfectly with any system type and can view local weather from the web. The display is bright and therefore accurate.
-
The universal application allows it to be used with heat pump and conventional systems. Four periods per day can be separately programmed seven days a week.
This is a universal thermostat that supports up to two stages each of heating and cooling including heat pump and hydronic 24V systems.
The backlit digital display makes it easy for you to use it. You can either use the device with your multi or single-stage systems.
This model is extremely similar to traditional programmable models — and is therefore plagued with similar difficulties when it comes to using them. After setting the date and time using the arrow keys., the screen flashes "Wi-Fi Set-Up" with no clear indication of what to do next, definitely requiring us to consult the manual
One thing we love about Honeywell is that they provide a wider variety of integrations than most other thermostats. As automated homes become more popular in the coming years, we expect Honeywell to expand their integrations even more.
Easy to set up and work. Can connect with personal assistant devices like Alexa for voice control over the wireless connection.
It’s easy on the budget, the app has come a long way since the the thermostat’s introduction a few years ago, and it’s got all the basic stuff you’d expect from a thermostat. There’s no need to worry if your power goes out – it’ll remember your settings.
The display is digital and the thermostat is made of plastic, it has a simple design and it is not confusing to figure out how to use it. The display is backlit which means when you push any of the button display will instantly wake up.
Additionally, you can also use a computer or even your voice assistant to control the temperature.
In other words, the Honeywell Wi-Fi Thermostat brings you the most value at the most affordable price.
For just $79, you get the thermostat that will help you become a more efficient home.
Programming is one of the most important features, and this unit is pretty much standard in that respect. You have the option for 7 day programming so you can pre-set your schedule for each day of the week, and within each day you can choose up to four different periods. It also comes with a very handy pre-programmed energy saving schedule which helps save money on your bills.
Another great feature of the Honeywell RTH6580WF is its default built-in schedule. This helps a lot of users get started. You can ditch the defaults completely and make your own, or make a few changes so that it matches your schedule.

What reviewers didn't like

Some users have a difficult time getting the thermostat to connect to WiFi at initial setup. To help connectivity, set up the thermostat using a smart device and the app.
Not the most stylish, average install
There is no humidity sensor. If it cannot measure humidity, then do not expect it to detect when you are home (activity sensor) or when you are approaching it (proximity sensor).
Lacks some convenience features other units have.
The only people who would be disappointed in this thermostat would be those who wanted something flashier like a Nest
To install this thermostat you need to have a C wire because it is the primary power source for your thermostat.
It is not, however, compatible with electric baseboard heat.
This thermostat cannot do everything that some of the other smart thermostats can do that are currently available, but for the price, it’s worth it.
With this one, you have to make sure your system has a ‘C’ wire (more on that on this page) and you must also make sure that your system is 24 volt
The thermostat itself is difficult to control; needs app for ease of access
