About The Thermostats

Before we go any further, it’s important that you understand the names of these thermostats so that you can be sure to order the correct model. First, the accurate full name of the Honeywell Wifi 9000 is the “Honeywell TH9320WF5003 WiFi 9000 Color Touchscreen Thermostat.” This thermostat name can be shortened to both ‘9000’ and ‘9320.’ The full name of the Honeywell 9580 is the ​​”Honeywell RTH9580WF WiFi Smart Thermostat.”


These Honeywell 9000 and Honeywell 9580 thermostats are very similar in appearance. Both models contain a 4.5 in. diagonal touchscreen with adjustable color and brightness to best suit your home. The small, rectangular shape offers a traditional thermostat appearance. This style is perfect for residential purposes, and even some office and retail settings.


The Honeywell 9000 and 9580 both work with most heating and cooling systems, and have similar installation requirements. Both of these thermostats require a C-wire for installation. They both run on wall power and do not contain a backup battery for power outages. However, they will save your settings so that the thermostat can operate as normal as soon as the power returns.

The Honeywell 9580 can be installed on your own, while professional installation will be needed for the Honeywell 9000. If you purchase a Honeywell WiFi 9000 and install it on your own, this will void the 5-year warranty.


Both the 9000 and 9580 can be programmed through the mobile app or the touchscreen. Each of these thermostats can display English, French or Spanish languages, as well as Fahrenheit or Celsius temperature scales. Also, they will both allow you to create a 7-day schedule for your home from the touchscreen or app.

The Honeywell 9580 will learn weather conditions and your home’s previous heating and cooling performance. This ensures that your home will reach the desired temperature at the scheduled time with greater accuracy. The Honeywell WiFi 9000 does not offer this feature.

Both of these Honeywell wifi thermostats will continue to function as normal, even if they lose internet connection. This is not the case with certain other smart WiFi thermostats, which must be connected at all times.

Mobile App

Both the Honeywell WiFi 9000 and 9580 thermostats can be controlled via Honeywell’s Total Connect Comfort App. This app is free, which means there are no hidden fees for these WiFi-compatible thermostats.

Of course, you must allow your thermostat to connect to your home’s internet connection for the app to work. Otherwise, you must control everything from the thermostat’s touch screen. The app and touchscreen for both thermostats will display temperature and humidity levels both indoors and outdoors.

The user-friendly app will allow you to control multiple Honeywell devices in one place. This includes both thermostats and security cameras in your home. Or, control multiple thermostats across multiple properties. This allows you to easily monitor your home, even when you’re away.

You can download the app before purchasing a Honeywell thermostat and try it out for yourself in demo mode.

Voice Control

Both the Wifi 9000 and the 9580 are compatible with smart speakers, such as Alexa and Google Home. Integrating your thermostat with your smart home device will allow you to use voice commands to control your thermostat.

However, if you’d like to have the voice control option without an extra device, the Wifi 9000 also offers a built-in voice control feature. This is another key difference between the two thermostats.

Other Added Features

Both of these thermostats also allow you to automatically switch from heat to cool. This can be useful during the spring and fall when the outdoor temperature can change drastically throughout the day. If you don’t want this feature, it can easily be turned off or on in settings.

Another useful feature of both thermostats is the screen lock option. If you have little ones that can reach the thermostat, this can prevent them from tampering with your home’s temperature.

Both thermostats will also send you smart alerts, including a reminder to change your air filter. This is a useful feature if home maintenance tasks like this one often slip your mind. They will also alert you if unusually high or low temperatures are detected in your home.

Features Not Offered

Unfortunately, neither of these thermostats offers geofencing, a feature added in the newer Honeywell Lyric thermostat. This allows your thermostat to adjust automatically when you leave your home and cross a preset threshold, or ‘fence.’ This feature is great for individuals who don’t have a regular daily schedule. So, if this describes you, you may want to consider other thermostat options.

These thermostats are also not compatible with room sensors offered by Honeywell. Room sensors allow your thermostat to sense the temperature and occupancy of rooms throughout your home. This information leads to heating and cooling with better accuracy and efficiency. If you’re looking for a thermostat compatible with room sensors, consider the Honeywell T9 or T10 Pro.


The Honeywell Wifi 9000 retails for about $169 on Amazon. This is slightly cheaper than the Honeywell 9580 which will cost $270 on Amazon However, the WiFi 9000 may come out to the same price when you factor in the cost of professional installation. This is required if you don’t want to void the 5-year warranty that is offered with the Wifi 9000.
