The Honeywell T9 Thermostat is a smart thermostat that will help keep your house as warm or as cool as you like it all on its own. Its advanced technology offers users many different aspects that the average thermostat can not provide. Of course, as advanced as this thermostat is, you may be wondering if it requires Wi-Fi to work.

The Honeywell T9 Thermostat can work without Wi-Fi, but many smart features will be limited as opposed to if the device was connected to a strong Wi-Fi connection.  

One of the main selling points of the Honeywell T9 Thermostat is all that it can do when connected to Wi-Fi, but if you do not have Wi-Fi, know that it is still capable of performing basic functions. Continue reading to learn more about what works and what doesn’t when the Honeywell T9 Thermostat isn’t connected to Wi-Fi.

Does the Honeywell T9 Thermostat Work Without Wi-Fi?

The Honeywell T9 Thermostat is a smart thermostat that can control the temperature in your home automatically, be controlled through voice commands, accessed through your smartphone, create schedules, and much more. But can you still use these same features without the device being connected to Wi-Fi?

Your Honeywell T9 Thermostat will still work without Wi-Fi, but it will only provide you with the basic functions for the most part. If you are looking to use this thermostat long-term without Wi-Fi, there may be a few more inexpensive options on the market that provide you with the same things that the Honeywell T9 does without Wi-Fi.

However, if you are having issues with your Wi-Fi or do not have Wi-Fi but are planning to get it soon and are wondering if this thermostat will still heat and cool your home for the time being, the answer is yes!

Features Available on Honeywell T9 Thermostat Without Wi-Fi

As mentioned, this thermostat’s capabilities will be limited without Wi-Fi, but it will still cover the necessities. The features that still work without Wi-Fi include:

  • Heating
  • Cooling
  • Sensors

Heating and Cooling Settings

The most important thing that will definitely still work without Wi-Fi with the thermostat is heating and cooling. You do not need to worry about the thermostat completely shutting down and not working at all if you are not connected to Wi-Fi.


The sensors are one of the best and most interesting things this thermostat offers, so it is really convenient that they can work without Wi-Fi.

The Honeywell T9 Thermostat can connect to multiple sensors, up to 200 feet, that you can place in each room in your home, and they will be able to detect if anyone is currently in the room or not. If someone is in the room, the sensors will signal to the thermostat to make the temperature in that specific room optimal for people in it.

Features Unavailable on Honeywell T9 Thermostat Without Wi-Fi

While the basics are covered, it is still nice to have access to everything this thermostat offers if you are paying for it. Without Wi-Fi, you will miss out on many things that make this thermostat worth the price. The features that you will not be able to access without Wi-Fi include:

  • Geofencing
  • Humidification levels
  • Shortcuts
  • Alexa/Google Assistant sync


While you can always set your thermostat to home or away through the app while your thermostat is connected to Wi-Fi, this thermostat now also offers geofencing.

Geofencing is the capability to have your phone tracked by the thermostat so it can detect whether you are home or not. That way, you don’t have to remember to set your thermostat to home or away; it will automatically know on its own.

Humidification Level Detection

Another interesting feature that can only be accessed if you have Wi-Fi is the thermostat’s humidification level detection. The thermostat can pick up on humidity in your home and accordingly adjust the climate.


Without Wi-Fi, you will not be able to access all of the shortcuts the Honeywell T9 Thermostat has to offer, such as schedules, smart responses and alerts, auto home and away mode, and more.

Alexa/Google Assistant

The Honeywell T9 Thermostat can even connect to your Alexa or Google Assistant for you to control the thermostat through voice commands. However, this will be unavailable to you without Wi-Fi.

In Summary

The Honeywell T9 Thermostat has so much to offer, which is why it is worth the price. However, its features cannot be used without connecting your device to Wi-Fi. You can still use your Honeywell T9 Thermostat to heat and cool your home without Wi-Fi, of course, but that is about all you will be able to do.

Therefore, if you plan on using the Honeywell T9 Thermostat long term without connecting it to Wi-Fi, it may be in your best interest to install the average thermostat to save a few dollars.
