That led many customers to ask the question: Does Honeywell T9 Thermostat Control Humidity?

Can the Honeywell T9 control humidity?

The Honeywell T9 Thermostat can measure humidity but not manage it. The thermostat and the T9 sensor that comes with it can both detect humidity to give you a better picture of what’s going on in your house.

How to Check Humidity Levels on Honeywell T9 Thermostat

To monitor your home’s humidity levels, you can utilize the app or the thermostat device itself.

Using the Thermostat device

Follow these procedures to see the humidity level on your thermostat: 

  1. Go to your home’s central thermostat. 
  2. If necessary, tap the screen to brighten the background. 
  3. A little water droplet symbol appears over the large temperature number. 
  4. The humidity percentage is shown by the number next to the drop symbol.

Using the Honeywell Home App

You do not have to physically get up and check. How about you do it from the comfort of your bed?

This will require a mobile device with the Honeywell Home App installed and logged into your account. If you do not have the app, you can download it from your App Store or Google Play Store.

  1. To access the settings page, hit the gear icon in the right corner.
  2. Select “Devices & Sensors” 
  3. Locate the sensor you want to inspect by clicking its name. 
  4. The temperature and humidity of the room where the sensor is positioned should be displayed.

You can purchase and add up to 20 sensors through your home. This allows you to have a more significant idea of the humidity in every room in your home. 

I find this especially valuable in bathrooms. For instance, after taking a hot shower, it is essential to leave your bathroom door or window open to avoid the growth of mold. Thus, having a monitor can be beneficial in various areas.

Other areas such as laundry rooms, basements, and kitchens could also benefit from having monitored humidity. But in reality, all your rooms should be monitored.

How to monitor the humidity in your home using the Honeywell T9 Thermostat

Below you can find tricks and tips to monitor and ensure your home is not too humid.

  •  Install humidity sensors in each area of your home to help you keep track of the humidity levels. If you have concerns about your home’s humidity or thermostat, contact an HVAC specialist. 
  • In the summer, set the thermostat at 72-78 degrees. When you’re not at home in the winter, set the thermostat to roughly 68 degrees. 
  • Select the “auto” option on your thermostat to allow the air to dehumidify naturally. And when you’re not at home, program your thermostat to adjust the temperature. 
  • In the summer, maintain a humidity level of 40 percent to 65 percent. While in the winter, make sure the humidity level is at or below 40%. 

Why is monitoring critical?

Despite the fact that the Honeywell T9 thermostat does not control humidity directly, the sensing tool can assist you in ensuring that your humidity is at the proper level.

Too little and too much

Humidity is a two-way street. High humidity levels can lead to the formation of mold, mildew, and germs in your house. Mold can potentially harm your air conditioning system as a whole. 

In rainy and hot summer months, consider purchasing a dehumidifier if you are concerned about the humidity levels in your home. They will aid with the removal of moisture from your home and the maintenance of proper humidity levels. 

Too much humidity is not good; it can lead to mold growth and other issues inside your home. Now you might think that high humidity is bad; therefore, I should make it as low as possible. Wrong!

The same applies to too little humidity; it can put you and your home at risk. Static electricity, dry skin, lips and hair, scratchy throats and noses, itching, and chapping are all symptoms of low humidity. 

Body moisture evaporates so fast at low humidity levels that you feel cold even at higher thermostat settings. Your house is affected as well. Woodwork and furnishings can be damaged by low humidity.

To avoid this, consider acquiring a humidifier if you have difficulties with chilly air and low humidity in the winter. It will reintroduce moisture into the air, making it seem more pleasant and warm.


The Honeywell T9 Thermostat is a worthy investment that can further give you a bigger picture of what is going on inside your home and keep you alerted to the humidity of the different rooms in your home.
