Honeywell Home T9 Smart Thermostat

Smart thermostat

The Honeywell Home T9 Smart Thermostat allows you to control the temperature remotely through the Honeywell app. Furthermore, the room sensors optimize comfort by detecting humidity and making adjustments to rooms where more people gather.  Features include:

Hardware or software requirements

The thermostat offers guided assistance during installation. How it works is you turn your home’s existing thermostat off at the fuse box. Next, remove its cover. It might involve gently pulling at its base or removing screws. This thermostat uses C-wiring. If your thermostat does not have it, there are other options you can do using this guide.  From here, the Honeywell app shows you how to connect everything. However, if you are unsure about installation, you can reach out to a Honeywell specialist, who’ll be happy to help. Moreover, the thermostat allows you to control everything through your home’s Wi-Fi connection. Your connection can either be 2.4 GHz or 5.0. 

The Honeywell App provides simplicity

Once installed, you’ll be able to take advantage of all the thermostat’s unique features. Start by becoming familiar with the Honeywell App. The app is free to download through Google Play or Apple App Store. After installing it, the app walks you through the setup. Using your home’s Wi-Fi connection, it can detect the T9 in your home.  The home app uses geofencing. It is a nifty tool that notices when you come home or leave for prolonged periods. It is beneficial in that the thermostat can set the temperature higher when you’re away, then lower it as you arrive home. In turn, you receive a healthy mix of efficiency and comfort. And you could reduce your energy bills by up to 10%.  The app also sends you notifications when it detects a room is too hot or cold. And if your home’s air filters become dirty, it even sends you a reminder to change them. 

Smart sensors balance comfort and efficiency

Using the base T9 thermostat alone allows you to control the temperature of your whole house. In saying that, it won’t provide the highest level of comfort or efficiency. Some rooms become warmer due to more sunlight exposure, higher occupancy, or they tend to be more humid. It is where these sensors come in handy. Best of all, the Honeywell T9 Smart Thermostat offers scalability from one to 20 sensors. It makes it suitable for a wide variety of house sizes and floor levels.  Also, once you install the sensors in the rooms you want, you can control them through the Honeywell App or the thermostat’s interface. To demonstrate, if you are hosting a game night, you can adjust the temperature in the living room to be cooler to remove the humidity and extra heat.  At the same time, you can keep your bedroom, kitchen, and other areas of your home at a higher temperature. That way, your home’s air conditioning unit does not have to work as hard, giving you more efficiency and a lower energy bill.

Potential security issues

Smart thermostats like the Honeywell Home T9 can be vulnerable to hacking. To mitigate risk, refrain from using the same password for everything, including your Wi-Fi access. That way, it makes it more difficult for hackers to access a backdoor to your internet through hubs like thermostats.

Current pricing

The Honeywell Home T9 Smart Thermostat retails for $169.99. You can add one room sensor for $199.99. You can also buy the thermostat with a C-wire adapter for $199.99.

Customer support

Honeywell provides a support hub on its website, where you can also access how-to videos and troubleshooting. If your problems are more extensive, they even include a list of retailers nationwide carrying their products.

Bottom line

The Honeywell Home T9 Smart Thermostat is a wise addition to your home. And when you pair it with the room sensors, you receive the pinnacle of comfort and efficiency. While the price might be high (the thermostat and one sensor retail for $200), it could be well worth it when factoring in the geofencing, energy audits, and possible energy savings you receive.
