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.

Compatible with smart home systems

This thermostat pairs with several home systems like Google, Cortana, and Amazon. However, it does not support integration with the Apple HomeKit. For the ones it does integrate with, it offers voice-command capabilities. It adds one more convenience element to optimizing comfort. 

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 buythe 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. 

Honeywell Home T9 Smart Thermostat FAQ

How long does the warranty last?

Honeywell offers a two-year warranty on its T9 Smart Thermostat.

How can it lower my energy bills?

When paired with a room sensor, it detects when people stay in one room or pass by to another. From there, the thermostat makes adjustments for rooms occupying more people while keeping other rooms in your home at the same temperature. Because of this focused approach, your home's HVAC will not have to work as hard (provided it is in peak operating condition), resulting in lower energy bills. 

What's the difference between the old and new models?

The old model did not support up to 20 sensors or have the capability to prioritize multiple rooms. Meanwhile, the new one has both of these abilities and can support the 5.0 GHz Wi-Fi. 

Does my utility offer a rebate for buying one?

Honeywell makes it simple to find rebates for buying the T9. You can discover local ones near you (if applicable) using the Utility Rebates Program on Honeywell's website.
