I have been using smart devices in my home for over 5 years. While searching for a smart thermostat, I did extensive research.
After looking into many devices, the Honeywell Home T9 Smart Thermostat caught my eye. For $199.99, this hi-tech device guarantees quite an impressive range of smart features that will keep your house temperature perfect.
Although it’s not as elegant as my Nest Learning smart thermostat, the versatility of this Honeywell model makes up for its loss in looks.
Would all these advantages justify such a price tag?
In this Honeywell Home T9 Review, we’ll look at what makes it so special, comparing its smart features with those from other brands to determine if it’s worth the price.
So get comfortable โ we’re about to dive into the world of smart thermostats!
Honeywell Home T9

Pros
- Control temperature in each house room with easy-to-install wireless temperature sensors
- Prioritize temperature in occupied rooms to save energy and money
- Learns how long it takes to heat your home so you always return to a cozy environment
Cons
- Lack of smart radiator valves for individual radiator control
- No wireless installation option
Quick Verdict โ Is Honeywell Home T9 Thermostat Worth the Money?
You may wonder if the Honeywell Home T9 Thermostat is worth the investment. While it’s a little cheaper than some of the competition, like Nest or Ecobee, this smart thermostat still costs $200.
However, if you buy this device, you will soon realize how convenient smart heating technology has become. Here is the breakdown of the top key features offered by this thermostat:
- Bright, easy-to-read thermostat screen with remote temperature sensors that can detect current room temperature
- Remote control via the Honeywell home app that offers Alexa or Google Assistant integration for additional voice control.
- The Smart Response feature requires the help of a room occupancy remote sensor (with a built-in motion sensor), which can sense when a room has been occupied. As a result, it will prioritize and regulate the current temperature accordingly.
- Adaptive Recovery can learn how long your HVAC system takes to reach a desired temperature over time. Hence, it’s ready when you get home because the start time has been adjusted accordingly.
If you still think it’s expensive, consider all the smart features and how much they can save over time. There is no doubt that the device will eventually pay for itself.
While the thermostat doesn’t have self-learning features like Nest, its Smart Response and Adaptive Recover are excellent at not wasting energy, so most people may not notice a difference.
The rectangular design is more classic, yet if you are serious about home automation, the Honeywell Home T9 Smart Thermostat is the device to consider.
Who is Honeywell Home T9 Thermostat For?
Youโll love the Honeywell Home T9 Thermostat if:
- You value comfort and efficiency: schedule and set your desired temperature throughout the house, but with room occupancy remote sensors, heat only rooms in use.
- You have a big house: While T9 has one remote sensor (room sensor), it can support up to 20. Placing one in each room will save a lot on heating costs, mainly when most rooms are not used simultaneously.
- Prioritize adaptability: If you are tired of waking up in a room that is too hot or cold, this smart thermostat has your back. It will adjust the temperatures based on occupancy and humidity levels.
You wonโt love the Honeywell Home T9 Thermostat if:
- Are on a tight budget: You are on a budget and looking for a cheaper smart heating solution.
- Not comfortable with smart heating technology: If you are not comfortable learning smart heating technology, you may not utilize most smart features.
- Lack of Wi-Fi connection: Without a Wi-Fi connection, you won’t be able to utilize most of the thermostat features. So, you may as well stick with the current thermostat.

Design and User Interface

The Honeywell Home T9 smart thermostat doesn’t require a C-wire (common wire) for power. But you can use a C-wire adapter If your existing HVAC system does not have one.
Smart Thermostat is equipped with a white rectangular design. While it isn’t as cutting-edge or modern-looking as something like an Ecobee or Nest – whether this makes any difference depends on your preferences.
The device measures 4.5 x 3.7 x 0.09 inches and has simple yet user-friendly controls. No need to stress about mastering complex controls; this thermostat was made for you, so it’s straightforward to navigate your desired temperatures for heating and cooling.
Build Quality and Material
The Honeywell T9 is crafted with quality materials, guaranteeing toughness and dependability. Its solid construction ensures the thermostat will last, controlling your home’s temperature for many years. Therefore, have no doubts in mind – you’re making a great choice investing in the comfort system of your house.
Honeywell Home App
What would be a smart thermostat without its dedicated app?
Sure enough, Honeywell created an intuitive application that allows managing all features of the T9 device from either at home or while on the go. With the help of this helpful program, one can easily switch between heating & cooling modes, set customized schedules, connect several remote sensors, and adjust required temperature levels wherever they go.
Smart Features Breakdown
Adaptive Recovery

This little guy has a cool feature called Adaptive Recovery.
It checks how long the HVAC system needs to reach the desired temp and then adjusts its starting time accordingly so that everything is perfect when I come home!
Isn’t this awesome?!
This thermostat knows me better than you – no more waiting around freezing or sweating. The T9 got it all worked out without any manual inputs needed.
So, if you hate wasting time waiting for your house to heat up, you must check out the Honeywell T9 and its sneaky Adaptive Recovery feature.
Smart Response
Smart Response pays attention to patterns in daily routine and anticipates temperature changes before they happen.
So it will kick in as soon as you adjust temperatures manually โ ensuring energy isnโt wasted while keeping you comfortable throughout the day. If you plan on cooking dinner, this smart device knows it already and starts ramping up the heat earlier so the kitchen won’t feel cold once ready for cooking.
Geofencing

Are you frustrated when you forget to adjust the temperature before leaving the house?
The geofencing is a great feature, and here’s how it works:
A virtual boundary is set up around your home. It uses your phone’s location and recognizes when you are coming and going from that area. If you leave the boundary, the temp will automatically switch into Away mode. Yet, as soon as you’re nearly back in Home mode, it will start with comfortable room temperatures.
It takes all those worries away if (like me!) sometimes we can be easily distracted or too hectic remembering stuff during our busy day-to-day lives.
Technology like this makes life easier – no more stressing about returning home to a sweltering hot/cold house because now automation does all that work for us!
Voice Control

One thing that you will love is controlling T9 by voice command.
It’s compatible with Alexa, Google Assistant, and Cortana, which lets me make changes without using the touchscreen when feeling particularly lazy.
You can use commands like: “Alexa, set the living room to 72 Fahrenheit. Google, make the bedroom a toasty 75.” It’s like having my assistants on hand, ready whenever needed.
Now I will say, don’t get too carried away chatting with them, or you might start to think they’re listening.
But for quick climate commands, voice control is very convenient.
Temperature and Humidity Control
Managing temperature throughout the house can be a headache, especially if you’re large.
However, the Honeywell T9 can help its remote sensors with temperature and humidity readings. It lets you monitor different rooms, which means you can customize temperatures based on occupancy.
Say goodbye to freezing bedrooms and living rooms. Those extra sets of “eyes” (smart sensors) allow even temps around the home. Not only that, but the system also detects humidity levels so it can make changes whenever needed, ensuring things are never too dry or damp.
Thanks to Honeywell, now thereโs no more ‘no manโs land’ weather inside any part of the home, meaning cold showers won’t happen anymore, nor will soggy clothes due to varying moisture levels.
Automation and Scheduling

Making your personalized climate schedule with just a few taps is super easy.
Have you got an early morning gym session?
No sweat; the T9 will ensure your house feels perfect before you’re out of bed.
Are you working late at the office one day?
It’ll adjust itself to save energy while you’re away.
Life may be unexpected, but when it comes to this Honeywell thermostat, your home’s temperature remains comfortably pleasing no matter what happens. Even if plans change at the last minute – all it takes is a quick voice command or an alter in the app setup.
With automated scheduling and tailored tweaks, this T9 is always ready to work with my always-changing lifestyle.

Sensors have a reliable wireless connection extending up to 200 feet, allowing them to work in basements, attics, or other hard-to-reach areas. Each remote sensor has an impressive 1 year battery life, so you don’t need to replace them often.

Portable Wireless Doorbell
Speak to your guest from the garden with a wireless range of 450 feet.
The Honeywell Home Portable Wireless Doorbell offers an extended range of connectivity that can reach over 450 feet – this makes it ideal for placing the doorbell and chime all around the home and garden, no matter how spacious your space is.
Both pieces run on batteries with a life expectancy of up to 5 years per set.
They’re also portable since they come in handy small sizes; users can choose from 7 LED light colors and 6 preselected sounds for their chimes, making customizations based on style or event easy as pie.

Final Verdict โ Should I buy a Honeywell T9?
I recommend getting the Honeywell Home T9 to replace your old thermostat. Its smart features and capability of automating climate control, as a result, will save you money in the long run.
The Smart Response and Adaptive Recovery are very useful for optimizing temperature automatically. The former increases or decreases fan speed to reach your desired temperature quickly. At the same time, the latter can learn about your house’s heating/cooling needs and then adjust start times accordingly, ensuring that everything will be at your designated level whenever needed.
T9 thermostat can help you save energy while keeping your home warm or cool. It notes how often and when temperatures are adjusted, then makes small changes to optimize its usage over time.
These little changes may not sound too exciting at the moment. Still, cumulatively, they have a considerable impact – reducing your electric bills and cutting down on carbon emissions from power plants.
If you are still unconvinced, look at other smart thermostat alternatives.
Are There Any Other Smart Thermostats?
First on the list is Ecobee 5th Gen Smart Thermostat with voice control. It has a built-in Alexa speaker for when you feel spontaneous and use voice commands to control your smart heating system.
Following closely behind is Google Nest Learning Thermostat, which stands out because of its classy design and intuitive learning abilities. The Nest gets to know your favorite temperature settings over time and assists in conserving power by making necessary changes. It’s the ideal addition for anyone who loves Google products. Plus, it looks like a modern art piece on your wall.
If you’re after an inexpensive smart thermostat that links with Alexa, then Amazon Smart Thermostat is a great option! At only $60, it costs less than other similar products from Nest and Ecobee but still has plenty of clever features included.
