Smart Home Integration Apple HomeKit, IFTTT

The Honeywell Home T9 With Sensor ($ 199.99) is a feature-packed smart thermostat that uses remote room open sensors to ensure uniform heating and cooling throughout your home. Easy to install and manage using the built-in touch screen display, mobile app, or your voice, the T9 offers dual-band Wi-Fi connectivity and works with other smart home devices via IFTTT applets, although IFTTT Trigger options are limited. . It worked flawlessly in our tests, but it lacks some of the extra features that you get with our Editors' Choice, Sound with AQB Smart Thermostat. It's a little more expensive at $ 249, but it has the ability to function as an Alexa speaker, making it worth the extra $ 50.

Design and features

As with the Honeywell Lyric T5 which we reviewed a few years ago, the T9 thermostat avoids the round-shaped form factor previously used by the Lyric thermostat and was popularized by Honeywell's original T86 model. ? Instead, it uses a white rectangular enclosure measuring 4.9 x 3.7 x 0.9 inches (HWD) and has a 3.3-inch (diagonal) color touch display. The thermostat has temperature and humidity sensors and is equipped with a dual band Wi-Fi circuit that allows you to connect to your home network on 2.4GHz and 5GHz radio bands.

The T9 comes with a wireless smart room sensor, a C-wire adapter (for homes without C-wire), mounting screws, a mounting plate, wire labels, and an installation guide. The thermostat is compatible with most standard HVAC systems and includes push-to-connect wire terminals for heating and cooling as well as auxiliary terminals for things like heat pumps and fans.

Like the Ecobee Smart Thermostat With Voice, the T9 uses smart capture sensors to ensure that when people are present, the temperature in selected rooms is equal to the room temperature where the thermostat is installed. It comes with a sensor, but you can buy additional sensors (up to 20 in total) for $ 39.99 each or $ 74.99 for two packs.

The T9 supports Apple Alexa, Google Assistant, and Microsoft Cortana voice commands, as well as Apple Home Kit. You can interact with other smart home devices using IFTTT applets, and it works with Lutron and SmartThings home automation platforms. However, it does not integrate with other Honeywell smart devices such as the Lyric C2 Wi-Fi security camera and Lyric Wi-Fi water leaks and freeze detectors.

The thermostat can be controlled and programmed using its Touch Display or Honeywell Home mobile app for Android and iOS (the same app that controls Lyric smart devices). The app opens on a screen that shows local weather conditions and has tabs for all your Honeywell home devices including thermostats, cameras and water sensors. To open a screen, tap the T9 Thermostat tab, which displays information similar to a thermostat display. At the top of the screen are the current room temperature and humidity readings, and just below that you will find the current target temperature and up / down arrows to adjust the target temperature. Below the screen are the Mode, Fan, Priority, and Schedule buttons. Use the mode button to turn the heating and cooling on and off, and use the fan button to change the fan settings (if the fans are connected).

The Preferences button allows you to select the rooms that will contribute to the average temperature of your home. For example, you can use T9 alone to set the average temperature based on your target temperature, or you can have rooms that average the activity (occupation). The Schedule button takes you to a screen where you can create heating and cooling schedules for days or groups of days. Here you can also enable geofencing to adjust the temperature of the T9 when you (and your phone) are at home or away.

Tap the gear icon in the top right corner to access the settings screen. Here you can manage alerts, set filter reminders, enable adaptive recovery (start heating and cooling quickly so that your home reaches its target temperature as scheduled) and Wi-Fi - Can configure FI settings. The configuration of devices and sensors allows you to check the temperature and humidity in every room where a sensor is present, enabling the sensor to check the battery level and signal strength and to detect movement.

Installation and performance

As with most smart thermostats today, the T9 is easy to install, but if you're not comfortable working with electrical wiring, you'll want to bring in a professional. Start by turning off the power to the circuit that runs your current thermostat. Take pictures of the wiring scheme and later use the included labels to identify these wires. Remove the old thermostat, disconnect the wires, and pull the wires through the holes in the rising T9 plate. Attach the plate to the wall using climbing screws (including) and attach each wire to its corresponding terminal. If your system does not have C-Wire (normal), follow the instructions to install the C-Wire adapter. Once the mounting plate is wired, pull the T9 into place, wait for the thermostat to power up, and follow the instructions on the touch panel.

When prompted, tap Start and select your language. You will then be asked to select a room, unit of temperature (Celsius or Fahrenheit), your type of heat (radiant or forced air) and system type (hot water, steam). After entering all this data, you will be asked to install the sensor, which is as simple as inserting two included AAA batteries and pressing the pairing button. In my test, the sensor was identified in about 20 seconds. I assigned the sensor to a room and followed instructions to install it away from the airways and out of direct sunlight about five feet from the floor.

Next, I was asked to connect the thermostat to my Wi-Fi. I tapped Get Connected, selected my Wi-Fi SSID, entered my password, and connected within 25 seconds. I tapped the Connect app, downloaded the app, created an account, and tap Add Device. I selected the T9 from the list and waited about 10 seconds for the device to be recognized, when the thermostat screen displayed a four-digit code. I entered the code into the app and after 15 seconds or so the T9 registered and the installation was complete.

The T9 performed beautifully in our tests. He responded quickly to temperature changes using the touch screen and mobile app, and he followed my heating schedule without any problems. The remote room sensor followed the T9's target temperature to T and the geo-fencing worked as advertised. Temperature and humidity alerts are issued immediately whenever a threshold is reached.

Alexa Voice Commands also did a good job. I had no trouble setting the T9 to a specific temperature target for a specific time or starting the schedule using my voice, and Alexa always provided the current temperature when asked. My IFTTT applet worked fine when one color camera detected motion to change the target's temperature, but the thermostat had no choice of applet to activate the other device. For example, with the Ecobee Smart Thermostat, when the thermostat detected a certain level of humidity, I was able to create an applet to turn on the smart plug (I had a dehumidifier in the smart plug). No such trigger options have been offered on the Honeywell Home IFTTT channel, although a spokesman has confirmed that more T9 trigger options will be added.

Conclusions

Honeywell Home T9 Smart Thermostat Sensor makes it easy to maintain the same temperature throughout your home. You can add up to 20 remote room sensors that can help reduce heating costs by telling the T9 if a room is occupied or empty. The thermostat is easily controlled from your phone using Alexa, Cortana, or Google Voice commands, or the Honeywell Home mobile app. While the T9 will work with other smart devices using IFTTT, Apple's choices are limited for now, but more will be added in the near future.

If you want a smart thermostat that does more than control your heating and cooling system, check out the Ecobee Smart Thermostat with Sound. Not only does it support most popular voice platforms, but it also acts as an Amazon Alexa device that streams music, gives you the latest news, and supports Alexa calling and messaging. And it does everything that the Amazon Echo speaker does. It is also very easy to install and works with other smart devices and home automation platforms. As such, it is the choice of our editors for smart thermostats.
