If the Best Smart Thermostat eludes you, then perhaps the Honeywell Home T9 will change your mind. Like its competitors, it’s offering just about every feature you’d want from a smart home thermostat. Needing geofencing is a must, as are voice commands, both traits being the essentials for being the Best Smart Thermostat For Multiple Zones.

Why We Like It – Honeywell Home T9

The Honeywell Home T9 provides just about every essential feature you’d want from a smart home thermostat, like geofencing, voice commands, a touchscreen display, easy installation, and 5Ghz compatibility, for a great price.

  • Easy installation
  • Works on 5Ghz Wi-Fi
  • Fantastic pricing
  • Remote sensors sold separately


When it comes to responding to the changes in your room, the Honeywell Home T9 couldn’t be faster. If you make a change through the app or display, it’s quick to make said adjustments as quick as possible, even when making schedules. This is especially true if you enable geofencing, which kicks in temperature settings whenever you’re home or are arriving. Most importantly: it works with 5Ghz Wi-Fi networks.

Advanced Features

You already know the Honeywell Home T9 has scheduling and geofencing, but what else? With today’s electronics having access to voice commands, like the Ecobee SmartThermostat With Voice Control, it’s natural for the T9 to have them as well. The Ecobee SmartThermostat With Voice Control even allows you to play music via spotify.  If you’re comfortable using Google Assistant or Amazon’s Alexa, the Honeywell Wi Fi Thermostat T9 works with both. This allows you to make adjustments without your phone or ever touching the display.

Ease of Use

Getting around to using the features doesn’t take a degree to understand; in fact, Honeywell makes it really easy. If you prefer a touchscreen display, its menu is simple to understand. Or, if you fancy your smartphone, you can make adjustments through the Honeywell Home app.

Ease of Install

Right off the bat, the Honeywell Smart Home T9 Thermostat really wants to get to work. You can immediately tell by its inclusion of a C wire adapter, like the Glas Smart Thermostat, so that it will be ready and compatible with most homes. It even identifies the kind of HVAC system you have to make the process of installation that much easier, in addition to the intuitive Honeywell Home app to finish the setup.


Being able to quickly install the Honeywell Home T9 has great value on its own. You also get the obligatory Energy Star certification so you’ll save energy usage, saving you some pocket change over time. On its own, the T9 is a great Wi-Fi thermostat, but its value feels more weighty if you drop the extra $30 for the smart room sensors. Even with the price of the sensor, it’s $70 cheaper than the Ecobee4 Smart Thermostat.

Honeywell Home T9 Wrap Up

Even with the extra cost of sensors, the Honeywell Home T9 still squeaks in as a great option for smart thermostats. The fact that it’s incredibly easy to install makes it nearly an instant choice, not to mention 5Ghz Wi-Fi compatibility. And plus, you can get ideal home comfort with or without your input.
