The Honeywell T6 Pro WIFI Thermostat is a great smart thermostat that offers a clean user interface for easy use. The device connects with a building's HVAC system, and it can be programmed for automatic operation based on a set schedule. Remote operation is done through a WIFI connection.
Some of the best aspects of the Honeywell T6 Pro WIFI are its ability to be used with Apple HomeKit and the Honeywell Home App. This allows the user to control the device remotely from virtually anywhere in the world from their smartphone. Honeywell has also made initial set up of the thermostat extremely simple. This will give new users an easier experience in getting started with the device and setting up its initial settings and configurations.
Please note that Honeywell also offers the Honeywell T6 Pro Z-Wave Thermostat. This is essentially the same thermostat, except it communicates across Z-Wave as opposed to WIFI. Each communication path offers certain advantages that should be considered before making a decision. The primary selling point of the WIFI version is that it can integrate with Apple HomeKit. This is huge for iOS users who have set up a HomeKit network of smart devices. Many users will also appreciate the ability to use the WIFI version with the Honeywell Home App.
But there are some benefits to choosing the Z-Wave version instead. Only the Z-Wave version offers local control through an on-site security panel. Additionally, the WIFI version cannot be used with full smart scene control through Total Connect 2.0. This is only possible with the Z-Wave version. That means you are limited in your ability to use security actions as triggers for automated scenes on TC2. Although you can always build scenes in HomeKit, they are a bit more limited in the number of trigger points you have available. Finally, the Z-Wave version does not require a C-Wire, and it can rely on batteries for power. The WIFI version requires the C-Wire, which can make it more difficult for DIY users to set up. But if you want to use your thermostat with Apple HomeKit, this is the version to choose.
Note: This is the WIFI version of the T6 Pro. The Z-Wave version is linked above.
