The Honeywell T6 Pro Z-Wave is made for people who want a thermostat that can be controlled locally through Z-Wave. It’s a great choice for people who have a Z-Wave smart hub like SmartThings, Hubitat, or Home Assistant (HA).
This thermostat lets you precisely control the temperature, set schedules, and access it from anywhere using Z-Wave. It’s a great choice for people who want to automate their homes without using cloud-based services.
The Emerson Sensi Wi-Fi thermostat is smart and easy to use. It links via Wi-Fi and works well with Apple HomeKit, Amazon Alexa, and Google Assistant. If you want an easy-to-use thermostat that’s also easy to set up, this is a good pick.
The Sensi relies more on the cloud than the T6 Pro, but you can still handle it locally through Apple HomeKit as long as you have a C-wire for power.
It’s easy to add the T6 Pro Z-Wave if you already have a Z-Wave hub, like SmartThings, Hubitat, or Home Assistant. But if you don’t already have a Z-Wave hub, you’ll have to buy one separately, which makes the whole process more expensive and difficult.
If you don’t have a C-wire, the T6 Pro can run on batteries, which is a big plus.
If you have a C-wire handy, the T6 Pro can use it to get power all the time, which is what you should do for better performance.
Setting it up is easy, but you need a C-wire for HomeKit.
One of the easiest smart thermostats to set up is the Emerson Sensi Wi-Fi, especially for people who already have a C-wire. However, if you want to use Apple HomeKit, you will need a C-wire, which may mean more work when installing.
It can be a hassle to connect a C-wire to your HVAC system, requiring you to either purchase an adapter or run a different wire from your heater. You can also use it without HomeKit and still use the Sensi app or voice helpers to control it.
The Honeywell T6 Pro Z-Wave and other Z-Wave devices don’t need cloud services to work, which makes them more stable and safe. As long as your thermostat is connected to your local Z-Wave network, it will still work even if your internet goes down.
Best for:
What the Emerson Sensi Wi-Fi is better for people who want to use a mobile app to connect directly and want it to work with Alexa, Google Assistant, and HomeKit. For online viewing, though, you do need to be connected to the internet.
Best for:
People who want to automate their homes with Z-Wave love the Honeywell T6 Pro Z-Wave. It works well with Home Assistant and SmartThings, and you can handle everything from your phone. Some users, though, say that the best speed comes from setting up the Z-Wave network correctly.
Pros: ✏ Great power at home ✏ Doesn’t depend on cloud services
It can be used with batteries or a C-wire.
Cons: ✖ Needs a Z-Wave hub ✖ Doesn’t have a mobile app
The Emerson Sensi Wi-Fi thermostat gets great reviews for how easy it is to set up and how well the mobile app works. But people who don’t have a C-wire sometimes find it hard to use HomeKit.
Pros: It’s simple to set up, it works with most smart home platforms, and it gives you reports on your energy use.
Cons: ✖ For HomeKit, you need a C-wire ✖ relies on control from the cloud
✠ You have a Z-Wave hub (like SmartThings, Hubitat, or Home Assistant).
✠ You want local control that doesn’t depend on the cloud
✠ You want battery-powered operation (if you don’t have a C-wire)

The Honeywell T6 Pro Z-Wave and the Emerson Sensi Wi-Fi are both great thermostats, but which one you should choose relies on your smart home system and how you set up your power. The T6 Pro Z-Wave is the best choice if you want to handle your home without being connected to the internet. The Sensi Wi-Fi is better if you’d rather control your Wi-Fi from your phone.
