Best Z Wave Thermostat For Smart Homes

Z Wave thermostats offer homeowners the ability to connect and sync controllers using a very low bandwidth.

We like the Honeywell RTH9580WF​ because it can be controlled using a mobile device.

It's important to note that, at their core, many other Z Wave tools are not Wi-Fi enabled; rather, they can function on a much simpler platform.

Each of these units works in conjunction with a Z-wave controller, which can be run via Wi-Fi. While manufacturers offer different features, Z Wave technology is a unique and dependable method of data transmission.

In this guide we will look at and compare some of the best Z-Wave thermostats to help you choose the best model for you and your smart home in our Z Wave thermostat reviews.​

Z Wave Thermostat Reviews

Honeywell Z-Wave Smart WiFi Enabled Thermostat

The Honeywell Z-Wave unit offers Z Wave control without needing access to a common wire, thanks to the built-in wire saver.

This means you can have low-frequency Z Wave control power without needing to make any changes to your home's electrical service or capacities.

This unit is easily programmed via the touch screen display or over Wi-Fi using a mobile phone device and will also display the condition of your HVAC system.

The Honeywell Z Wave controller offers a large screen with several programming options. This unit will let you know when it's time to change the HVAC filter and if there are any concerns regarding your HVAC system.

Like all Z-Wave technology, the Honeywell thermostat can be controlled via Z-Wave hub such as Mi Casa, Alexa, Wink or SmartThings.

While the Honeywell is programmable, it's easily overridden. If you program your thermostat to keep your home cool overnight but need to change that for guests, you can quickly override the programming with a single touch, and then revert to the original programming at a later date.

GoControl Z-Wave Thermostat

The GoControl Z-Wave works with the Alexa program for total home voice control. You will need to purchase the Alexa system separately.

This thermostat will run two stage heating and cooling settings on a standard HVAC system and three stage heating and two stage cooling setting on a heat pump HVAC system.

The GoControl Thermostat can be used with a smart home hub or can stand alone. Should your smart home hub fail, this unit can be manually set and will maintain the last manual setting.

You can make this unit as simple or as complex as you need; back-up power includes 4 AA batteries, or you can simply tie the controls to your home's power system.

Programming this unit can be done on-screen or from your smart home tool. The display screen is very simple, showing only the current temperature, temperature range and whether you're in heating or cooling mode.

The screen size is simple and small, but if you need to go deeper into the programming, there are several menu options for more detailed scheduling and programming.​

2gig Z-Wave Programmable Thermostat

The 2gig Z-Wave CT100 is recommended to pair with the Samsung SmartThings Hub for wireless home control.

It offers remote control and can be programmed for the whole week to save energy.​

However, Z wave units should work with any Z wave controller. Review your smart home controller recommendations before purchasing any Z wave thermostat.

The 2gig thermostat will allow up to four stage heat control, so if your HVAC system offers that much flexibility, you can take advantage of all the settings for extreme comfort no matter how cold it gets!

This unit is easily programmable from the thermostat and offers back-up power to save that programming with AA batteries.

The 2gig thermostat can easily be run with any smart home controller, or you can set it manually. There's also a remote for convenience. This thermostat is backlit for easy viewing; simply touch the screen and you'll be able to see the display.​

Z-Wave Technology

Z-wave technology functions within your home through a smart home hub such as Alexa, Mi Casa or SmartThings.

Smart home hubs are Wi-Fi enabled, so you can check them on-line or via a phone app to make sure the items in your house are functioning within normal usage ranges.

Z-wave chip technology is available on many electronics in the home.

As previously stated, Z-wave products function on a very low bandwidth. You can't check in directly with your thermostat via Wi-Fi, but by accessing your smart home controller, you can get a status update on many items in your home.

If you have an existing smart home hub, you should plan to purchase a thermostat that will mesh well with your existing system. Z wave protocol stacking for smooth connection is generally fairly simple; Z wave units should work well with any controller.

However, if your smart home hub manufacturer recommends a specific brand or installation procedure, you can save yourself connection and programming headaches by purchasing the best brand for simple connection.​

A Note About HVAC Systems

Single stage cooling systems are either on or off. Two stage cooling systems can run at high intensity or low intensity depending on your need. Depending on your HVAC system, you may have more cooling or heating stages.

Some programmable thermostats will not work with multi-stage HVAC systems.

It's important to review the capabilities of any thermostat before swapping out the one you currently have. Additionally, a well-functioning thermostat is crucial to the safety of your home and family.

Electricity is not fussy; it will happily run a charge through anything or anyone it comes in contact with. Consider hiring an electrician for this crucial project.

Final Thoughts

There are a number of Z wave thermostats on the market, and depending on your smart home hub, you may be inclined to purchase the unit recommended for easiest connection to your hub. However, the best Z wave thermostat is the one that's easiest to read and adjust.

We think the Honeywell Smart WiFi Thermostat is a great choice because of the display and WiFi abilities. If you're having trouble with your furnace or just trying to get status, the Honeywell display can give you a tremendous amount of data easily.​
