6 Best HomeKit Thermostat Models For 2022

We scoured the market and ultimately determined that the best Apple HomeKit Thermostat is the EcoBee Smart Thermostat with Voice Control. We chose this particular smart thermostat as our Editor's Choice because we think it offers the best mix of design, features, and functionality at a price-point that remains competitive in the market.

The runner-up pick for a new thermostat with HomeKit compatibility is Honeywell's T9 Smart Thermostat. This higher-end thermostat from Honeywell offers high compatibility, an easy setup, and advanced features like auto home/away mode and multi-room focus via an optional add-on room sensor.

The best affordable HomeKit thermostat is the iDevices Smart Thermostat. Priced under $100, this smart programmable thermostat offers competitive features including voice control, remote access, and HomeKit compatibility without the need for an additional hub, but isn't the most appealing design to look at.

Are Nest thermostats HomeKit compatible? Why Are They Not on the List?

What Are Some Benefits of HomeKit Thermostats?

Offering HomeKit compatibility is one of the most requested features for anyone looking to build a modern smart home system and it often comes with the best thermostat models. Here are some of the differentiating features and added benefits from HomeKit

1. HomeKit thermostats are more efficient than traditional thermostats, which can save you money on your energy bills

Since HomeKit enabled thermostats are connected to Apple's HomeKit ecosystem, the app works more like a command center rather than an app on your phone. This means HomeKit-enabled thermostats can provide you with notifications when the temperature changes without you needing to open the app.

HomeKit thermostats can also help you understand how much energy savings you gain (which equates to more money in your pocket) compared to a traditional programmable thermostat by breaking the data down further.

2. HomeKit thermostats can be controlled remotely with your smartphone or tablet, so you can adjust the temperature even when you're not home

Since Apple HomeKit thermostats are technically smart thermostats, they have specific connective features that let you control them from anywhere. These thermostats also work with other HomeKit products you have in your smart home system, so you can conveniently control multiple HomeKit devices at once to make sure your home is comfortable.

3. HomeKit thermostats are compatible with a wide range of smart home devices, which means you can control your entire home's climate with just one app & communicate between devices

The interconnectivity of Apple HomeKit thermostats and HomeKit accessories you attach to your HomeKit system gives it the ability to communicate between HomeKit devices so they can work in tandem. For example, you can program your Apple HomeKit compatible thermostat to not continue to heat or cool your home if one of your window or door sensors is in an open state, thus saving on energy efficiency.

4. Some HomeKit thermostats come with built-in sensors that can detect whether someone is home or not, and adjust the temperature accordingly

While some non-HomeKit thermostats like the Nest Learning Thermostat do this, many of the best HomeKit thermostats will track your location via your Apple device and tell your HVAC systems to pause, resume or adjust their normal operation to help you save energy on your heating and cooling bills.

5. Many HomeKit thermostats have voice control capabilities, so you can adjust the temperature without ever having to fumble with any dials or mobile apps

If you have an iPhone or iPad, you can use Siri to control your HomeKit devices by just using your voice. This is a convenient feature, especially if your hands are full or if you just want to adjust the temperature quickly, on the fly.


Ending Summary

In the end, there are a lot of Apple HomeKit friendly smart thermostats on the market, and determining which one to buy to replace an old thermostat is not always an easy task. However, taking the time to do your research (hopefully with our help) can allow you to make a wise investment that will pay for itself many times over time thanks to the increase in energy efficiency.

While all of the best HomeKit thermostats listed within this guide will be suitable for satisfactory usage, we think the best model overall is the EcoBee SmartThermostat with Voice Control which offers the ideal overall package in terms of design, features, and functionality for most consumers that are looking to purchase a new thermostat with built-in HomeKit compatibility.
