• Simple, wall-mounted touchscreen with intuitive menus.
• Includes a C-wire adapter for easy installation on most systems.

The strength for Honeywell is dependable, customizable comfort. The brand isn’t trying to reinvent the wheel or do anything revolutionary. 

So, where does that leave you in choosing between Nest vs Honeywell vs Mysa?

Nest Thermostat vs Honeywell Thermostat vs Mysa Thermostat

We’re comparing three very different solutions in looking at Honeywell vs Nest vs Mysa thermostats. Two of these (Nest and Honeywell) are primarily made for low-voltage HVAC systems. Mysa works across a much more broad range of heating and cooling solutions. 

That’s not the only difference between the Nest thermostat vs Honeywell thermostat vs Mysa thermostat, either. Let’s take a closer look at the most important nuances below so you can make the most informed decision.

System Compatibility and Target Users

Low-voltage (24V) HVAC systems are common in homes with central forced-air systems, and Nest and Honeywell are made with these types of systems in mind.

The Nest works with furnaces, heat pumps (with or without auxiliary heat), and central A/C systems. Honeywell supports multi-stage heating and cooling systems and adds optional room sensors to expand coverage.

Meanwhile, Mysa is designed for high-voltage electric heating and cooling systems. That includes electric baseboards, convectors, in-wall fan-forced heaters, in-ceiling radiant systems, and even mini-split heat pumps or AC units via its IR-based controller.

This is why Mysa is the obvious choice over Honeywell or Nest if your home relies on electric heating rather than gas or oil, which is becoming more and more common in Canada and the Northern US.

Smart Features and Automation Style

It’s hard to beat the Nest thermostat in terms of automation. Its learning algorithm automatically builds heating and cooling schedules based on usage patterns. It also leverages motion and proximity sensors to switch between “Home” and “Away” modes and integrates with Google Home for full ecosystem automation.

On the other hand, Honeywell’s T9 forces you to manually customize your heating and cooling schedules. That’s not a bad thing if you want to be in complete control of things, though. This thermostat does have a geofencing feature that automatically adjusts settings when you leave or return. 

Mysa’s smart features take a more practical, data-driven approach. Instead of relying on predictive learning, it empowers you to build your own custom schedule while still offering automation through geolocation, energy insights, and smart home integrations.

Another really cool feature of the Mysa thermostat ecosystem is zone grouping. This lets you control multiple devices simultaneously, which neither Nest nor Honeywell handles natively. 

Ease of Installation and Setup Experience

All three brands in this comparison are relatively straightforward to install. 

The Nest thermostat takes around 30 minutes with guided setup via the Google Home app. It doesn’t require any sort of C-wire thanks to its Power Sharing feature, though certain systems still benefit from one.

In contrast, Honeywell’s T9 does need a C-wire or the included power adapter. Its step-by-step app walkthrough is still pretty intuitive, and setting up the additional room sensors is simple once the main thermostat is online.

Mysa takes a different approach since it’s designed mainly for line-voltage wiring (120V or 240V). It connects directly to electric heating circuits. While this means you need to turn off the breaker and connect a few wires, it’s still really user-friendly thanks to the in-app visual guides and color-coded terminals.

App Experience and Voice Assistant Ecosystem

Nest integrates tightly with Google Home for a seamless experience with energy usage charts, remote temperature control, and adaptive Eco Mode settings. The app is clean, but it is locked into the Google ecosystem - sorry, Apple users!

Honeywell Home’s app is easy enough to use, too. You get intuitive control over scheduling, temperature zoning, and geofencing. It supports both iOS and Android, integrates with Alexa, Google Assistant, and SmartThings, and you can even set up push notifications for system issues or filter changes. 

Mysa’s app is arguably the most intuitive for managing multiple devices or zones, though. You can set custom schedules, access live energy data, and monitor total usage across rooms. The app supports Apple HomeKit, Alexa, Google Assistant, and SmartThings, and newer Mysa models support Matter!

Accuracy, Comfort, and Energy Savings

You’d be surprised to learn just how much you can save by upgrading to a smart thermostat. For instance, Nest can save you 12% on heating and 15% on cooling through its learning algorithms and Eco Mode automation.

Mysa takes things even further, though. It offers energy savings of up to 26% for electric systems, thanks to direct system control (no IR lag), precise thermostat calibration, and easy access to energy usage analytics.

It’s worth noting that Honeywell’s T9 might save you money on your monthly energy bill, but it’s hard to say how much since the company doesn’t explicitly make any claims about efficiency.  

Long-Term Value and Warranty Comparison

Now, let’s get to the cost comparison between Nest vs Honeywell vs Mysa. It’s important to keep in mind that price alone doesn’t always paint the full picture - but in this case, the most affordable option is the best one! 

• Nest: $229-$279, backed by a 2-year limited warranty
• Honeywell T9: $179-$249 with a 2-year warranty.
• Mysa: $139-$199 with a 2-year warranty 

What sets Mysa apart, aside from the obvious differences in dollars and cents, is longevity and relevance. We’re seeing more and more homes transition to electric systems, and Mysa is future-ready with Matter integration and energy data transparency.

Don’t get us wrong, Nest and Honeywell offer premium finishes and bring their own unique benefits to your home. But you can’t beat the precision, platform flexibility, and compatibility that Mysa offers - this is what truly future-proofs a home!
