Mysa Smart Thermostat Review

Smart thermostats are becoming increasingly popular because of their smart features that help save up on energy costs, connect to other smart devices, and the comfort that they provide in your homes.

Smart thermostats may seem like a huge investment but they are worth it because of their long-term cost-saving. It is important to be able to differentiate between smart, programmable, and wi-fi thermostats.

Smart thermostats often are also programmable and connected to the wifi, which makes them better than just the programmable and wifi ones. There are many different models out there that you can choose from which is why getting the perfect smart thermostat is not easy.

Smart thermostats can vary not in terms of the price, but also in terms of the systems that they are compatible with, and with the features they provide. While your budget should be the foremost determinant, the compatibility with other devices and HVAC systems should also be equally important.

If you are already a smart thermostat user then you should check out the ones that also feature advanced functions as they can provide greater comfort than the basic ones.

They also support voice assistants like Alexa, Siri, and Google Assistant, providing you with the ease to adjust your thermostat without even using your smartphone. That being said, you should be very careful with the smart thermostat you pick because the wiring and compatibility of your HVAC system need to be just right.

I also made the mistake of getting a smart thermostat that was not supported by my HVAC system. That is when I came across the Mysa smart thermostat.

This review will help you decide whether the Mysa Smart thermostat is made for your home or not.

Who should buysmart thermostats?

People who want to minimize their energy costs and use their HVAC system efficiently should invest in a smart thermostat. May smart thermostats save costs up to 23% annually, which is why a lot of people are shifting from their traditional thermostats.

Smart thermostats are also a good option if you already have a smart home ecosystem installed. Most smart thermostats support Amazon Echo, Google Home, and Apple HomeKit. However, many thermostats also cater to other lesser-known smart systems such as Samsung SmartThings, Nexia, IFTTT, and Cortana.

Generally speaking, a smart thermostat will benefit you if you go on trips a lot and the house is empty, but you still want control over your thermostats. Many smart thermostats come with smartphone apps that allow you to set schedules and adjust temperatures no matter where you are.

Moreover, if you have someone handicapped in the house, then investing in a smart thermostat will allow them to control the temperature by simple voice commands. Voice commands are also useful if your hands are occupied and you don’t have to get your phone or thermostat dirty.

If you are worried about the installation of a smart thermostat then you shouldn’t because most smart thermostats are a breeze to install with the help of the manual and videos available online. Thus, you will not have to worry about getting a professional to install it.

Factors to consider before buying Smart Thermostats:

Type of thermostat

Smart thermostats can vary in terms of their voltage and whether they are heat pumps, fan-based, ventilators, etc. Not all HVAC systems are compatible with all kinds of thermostats, thus you should ensure that the HVAC system is compatible with the one you are interested in.

Privacy/Lock features

A lot of people nowadays are increasingly becoming concerned about the availability of their data. When you integrate the thermostat with your system, all your patterns, schedules, etc inevitably also become available to the hackers on the internet or the companies that might use your data for their benefit.

Many people also look for child locks or security locks on their smart thermostats as they can be touchscreens and within the reach of children. Thus, if you want this feature in specific you should go for a smart thermostat that offers it, as all don’t.

Ease of installation

If you want a thermostat that you can install yourself then you should make sure other users have confirmed the ease of installation as some thermostats are more complicated than others.


This feature helps the thermostat know whether you are home or not. If it detects your phone’s GPS signals within the perimeter then it knows you are home. However, if it doesn’t then it adjusts the thermostat to a temperature that helps save up on your electricity bills.

Smart Sensors

Some smart thermostats come with different kinds of sensors such as proximity, humidity, etc, but the more simple and basic ones do not. Thus, if you think this is something you would be interested in, you should make sure the smart thermostat you are interested in has them.

Some, however, may not have sensors integrated into the thermostats but have the technology that supports the sensors and so the sensors can be bought separately as well.

Mysa Smart Thermostat and its Alternatives

The Mysa Smart Thermostat comes in two versions, one for baseboard heating systems and the other for in-floor heating systems. These options help you pick the one that is meant for your HVAC system.

The baseboard one is good for high or line voltage systems (including fan-based ones). What’s amazing about Mysa is the fact that it helps save energy costs by up to 26%.

Unlike other smart thermostats that only help save about 23%. The Mysa device is a very sleek and minimalist one, adding to any home’s aesthetic. Another thing that sets it apart is the large number of smart home systems that it is compatible with.

While the Mysa smart thermostat offers voice control and easy scheduling, it lacks one feature. We expect this feature from a smart thermostat i.e. geofencing. Many users look for this feature. It saves them the trouble of turning off the thermostat before leaving their homes.

Nest Learning thermostat

If you want this particular feature then the Nest Learning thermostat is a good alternative as it not only has smart sensor capabilities but also has advanced learning features that learn your thermostat patterns and make adjustments automatically.

While the Nest Learning thermostat is about $100 more expensive than the Mysa one. Still, it is great for someone who wants minimal involvement.

Ecobee 3 Lite

The Ecobee 3 Lite is also a suitable alternative to both the above-mentioned ones as it lies in the same price range as Mysa, has smart sensing capabilities, and is compatible with the same smart home systems as Mysa. The Ecobee 3 Lite also does not require a C-wire like the Mysa smart thermostat.

Honeywell Home T5

If you are looking for something cheaper Honeywell Home T5 is a cheaper alternative that has all the basic features wanted in a smart thermostat, in addition to its adaptive recovery features and smart alerts. However, it requires a c-wire connection.

All are equally good thermostats but the functions and compatibilities vary greatly. So at the end of the day it depends on your system’s requirements.


  • Compatible with Amazon Echo, Google Home Assistant, Apple HomeKit, IFTTT, and Samsung SmartThings
  • Built-in wifi adapter
  • Budget-friendly
  • Simple and easy to use the app
  • Saves up to 26% on energy costs
  • Stylish design


  • Minimalist design only displays the temperature
  • The wiring can be more complicated than the thermostat you are replacing
  • No geofencing feature


1. HVAC system compatibility

Mysa is one of the most popular and one of the few manufacturers of smart thermostats that are compatible with high-voltage heaters such as fan-forced convector, radiant ceiling, and baseboard ones.

Moreover, it does not need a c-wire to connect to the system and instead has a built-in wifi adapter. You can also check whether your HVAC system will be compatible with it online on their website.

2. Minimalist Design

This is one of the most sought-after features of the Mysa thermostat. It has a very sleek, dot-matrix display, which features touch-sensitive buttons. It gives off a very high-tech aesthetic to any house.

3. Smart Home Compatibility

This is also one of the many reasons why people like this thermostat. It is not only compatible with the three most famous smart home systems, but also supports IFTTT and Samsung SmartThings.

4. Zoning

Those who have line voltage heaters often have more than one thermostat around the house. Mysa helps make your life easier but the zoning option. This allows you to group the thermostats into zones. Doing so helps you to access multiple thermostats at the same time. This can also be made easier if you have IFTTT or Alexa.

What users think of the Mysa Smart Thermostat

Customer reviews are great to help you decide whether a product is for you. I too went through the many customer reviews left online about the Mysa smart thermostat.

Their website was particularly useful in this regard. A lot of customers had asked questions and they had been offered quick and swift replies and action. This shows their customer support is strong. According to many users, the installation is quite easy as the manual guide and online help were available.

People also appreciate its recent addition of the chart feature. It helps show usage statistics on a per day, week, or monthly basis and also comes with a cost estimator. The users also rave about how easy it is to use its app.

Final thoughts on the Mysa Smart Thermostat

The Mysa thermostat is a good fit for people who have high voltage systems and line voltage heaters. Particularly because there are quite limited options in the market.

The setup of the thermostat and the smartphone app is both reliable and easy. Moreover, the voice command makes it quite attractive for many, especially in the price that it comes for. It has a very attractive, minimal, and industrial design, which sets it apart from many other touchscreen thermostats.

Although Mysa constantly works on upgrading the thermostat’s capabilities, still it has a few shortcomings . For instance, its lack of geofencing support. However, since it does not work with low voltage systems, you will have to opt for alternatives.

A few of them have been mentioned in this review. You can pick one that suits your system’s capabilities in the best way possible.
