I’ve been looking for a sleek line voltage thermostat to replace my current one for quite some time. I later discovered that most of the businesses that dominate the smart home market only sell smart thermostats for low voltage devices, which was disappointing.
To use baseboard, ceiling, and forced fan heaters, I required a smart line voltage thermostat that could work with all of them.
However, obtaining such a high-quality line voltage thermostat was not easy. This item is required to be compatible with my existing heating system.
Compared to a regular thermostat, it must include smart features that make it worthwhile to purchase.
So, after several hours of investigation, I’ve come up with a solution for you. Every major line voltage thermostat on the market has been analyzed and contrasted, and the results are presented here for your consideration. I wrote this article to help others who are in a similar situation.
I’ve also included a thorough Buyer’s Guide to assist you in making an informed decision about which thermostat is the best fit for your needs.
Before finalizing my decisions, I considered the ease of installation, the ease of use, the energy efficiency, and the availability of technical support.
If you’re in a hurry, the Mysa Smart Thermostat is a smart choice because of its high voltage compatibility, good control, and connectivity with Google Home, Apple HomeKit, Alexa, and IFTTT, among other services.
Most electric space heaters employ line voltage thermostats, the most common type of thermostat used. Some programmable thermostats have the capability of controlling line-voltage equipment. It is crucial to understand this since installing a low voltage thermostat on a line voltage circuit can result in the thermostat failing or even causing a fire to break out. With programable thermostats, you can make things a little easier on yourself by programming them to only heat your home while you are there in it. Some of them may be programmed to turn on the heating immediately before you arrive home, ensuring that you always return home to a comfortable and warm setting.
In this review, you will learn about five different line voltage thermostats currently available on the marketplace. Some of them are programmable, while others are not; you may choose which one would be the most appropriate for you and which one would best meet your requirements and requirements.
Line voltage thermostats are available in both programmable and nonprogrammable configurations. Consider purchasing a nonprogrammable thermostat if all you need is a simple thermostat to control the temperature in your home, and most importantly if you spend a lot of time at home. As an alternative, if you have a hectic lifestyle and are not at home for the majority of the day, and you want to save money while also using a little less energy, you should consider purchasing a programmable thermostat to reduce your energy use.

It is extremely simple to set up, and I could get it up and running in less than 20 minutes after I purchased it.
Mysa has rich online documentation and video tutorials that explain how to set it up yourself.
However, if you have no prior knowledge in this field, I recommend hiring a professional electrician to complete this task.
It is compatible with high voltages and can be controlled with simple-to-use software, accessible for both iOS and Android devices.
The thermostat may be controlled and monitored remotely once connected to the app via Wi-Fi.
One of the most significant features of this thermostat is its smart integration. You can make it compatible with smart homes by integrating it with Google Home, Alexa, and Apple Homekit, among other services.
This enables you to use your voice to control your thermostat. It can also be used in conjunction with IFTTT, which allows you to design bespoke replies and perform various actions. IFTTT simplifies the process of creating schedules, monitoring and controlling the temperature, and viewing the current state of your heater.
Mysa has also made its thermostat highly energy-efficient, a great addition. Using a smart thermostat instead of a traditional thermostat can save up to 26 percent on your energy expenditures.
And who doesn’t appreciate the idea of getting more features for less money? There is a pretty attractive graphic in their app that shows your energy consumption and informs you of how much energy you have conserved so far.
I found this information to be quite beneficial, especially because it was visually appealing rather than through cold, hard figures.
When you are away from home, you can use their vacation mode to turn off all of your devices’ functions.
This has the potential to significantly lower your electricity bills. Using the app, you can create unique schedules for your devices and assign them your desired settings in a few simple steps.
The instruction manual has a thorough discussion of all of the required specifics. If you are stuck on something, their Tech Support will be happy to assist you.
It also has geofencing capabilities. This implies that you can program your heater to turn on or off when you regularly enter or exit a room.
It also makes use of geolocation, which calculates whether or not you are at home and, as a result, controls the heating in your room to reduce redundancy while heating up the room.
If you experience a power outage, the Mysa thermostat’s only negative is that you will have to manually reconnect it afterward.
Nonetheless, you receive many useful features, like good heating cycles and smart home connections, among others.
All of this is available at a reasonable price, which is why the Mysa smart thermostat is the best line voltage thermostat available today.
