For so long until 2017, a proper smart thermostat was not available for baseboard heaters and line voltage based heating systems. In 2017, MySa thermostat was launched in the market – which is a smart thermostat exclusively designed for line voltage heating systems like baseboard heaters, fan forced heaters, convectors and for radiant ceiling heaters. MySa comes packed with a lot of smart features like WiFi connectivity, internet based control using apps, voice control by interfacing to smart home hubs (Alexa, Homekit, Google Home etc), energy reports and a lot more.
Thermostats were really “old school” till 2011, and many households were using a simple digital programmable or manual thermostat variant. A revolution was started when Nest labs first introduced smart thermostats in 2011. Since then, lots of new smart and internet connected models like Ecobee, Honeywell RTH9585WF, and Emerson Sensi has gained popularity.
All these revolutions were happening in low voltage thermostat models suitable for central furnaces, heat pumps and central boiler systems. No innovation was happening in thermostats for line volt systems like baseboard heaters until 2017, and Empowered Homes Ltd (headquartered in Canada) put an end to this by launching its innovative smart thermostat Mysa for line volt systems.
In a nutshell, Mysa is currently the best WiFi enabled smart thermostat for line voltage systems, which can be controlled via internet, has a user friendly mobile app, can be interfaced to smart home hubs for voice control, and is compatible with 120/240 volts, delivering a max output power of 3800 watts at 16 amps current.
This beautifully designed 5.7” tall x 3.8” wide x 1.1” thick thermostat comes in soft white rectangular box type structure. This sleek design blends well into any wallpaper and gives a stylish, elegant look to your wall.
The subtle LED light on its surface shows the ambient room temperature and two control UP/DOWN arrows. The controller is cooled by the heat sink that adds to the big size of this thermostat.
This unit is compatible with the 120V/240V line heating systems like the electric baseboards and supports loads up to 3800Watts.
In order to control the device remotely, you will need to first install the device and then set up the app on your phone. The app works in both android and iOS devices, and allows you to set up customized comfort from literally anywhere.
The device has self learning abilities and learns your schedule, that is if you have a fixed routine, and programs accordingly for you.
There are quite a few smart, self learning line voltage from Stelpro, ATMOS etc. Here, we shall talk about the features those MYSA smart thermostat posses.
What makes MySa smart thermostat different?
One of the major problems that some of the smart thermostats faced was the lack of proper connectivity and the need for a third party hub. MYSA thermostat has been designed to overcome these issues.
It has relatively good wi-fi connectivity and the MYSA app is also quite user friendly. You need not be a tech guru, to use this app.
Also it works with the popular smart home hubs like Amazon Alexa, Apple HomeKit, IFTTT etc. This means you need not require to install any third party hubs.
Therefore, if all you want in a smart thermostat is that it should work well with its wi-fi connections, MYSA thermostat is the right choice for you.
The Mysa thermostat sports a sleek, modern, yet minimalist rectangular design. It looks like a small white box which may seem a bit thick. It adds to the style quotient of your modern home.
The display shows current room temperature and two arrows (up/down) to change the temperature setting on device. Temperature and the arrows are displayed using LED, which resembles the dotted displays of the past with a modern outlook. The display is capacitive touchscreen, and the UP/DOWN arrows can be touched to increase or decrease the temperature setting.
Mysa is a little bulkier in build and the thickness is due to the big heat sink used to cool off the Triac based switching IC. Many conventional thermostats uses relay based switching which is inefficient compared to triac switching. Though the use of triac makes the device bulkier, it gives significant benefits in terms of faster switching, higher efficiency and energy savings.
The brightness of the display can be adjusted through the mysa app. It can be turned completely off or set to a light in the 10- 100 percent brightness range. It is wired directly to the power supply and hence discards the need of using batteries.
Next thing, which makes a thermostat smart, is its in built sensors. Let us see what this thermostat has to offer in regard to its sensors.
If we talk about its in-built sensors, then it is embedded with humidity and temperature sensors. These predict the amount of humidity and temperature of your room. It reflects the measured value on its screen, through a subtle LED light. This helps the thermostat to maintain the temperature of the room.
When the temperature sensor measures the room temperature to a value, which is far from the set value, the thermostat works at a high power. This power is reduced as the room temperature approaches the set value.
The display shows how much power is being used by the thermostat. A single small flame indicates low energy consumption, while 3 small flames indicate highest energy consumption.
The one drawback with this model is that it lacks motion sensor. This effectively means that it does not offer any native geo fencing feature, which is one of the helpful tools in reducing the energy usage.
Talking about the remote sensors, it senses the outside temperature when integrated with the smart hub like IFTTT through the MYSA app on your phone.
Temperature Precision: +/- 0.4 F / 0.1 ℃
Humidity: +/- 2%
Control Range: Complete Off, 5-30 ℃
MYSA can be controlled from anywhere through its app on any android/iOS device. You can set the temperature and schedule according to your routine, easily through this app. You can set up to a total of 56 temperature set points for the whole week. This means that, if you spread the temperature set points evenly over the week, you can set up to 8 temperature values a day.
You can create zones in your home, by using two or more thermostat which needs to work on same schedule, through the MYSA app. You can create your customized schedule and save it for future. Also, if you have a fixed routine, the MYSA thermostat learns it and implements it accordingly. Your thermostat will work according to your schedule, and deliver its best performance. In case you need to change the temperature in a particular zone, you can use the “Hold indefinitely” option. This overrides the set temperature to the new value.
When you invest in such a high priced smart thermostat, you need to know if its worth the price. A smart thermostat is placed in your smart home, to help you save energy in a smart way. So, you have to choose a thermostat which would help you for the same.
How this smart thermostat aids in saving the energy? Well. it generates real time energy usage reports which lets you check where and how much energy is being wasted. This helps you in generating an optimal schedule that not only suits your life style, but also your pocket.
Another cool feature is its easy to activate, vacation mode. If you are going away on a vacation, then set the vacation mode on. The thermostat will work accordingly.
There is also an option to cut off the supply between the thermostat and the heater. This means, you can use the thermostat only when it is needed.
The MYSA app also estimates how much energy bill you will have to pay, according to the energy usage.

- Lack of motion sensor.
- No native Geofencing, which is quite useful in reducing the energy consumption.
- Does not support Samsung smartthings hub as of now.
- Use of large heat sink for the TRAIC IC makes the product thick and bulky.
To wrap up, MySa is currently the best line voltage thermostat with WiFi feature for systems like baseboard heaters. If you’re serious about WiFi feature, you should not look beyond MySa as its wireless connectivity is very reliable. Also, there are not many choices for line volt thermostats with WiFi feature and a well designed mobile application. Though there are models like Stelpro KI, they require third party hubs like an Z wave controller to connect to home WiFi network or internet. And the mobile app for Stelpro model is substandard. Overall, MySa is really a winner & the best choice (if you’ve enough budget) as a modern, smart line voltage thermostat.
