Homeowners with high voltage (or line voltage) heating in North America have a few options when they look for a solution to lower their energy consumption and heating costs. Some of the more popular products on market include Mysa Smart Thermostats and the Wi-Fi thermostats from Sinopé and CaSA.

In this article, we will compare the Mysa Smart Thermostat with another high voltage thermostat, CaSA’s Caleo thermostat. We will focus on a side-by-side comparison of their compatibility, connectivity, control, integrations, smart features, and pricing.

Compatibility & Connectivity

While Mysa thermostats are compatible with both high voltage electric baseboard heaters and electric fan-forced heaters, CaSA warns that their Caleo thermostats are not compatible with fan-forced heaters. Regarding wattage and heating loads, the Mysa thermostats can take 3800W and Caleo can handle 3750W. We recommend that you verify the wattage connected to your current thermostat before you purchase a new thermostat. Here’s how.

When it comes to installation, CaSA can employ “in line” installation of two or four wires to a single pole like most high voltage thermostats, while Mysa requires four wires. The additional two wires for Mysa include one neutral wire (or Live wire for 240V applications) which powers both the thermostats and heaters and one ground wire.

Both Mysa and Caleo use embedded Wi-Fi connectivity, which allows them to connect to your home’s internet network. You do not need to purchase and install an additional hub to use either thermostat.

Controlling Thermostats

Mysa has a mobile app available for both Android and iOS devices which allows you to control thermostats individually and in heating zones. Because Mysa thermostats are joined to your home’s Wi-Fi network and connected with Mysa’s cloud service, you can control your thermostats on your mobile device from anywhere in the world.

CaSA does not have a mobile app, but it uses a web platform for programming Caleo thermostats. The web access allows users to control and monitor their heating remotely through any browser.

In regards to controlling thermostats manually, a Mysa thermostat has two touch buttons on the front which allow you to easily increase or decrease the setpoint for the room’s temperature. Caleo thermostats have a screen with virtual buttons that users can press to change the temperature.

Integrations

Mysa natively integrates with a wide range of smart home hubs and assistants, such as Amazon AlexaApple HomeKitGoogle Home, and IFTTT. Mysa Smart Thermostats are the only high voltage thermostats that integrate with Apple HomeKit. Additionally, there will be an integration available with Samsung’s SmartThings in early 2018.

CaSA’s Caleo thermostat integrates with IFTTT. You can view their IFTTT channel here.

Smart Features

Mysa Smart Thermostats will leverage its learning algorithms to learn about your preferences and schedules over time. The Mysa app will provide suggestions to improve your schedules and maximize energy savings. Mysa will also learn how long it takes for the room to heat up to the temperature of choice and will ensure the rooms in your home are comfortably warm exactly when you want them. For a detailed overview of the features of this smart thermostat, see this article.

The Caleo Wi-Fi thermostat by CaSA does not have any learning features, but it does provide reports on energy consumption and can be connected with IFTTT for extended home automation.

Pricing

Mysa thermostats are available starting at $125 per thermostat. The first Mysa shipments have been made in February and new orders will be sent in April.

CaSA sells its Caleo units at $129.99 CAD and requires a lead time of 12-15 days, according to their website. Caleo also offers a paid subscription service that has some advanced features including control lock-outs and multiple address management.
