Is Mysa Single- or Double-Pole?
Mysa is a single-pole thermostat but can be used to replace a double-pole thermostat in certain applications. If you are unsure, please contact a qualified electrician to confirm that your desired installation is within national building and electrical codes.
How many Mysas do I need?
Each Mysa is designed to work on its own — you can start with one thermostat and add more over time. To optimize your energy savings and comfort, we recommend starting with 3 thermostats in the rooms that matter most in your home.
More About Mysa
How does Mysa save me money?
Mysa Smart Thermostats are designed to help you reduce your monthly electricity costs by using home energy more efficiently (running your heaters as accurately and infrequently as possible).

The Mysa app’s smart features like Scheduling, Geofencing, and Eco-Mode help you optimize your comfort level while using less energy to heat your home.
How many heaters can I connect to Mysa?
Mysa is rated for controlling electric heating systems up to 3,800 watts. This allows you to connect multiple heaters to Mysa and allows for a number of customizations based on different-sized heaters.
Is my internet connection strong enough? Do I need a special router?
Each Mysa Thermostat uses a tiny amount of data — approximately 0.5 MB — per day. While Mysa does not require any special routers and is designed to work with most household routers, it does require a unique 2.4ghz connection.

Please ensure that your router is able to operate a 2.4ghz network, and is not currently set to a merged network.
How does Mysa use my data or location?
Mysa uses your data to enable energy-saving features such as Early On. Your location is required to enable Geofencing but is optional.

Respecting and protecting our customers’ data is our first priority.

Mysa will never share your personal data with other parties. We’ve passed CSA’s Cyber Security Audit for Data Storage and scored an A+ on their ‘Hacking Penetration’ testing, which means our cyber security is second-to-none. Please review our Technical Specification section for additional security information.
Is there a minimum and maximum temperature setting?
Mysa can be operated from 5℃/41℉ to 30℃/86℉. Mysa also has an Off Mode allowing the thermostat to completely turn off the heat.
Can I manually adjust the temperature on my Mysa thermostat?
Yes, you can control your preferred setpoint temperature from the thermostat’s faceplate. Adjusting the temperature manually will override your Schedule until the next set point change and will not interfere with any additional app settings!
Can I control multiple Mysas using my smartphone?
Yes, you can use the Mysa app on your smartphone to control up to 50 Mysa thermostat, and each Mysa account can include up to 10 homes — that means you can use the app to control up to 50 thermostats with just one account!
