Can I use a single Mysa for multiple AC units in my home?

What modes and settings does Mysa support for air conditioning?
Currently, Mysa for AC supports Off / Cool / Heat, and Auto modes (where applicable)

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.
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.
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 to control up to 50 Mysa thermostats per device, 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!
What is Mysa’s 1-Year Energy Savings Guarantee?
We believe we’ve built a smart thermostat that will help you save by using home energy more efficiently.

If you are not satisfied with your energy savings after using your Mysa Smart Thermostat(s), you may return them for a full refund — risk-free satisfaction guaranteed. Learn more about Mysa’s 1-Year Energy Savings Guarantee.
How do I return my Mysa for a refund?
If you are within the 30-day Risk-Free Return window and you purchased your Mysa from this website, please review our Refund Policy for next steps.

If you purchased the product from an authorized reseller, you must request a refund directly from the reseller. Returns and requests for refunds to re-sellers are subject to the reseller's return/refund policy, which may differ from Mysa's store policy.
