The installation of a Mysa must comply with the applicable Local and/or National Electrical codes and utility requirements. This installation should be entrusted to duly qualified personnel where required by law.

If you would like to install your Mysa yourself, we offer an online guide as well as in-app step by step instructions, to assist you.

Installing this product involves handling high voltage wiring. It’s important to follow installation instructions carefully. Turn off your circuit breakers and follow the proper safety precautions before proceeding.

If you are unsure about handling electrical wiring, please consult a qualified electrician.

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.

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.

Many utility companies offer rebates to help off-set the cost of purchasing energy efficient products like Mysa.

To find out if there’s a utility rebate offered in your area, check out our rebates page or contact your utility provider.

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.

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.
