First-Time Setup Checklist

Congratulations on your new Mysa smart thermostat! Follow this checklist to get your thermostat installed, connected, and optimized.

Before Installation

  • Verify your heating system is compatible with your Mysa model

  • Download the Mysa app from the App Store (iOS) or Google Play Store (Android)

  • Create your Mysa app account

  • Confirm your WiFi network is 2.4 GHz (5 GHz is not supported)

  • Have a screwdriver ready for installation

  • Locate the circuit breaker that controls your heating zone

Important: Always turn off the circuit breaker for the heating zone before starting installation. Never work with live electrical wires.

Installation

  1. Turn off the circuit breaker for the heating zone

  2. Remove your existing thermostat from the wall

  3. Take a photo of the existing wiring before disconnecting anything

  4. Identify your wires (line, load, and ground)

  5. Connect the wires to the Mysa backplate following the included wiring guide

  6. Mount the backplate to the electrical box

  7. Attach the Mysa thermostat to the backplate

  8. Turn the circuit breaker back on

Warning: If you are not comfortable working with electrical wiring, hire a licensed electrician to install your thermostat. Improper installation can cause damage and will void your warranty.

Tip: The Mysa app includes an interactive installation guide with step-by-step instructions and diagrams for your specific model.

App Setup and Pairing

  1. Open the Mysa app on your phone

  2. Ensure Bluetooth is enabled on your phone

  3. Tap the "+" button to add a new thermostat

  4. Follow the on-screen instructions to pair via Bluetooth

  5. Connect the thermostat to your 2.4 GHz WiFi network

  6. Name the thermostat and assign it to a room/zone

Tip: Keep your phone within a few feet of the thermostat during Bluetooth pairing. If pairing fails, toggle Bluetooth off and on, then try again.

Configure Your Settings

Once your thermostat is connected:

  • Set your preferred temperature units (Celsius or Fahrenheit)

  • Create a weekly heating schedule based on your routine

  • Set your local electricity rate for energy monitoring (found on your utility bill)

  • Enable Early On if you want the thermostat to pre-heat your space on schedule

  • Explore zone grouping if you have multiple Mysa thermostats

Connect Smart Home Integrations (Optional)

If you want voice control or home automation:

  • Apple HomeKit: Open the Apple Home app and scan the HomeKit code on your Mysa

  • Google Home: Search for the Mysa integration in the Google Home app

  • Amazon Alexa: Enable the Mysa skill in the Alexa app

Note: Smart home integration setup is done after initial app pairing. See our Smart Home Integrations Overview article for detailed instructions.

Verify Everything Is Working

  • Confirm the thermostat displays the current room temperature

  • Test that you can adjust the temperature from both the thermostat and the app

  • Verify your heating system turns on when the set temperature is raised above room temperature

  • Check that your schedule is set and active

  • Confirm WiFi connection is stable (shown in the Mysa app)
