Pairing Your Mysa for Electric Baseboard Heaters

Last updated: October 27, 2026

This article tells you how to connect Mysa for Electric Baseboard Heaters to the Mysa app.

Before you start

  • Mysa app: Install the latest version of the Mysa app from the App Store or Google Play. The app needs iOS 15.1 or later, or Android 8.0 or later.

  • Primary homeowner: Only the primary homeowner can add a Mysa. Shared users cannot add a Mysa.

  • Installed and powered on: Mysa must be installed and powered on. Mysa must show a pairing icon. For installation, refer to Installation Overview.

  • Bluetooth: Turn on Bluetooth on your phone. Your phone must have Bluetooth 4.0 or later.

  • 2.4 GHz Wi-Fi: Mysa connects to 2.4 GHz Wi-Fi only. Mysa does not connect to 5 GHz Wi-Fi. Have your network name and password ready.

  • Wi-Fi password: Wi-Fi passwords are case-sensitive. Make sure that there are no extra spaces.

Pairing icons

  • Gen3, V2 and Lite: Bluetooth symbol

  • V1: Wi-Fi symbol

If you do not see a pairing icon, Mysa is possibly paired already. Or you must put Mysa in pairing mode:

  • V2, Lite and V1: Reset Mysa. Hold the up arrow and the down arrow for 10 seconds, until the Mysa smile shows. Mysa removes its Wi-Fi, its Apple Home (HomeKit) pairing, its schedule and its settings. Mysa restarts and a pairing icon shows. Then set up Mysa again in the Mysa app.

  • Gen3: Hold the up arrow and the down arrow until the countdown on the screen ends. Gen3 resets its Wi-Fi and removes all its smart home (Matter) connections. Then set up Gen3 again in the Mysa app, and add it to your smart home app again.

Pairing steps (Gen3, V2 and Lite)

Gen3, V2 and Lite pair over Bluetooth. Gen3 starts in Bluetooth pairing mode when you first turn on the power.

  1. Open the Mysa app. Sign in, or create an account.

  2. On the home screen, tap +. Then tap Add a Mysa.

  3. The app asks: "Is the Mysa installed and powered ON?" Tap Yes, ready to set up.

  4. Choose your home.

  5. Tap All other Mysa.

  6. The app asks which icon you see on your Mysa. Tap Bluetooth Symbol.

  7. When the app asks for Bluetooth access, allow it.

  8. Stand in front of your Mysa and tap Next.

  9. Select your Mysa from the list. Tap Identify. Your Mysa smiles. Tap Yes.

  10. Accept the Bluetooth pairing request on your phone. Do this quickly, because the request stops after a short time.

  11. Name your Mysa.

  12. Select your 2.4 GHz network. Enter the password.

  13. Select your heater type. Refer to "Heater types" in this article.

Note: Your router can use one network name for the 2.4 GHz band and the 5 GHz band. If Mysa cannot connect, split the two bands for a short time. Or set up a 2.4 GHz network.
