Removing and Resetting Your Thermostat

Last updated: October 27, 2026

This article tells you how to remove Mysa for Electric Baseboard Heaters from your account and how to reset it. It also tells you how to prepare Mysa for a new owner. Use the Mysa app on a phone or tablet.

Remove Mysa from your account

When you remove Mysa from your account, you cannot control it from the app. Mysa continues to control the heat. Mysa stays at its current temperature and no longer follows your schedule. Use the arrows on Mysa to change the temperature.

Only the primary homeowner can remove a Mysa.

  1. Open the Mysa app and select your Mysa.

  2. Tap the Settings tab.

  3. Tap Delete Device.

  4. Tap Confirm.

Then a different account can pair Mysa.

When to remove Mysa

  • You move out or sell your home: Remove each Mysa from your account before you give the keys to the new owner.

  • You give Mysa to a different person: Remove Mysa from your account so that the person can set it up.

Sharing access does not transfer the ownership of a used Mysa. See Sharing won't transfer a used thermostat.

Reset Mysa

V2, Lite and V1

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 you must 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. For more information, see Gen3: Pairing and reconnecting.

Pair Mysa again

  1. Download the Mysa app.

  2. Create an account or sign in.

  3. Tap + at the top right of the home screen, then Add a Mysa.

  4. Do the pairing steps.

Add new menu on the Mysa home screen showing Add a Mysa, Add a Schedule, Add a Zone, and Add a Home.

If you cannot get access to the first account

The app can show Can Not Pair This Mysa. This message tells you that the Mysa is on the account of a different user. Ask the previous owner to remove the Mysa from their account. Or send a photo of the serial number to support@getmysa.com. The serial number is behind the front plate. Refer to Ownership Transfer for a Used Thermostat.

Before you remove the front plate, turn off the circuit breaker. Make sure that the power is off.
