Sharing Won’t Transfer a Used Thermostat

Last updated: August 25, 2026

Sharing is for household members on a Home you already own. It does not move a thermostat off a previous owner’s account. Extra sharing invites will not take the device over.

When this happens

  • You bought a house with Mysa already installed

  • You bought a used thermostat

  • The previous tenant or owner still has the device on their Mysa account

What actually transfers ownership

  1. The previous owner removes the thermostat from their account (then you pair it to yours), or they delete the Home if they are leaving every device behind.

  2. If nobody can sign in to the old account, request an ownership transfer: unscrew the bottom screw, slide the faceplate off, photograph the serial number, and email it to support@getmysa.com.

  3. After support releases the device, pair it with the standard pairing steps — do not use Share Access for this.

Until the old account no longer holds the device, it will not appear during pairing and it will not show up as a shared thermostat on your login.
