Can’t Create a Zone or Thermostats Don’t Appear

Last updated: August 20, 2026

If Create Zone is missing, grayed out, or some thermostats never show in the picker, work through the checks below.

Compatibility

Only Mysa for Baseboards V1 and V2 can be added to a zone. Lite, in-floor, mini-split, and Mysa Smart Thermostat (central HVAC) devices will not appear as eligible.

Same Home and Online

  • Open Manage Mysa Homes and confirm every thermostat you want is assigned to the same Home

  • If a thermostat is offline or still pairing, finish Wi-Fi setup first

  • A thermostat already in another zone will not be available until you delete that zone

Shared Users

Only the home owner / primary user can create and delete zones. If you were invited as a shared user, ask the owner to create the zone.

App Refresh

  1. Force-close and reopen the Mysa app

  2. Confirm the app is up to date

  3. Try creating the zone again from Zones > + / Create Zone
