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

Last updated: September 2, 2026

If Create Zone is missing, grayed out, or some thermostats never show in the picker, work through compatibility, Home, and owner vs shared login first.

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) will not appear as eligible. Those products can still share a Home, schedules, and shortcuts.

Same Home and online

  • Open Manage Mysa Homes and confirm every thermostat you want is assigned to the same Home. Zones are per 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 again from Zones > + / Create Zone. Give it a room name (for example Living Room). After save, selected thermostats sync to the same schedule and setpoint immediately.
