My thermostat does not appear in Apple Home even though it shows as connected. What should I do?

If your thermostat (models TH1123WF, TH1124WF, TH1310WF, TH1400WF) shows as connected to Apple Home but does not appear in the HomeKit app, first check its location in the app. I If it is missing, perform a factory reset by following the procedure described to clear the pairing data, then restart the setup with Apple Home.

In some cases beyond our control, the thermostat may display a connection status to Apple Home even if it does not appear in the HomeKit app.

Here is the procedure to resolve this issue:

1. Check the thermostat’s location in HomeKit

  • Make sure the thermostat has not accidentally been placed in another of your locations (homes, rooms, etc.) during the initial setup in Apple’s Home app.

2. Perform a factory reset

  • If the thermostat does not appear in any of your HomeKit locations, a factory reset is necessary to clear the incorrect pairing data.

Factory reset procedure:

  1. Hold the top button down for 10 seconds after reaching the maximum setpoint to access the “Information” page.
  2. Once the thermostat switches to a new screen, press and hold both buttons simultaneously until “CLR” appears on the screen.
  3. Press one of the buttons until “Yes” appears on the screen.
  4. Press both buttons simultaneously to confirm.

Your thermostat will restart after this procedure. You can then restart the setup and pairing process with Apple Home.
