Why won't my thermostat connect to Apple® HomeKit™?

Use the following steps to connect your thermostat to Apple HomeKit:

  1. Check the model number of your thermostat to make sure it is HomeKit-enabled.
  2. Check the wiring of your thermostat. If the thermostat does not have a C-wire, please contact your installer. Make sure your Lyric app is has been updated to the latest version.
  3. Make sure your smartphone is connected to Wi-Fi or is using your smartphone's data. If Apple HomeKit is still not working with your Lyric T5 Wi-Fi thermostat, call our customer support at 1-800-633-3991.
