How do I use the Leave or Arrive (beta) feature
This feature allows you to trigger some actions when you arrive at or leave a place. To use this feature, you must allow the app to always access your geographic location. Select Leave or Arrive (beta). Tap Leave and select a location. Tap Next and add conditions. You can then control your devices to execute preset tasks when you are within 110 m to 1,023 m of that location. If this function fails to execute correctly, please refer to "Why doesn't the Leave or Arrive (beta) feature take effect?".
