Waking Up the CoreUpdated 9 days ago

The Core sensor is designed to save battery by moving between different power states depending on whether it’s in use, charging, or idle. Once you know what each state means, it’s easy to get your Core awake and ready to connect in the HELIOS App.

Quick Tips

  • Best practice: If you can’t get the Core to connect, try the double tap — this ensures it’s fully awake.
  • Look for LED glow: Any transition (from sleep or shutdown) is confirmed by the LED on the logo face.
  • On the charging pad: The Core is always awake, so it’s the easiest place to connect.

Notethe double tap motion replaces a previous shake-to-wake motion starting in our September 2025 firmware update.
