Wake a Hailie® Sensor for the first time.

If your Hailie® sensor has a Battery Saver Pull Tab, simply remove it to wake the sensor. The LED will flash green once the Hailie® sensor and will automatically enter pairing mode (flashing blue LED) that lasts for up to 60 seconds.

If your Hailie® Sensor doesn’t have a Battery Saver Pull Tab, follow these instructions to wake up your sensor:


To wake the Hailie® Sensor, hold down the Status Button for 3 seconds and then release.

Press the Status Button once more to check the battery level. The sensor LED should flash green prior to the first use.


Before first use, place the Hailie® Sensor on charge for a minimum of 3 hours or until the LED / Battery LED (depending on the sensor type) stops flashing.  The Hailie® Sensor is now ready to use.
