Sense Range: Sensor LEDs

Sensors have 2 LEDs that indicate their status: Health LED and Mode LED. See images 1 & 2.

These LEDs do not appear on the sensors unless you press a Magnetic Tag (see image 3) on the bottom left corner of the sensor for 3 seconds.

Caution: The Magnetic Tag may interfere with pacemakers and implantable cardioverter-defibrillators (ICDs). Keep the tag at a safe distance from such devices

See the images below to locate the LEDs and tag press position on Cold/Hot Sensors and Sensor+.

See the tables below to interpret the LEDs.

	Mode LED
Flashing green → flashing amber	Magnetic Tag detected. Remove the Magnetic Tag and see the Health LED for more information about the sensor’s status.
Flashing green → flashing amber → solid red	Device decommissioned Please contact us.
No LED	If the Mode LED does not illuminate after you press the Magnetic Tag: The battery may be dead (in which case, you would have previously received a low battery alert) The device may have been damaged If it is a: Cold Sensor or Hot Sensor, replace the sensor Sensor+, replace the battery then tag the device again with a Magnetic Tag. If you still see no LEDs, contact us for a replacement.

Mode LED

Flashing green → flashing amber

Magnetic Tag detected.

Remove the Magnetic Tag and see the Health LED for more information about the sensor’s status.

Flashing green → flashing amber → solid red

Device decommissioned

Please contact us.

No LED

If the Mode LED does not illuminate after you press the Magnetic Tag:

The battery may be dead (in which case, you would have previously received a low battery alert)
The device may have been damaged

If it is a:

Cold Sensor or Hot Sensor, replace the sensor
Sensor+, replace the battery then tag the device again with a Magnetic Tag. If you still see no LEDs, contact us for a replacement.

	Health LED
Green	Good signal strength
Amber	Moderate signal strength
Amber flashing	The sensor is not registered on your account. See Install a Sensor.
Red	Poor signal Remove items that may be blocking signal to the hub. If a sensor, hub, or repeater has been moved, return it to its original location.
1/2 red flashes	Low/critically low battery If it is a: Cold Sensor or Hot Sensor, replace the sensor Sensor+, replace the battery
No LED	If the Mode LED does not illuminate after you press the Magnetic Tag: The battery may be dead (in which case, you would have previously received a low battery alert) The device may have been damaged If it is a: Cold Sensor or Hot Sensor, replace the sensor Sensor+, replace the battery then tag the device again with a Magnetic Tag. If you still see no LEDs, contact us for a replacement.
