Pairing

Resetting the Device/Restore to Factory Defaults

  1. Remove the battery to power off the device.
  2. Press and hold the only button.
  3. Re-install the batteries to power on the device

If the device is asleep (which is most of the time) and you need it to be awake for some reason, tap the only button on the device. The LED will flash 5 times and the device will be awake for a brief period.

Status of Functions

  1. Temperature monitoring - Works
  2. Humidity monitoring - Works
  3. Battery monitoring - untested.
    • In theory the device LED will flash ONCE if the voltage falls below 2.4V
    • In theory the device will send a low-power report to the ZigBee network if the voltage falls below 2.4V - no other battery reporting.
