5. Restore to Factory Setting
Operation method: press and hold the button for 5 seconds and the green LED flashes for 20 times,
and the device will be turned off after the operation.
6. Sleeping Mode
The device is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is one hour. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → the device will enter sleeping mode and wake up every 15
seconds to search a network to join in the first two minutes. After two minutes, it will wake up
every 15 minutes to request to join the network.
If it's at (B) status, to prevent this unwanted power consumption, we recommend that users
remove the batteries to power off the device.
7. Low Voltage Alarming
The operating voltage threshold is 3.2V. If the voltage is lower than 3.2V, the device will send a
low-power report to the Lora network.
8. Installation
This product comes with a waterproof function. When using it, you can attach the back side to the
iron surface, or use screws to fix both ends to the wall.
Note: To install the battery, use a tool such as a screwdriver to open the battery cover.
