Operation

Transport Mode
They are shipped with batteries inside the sensor. Default the sensor is in transport mode which means not to activate operation.

Installation Mode

Users need to press the button over 5 seconds to activate operation into installation mode. When the Sensor tries to join the network, it will keep blinking for 3 seconds.
Once the sensor joins the network, the LED will keep on for 3 seconds and send an uplink.
Users can press the button for over 5 seconds to try to join the network again.
The device will send uplink three times with FW version when the device joined successfully.

Default Operation

During default operation the device will send a message to the network anytime there is a sufficient delta in the environmental conditions
- Water leakage status change dry/wet (dry to wet Buzzer alarm)
- Tamper detected (Buzzer alarm)
- Button pressed (No buzzer alarm)
- Keepalive message (No buzzer alarm).
Users can press the button to send a test message to the network.
The device will send a message saying it has been inactive for 60 minutes.
While in default mode the device will flash the LED 3 times within 100ms only when the user presses the test button.

Messages

LoRaWAN Packets for this device uses port 126.

Cautions
CAUTION: Disposal of a battery (or battery pack) into a fire or a hot oven, or mechanically crushing or cutting of a battery (or battery pack) can result in an EXPLOSION!
Leaving a battery (or battery pack) in an extremely high temperature surrounding environment can result in an EXPLOSION or leakage of flammable liquid or gas.
A battery (or battery pack) subjected to extremely low air pressure may also result in an EXPLOSION or leakage of flammable liquid or gas.
Discard used batteries according to the manufacturer’s instructions.
CAUTION: The unit is provided with a battery-powered circuit.
There is a danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
