3. Operation
3.1 Transport Mode
Sensors are shipped with a plastic battery insulating pull tab that must be removed
before the operation.
3.2 Default Operation
While in default operation, the device will send a join request message after booting for a
minute. After joining successfully, the device will detect water leakage every 5 minutes.
Once the sensor detects water leakage, it will send a status message immediately.
4. Messages
