1. Introduction

R718WB is a LoRaWAN device compatible with LoRaWAN protocol (ClassA). When the R718WB sensor detects a leak, it will send an alarm

message to the gateway. When the sensor detects no leaks, it will send a message that shows no leak to the gateway.

LoRa Wireless Technology:

LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods,

LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless

communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main

features include small size, low power consumption, transmission distance, anti-interference ability and so on.

LoRaWAN:

LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different

manufacturers.

Sleeping Mode

The device is on and in the

network

Sleeping period: Min Interval.

When the reportchange exceeds setting value or the state changes: send a data report according to Min Interval.

The device is on but not in

the network

First two mins: wake up every 15 seconds to send request.

After two mins: enter sleeping mode and wake up every 15 minutes to send request.

Note: Suggest to remove batteries if the device is not used.

Suggest to check the device verification information on the gateway or

consult your platform server provider.

Low Voltage Warning

5. Data Report

When the device is turned on, it will immediately send a version package and a data report of water leakages/voltage.

Data will be reported once per hour by default setting.

(If there is special customized inquiry, the setting is changed according to customer requirements.)

Maximum time: 3600s

Minimum time: 3600s

Default reportchange:

Battery ---- 0x01 (0.1V)

R718WB sensor is triggered:

When the R718WB status changes, it will send warning report.

No water leak:0

Water leak:1

The reported data is decoded by the Netvox LoRaWANApplication Command document and http://www.netvox.com.cn:8888/page/index

Data report configuration and sending period are as following:

(1) Configure device parameters MinTime = 1min, MaxTime = 1min, BatteryChange = 0.1v

Downlink: 0112003C003C0100000000

The device returns:

8112000000000000000000 (configuration is successful)

8112010000000000000000 (configuration failed)

(2) Read device parameters

Notes :

1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.

2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval. If the data

variation is not greater than the last data reported, the device reports according to MaxTime interval.

3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the battery will be drained soon.

4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of MinTime/MaxTime calculation is started.

6. Installation

This product comes with waterproof function. When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall

with screws.

Note: When installing the battery, use a screwdriver or similar tool to assist in opening the battery cover.

Waterline Structure:

Installation Suggestions and Examples

Water line: up to 300m*

Water contact alarm: recommended at least

3cm line length

Alert: Instant report (within 10 seconds)

**The length of the accessory water measuring line has been setted at the factory. If the water measuring line

setting is manual, users need to set the water line length in the host before using it.**

7. Important Maintenance Instruction

Your device is a product of superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty

service effectively.

• Keep the equipment dry. Rain, moisture, and various liquids or moisture may contain minerals that can corrode electronic circuits. In case the device

is wet, please dry it completely.

• Do not use or store in dusty or dirty areas. This can damage its detachable parts and electronic components.

• Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.

• Do not store in a cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside, which will destroy the board.
