1. Introduction
R313WA is a Class Awireless 2-gang seat occupancy device based on standard LoRaWAN protocol. The R313WA will report to the
gateway whenever one of the 2-gang seat occupancy sensor detects external pressure. It will also report to the gateway when the
external pressure is gone.
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.

4. Set up Instruction
On/Off
Power on Insert batteries.
Note: Insert two sections of 3V CR2450 button batteries and close the battery cover.
Turn on Press any function key till green and red indicator flashes once.
Turn off (Restore to factory setting) Press and hold both function keys for 5 seconds till green indicator flashes for 20
times.
Power off Remove Batteries.
Note:
1.Remove and insert the battery; the device memorizes previous on/off state by
default.
2.On/off interval is suggested to be about 10 seconds to avoid the interference of
capacitor inductance and other energy storage components.
3.Press any function key and insert batteries at the same time; it will enter engineer
testing mode.
Network Joining
Never joined the network
Turn on the device to search the network.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
Turn on the device to search the previous network.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network
(when the device is on)
Suggest to check the device verification information on the gateway with your
platform server provider.
Function Key
Press and hold for 5 seconds
Restore to factory setting / Turn off
The green indicator flashes for 20 times: success
The green indicator remains off: fail
Press once The device is in the network: green indicator flashes once and sends a report
The device is not in the network: green indicator remains off
Sleeping Mode
The device is on and in the
network
Sleeping period: Min Interval.
When the r
eportchange exceeds setting value or the state changes: send a data report
according to Min Interval.

5. Data Report
Data report configuration and sending period are as following:
Min Interval
(Unit:second)
Max Interval
(Unit:second) Reportable Change Current Change≥ Reportable Change
Current Change
＜
Reportable Change
Any number between
1~65535
Any number between
1~65535 Can not be 0. Report per Min Interval
Report
per Max Interval
When the device is turned on, it will immediately send a version package and attribute data.
Before any configuration is modified, the device sends data according to the default settings.
Default Setting:
Maximum time: 0x0E10 (3600s)
Minimum time: 0x0E10 (3600s)
BatteryChange: 0x01 (0.1V)
DisableTime: 0x001E (30s)// Value must be greater than DisableTime≧5s
DetectionTime: 0x0078 (120s) //Value must be greater than DetectionTime≧DisableTime
Pressure Detecting
：
When the R313WA detects changes in pressure, it will report the status.
When the seat is occupied, the status is 1.
When the seat is unoccupied, the status is 0.
Note:
The reported data is decoded by the Netvox LoRaWANApplication Command document and
http://www.netvox.com.cn:8888/cmddoc

Tips
1. Battery Voltage:
The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.
Battery=0x98, binary=1001 1000, if bit 7= 1, it means low voltage.
The actual voltage is 0001 1000 = 0x18 = 24, 24*0.1v =2.4v
2. Version Packet:
When Report Type=0x00 is the version packet, such as 015A000A0B202005200000, the firmware version is 2020.05.20
3. Data Packet:
When Report Type=0x01 is data packet.
