Introduction
R711A is a long distance wireless temperature sensor based on LoRaWANTM protocol (Class A). It is compatible with LoRaWAN protocol.
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.

Set up Instruction
On/Off
Power on
| Insert batteries. (Open the battery back cover and insert two 1.5V AA batteries into the
battery slot)
---|---
Turn on| Press and hold the function key till the green indicator flashes
once.
Turn off (Restore to factory setting)| Press and hold the function key for 5
seconds and the green indicator flashes 20 times.

Note
| 1. After insert batteries and press the button at the same time, the device will be in engineering test mode.
2. After remove and insert the battery, the device will remember the previous on/off status by default.
3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
Network Joining
Never joined the network
| Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success The green indicator remains off: fail
---|---
Had joined the network
(Not restore to factory setting)
| Turn on the device to search the previous network to join. The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network
| Suggest checking the device registration information on the gateway or consulting your
platform server provider if the device fails to join the network.
Function Key
Press and hold for 5 seconds
| Restore to factory setting / Turn off
The green indicator flashes 20 times: success The green indicator remains off: fail
---|---
Press once
| The device is in the network: The green indicator flashes once and sends a data report
The device is not in the network: The green indicator remains off
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.

Data Report
The device will immediately send a version package report and a data report including the voltage and temperature. The device sends data according to the default configuration before any other configuring
Default setting:
-
Maxime: Max Interval = 60min = 3600s
-
MinTime: Min Interval = 60min = 3600s
-
Temperature Change: = 0x0064 (1 ℃)
-
Battery Change: = 0x01 (0.1V)
Note:- The cycle of the device sending the data report is according to the default.
- The interval between two reports must be in time.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.
Data report configuration and sending period are as following:

- Command Configuration: MinTime = 1min, MaxTime = 1min, BatteryChange = 0.1v, TemperatureChange = 1℃
- Downlink： 01BC003C003C0100640000, 003C(Hex) = 60(Dec) ,0064(Hex) = 100(Dec)

Example for MinTime/MaxTime logic:
-
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V
Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange value.
-
Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
-
Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
Notes:
- The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
- The data collected is compared with the last data reported. If the data change value 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.
- 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.
- 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.
Installation
This product does not have a waterproof function. After the join into LoRa network, please place it indoors.
-
Please screw the bracket into the wall.

Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
- Keep the equipment dry. Rain, moisture and various liquids or water 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 way can damage its detachable parts and electronic components.
- Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
- Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board.
- Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
- Do not wash with strong chemicals, detergents or strong detergents.
- Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
- Do not throw the battery into the fire to prevent the battery from exploding.
- Damaged batteries may also explode. All the above suggestions apply equally to your device, batteries and accessories. If any device is not operating properly. Please take it to the nearest authorized service facility for repair.
