1. Introduction The R718B1 series is a Wireless Resistance Temperature Detector for Netvox ClassA type devices based on the LoRaWAN open protocol and is compatible with the LoRaWAN protocol. R718B connects an external resistance temperature detector (PT1000) to measures the temperature.
Applicable to third-party platforms: Actility/ThingPark, TTN, MyDevices/Cayenne Low power consumption and long battery life Battery Life: ⁻ Please refer to web: http://www.netvox.com.tw/electric/electric_calc.html ⁻ At this website, users can find battery life time for variety models at different configurations.
4. Set up Instruction On/Off Power on Insert batteries. (Users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds till the green indicator flashes once. Turn off (Restore to factory setting) Press and hold the function key for 5 seconds till green indicator flashes for 20 times. Power off Remove Batteries.
The device report interval will be programmed based on the default firmware which may vary. The interval between two reports must be the minimum time. Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://cmddoc.netvoxcloud.com/cmddoc to resolve uplink data.

5.3 Example for MinTime/MaxTime logic Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V MaxTime MaxTime Sleeping(MinTime) Sleeping(MinTime) Wake up and collects data Wakes up and collects data Wakes up and collects data REPORTS 3.6V REPORTS 3.6V REPORTS 3.6V Note: MaxTime=MinTime.
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.
7. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.
