Introduction
The R831D is a Wireless Relay Switch Control device for Netvox Class C type devices based on the LoRaWAN open protocol and is
compatible with the LoRaWAN protocol.
R831D is designed to control switch devices, mainly for electrical appliances. R831D allows you to connect and control 3 buttons
and 3 dry contacts. The connected buttons and dry contacts will not affect each other. It will report 3 relay status and 3 input status.
LoRa Wireless Technology:
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It can
be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic meter
reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size, low power
consumption, long transmission distance, strong 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.
