Netvox R816B LoRaWAN decoder and payload format
The Netvox R816B is a LoRaWAN current and energy meter that reports current, energy and voltage. It works from -10 to 50 °C.
Payload format
An uplink from the device as it arrives at the network server, and what the official decoder returns for it. Examples come from the decoder's own test cases.

Connect it to Cloud Studio IoT
- 1
Register the device in your network server
Add it to The Things Stack, ChirpStack, Actility ThingPark or LORIOT with its DevEUI, JoinEUI and AppKey and the frequency plan of your region.
- 2
Apply the decoder
In The Things Stack, pick the model from the device repository and its decoder is applied for you. In ChirpStack v4, paste the official decoder as the device profile's JavaScript codec.
- 3
Connect the network server to Cloud Studio IoT
Set up the integration once per network server; every device registered there then reaches Cloud Studio IoT with its decoded values.
- 4
Build dashboards and alarms
The decoded fields become device variables for dashboards, alarms by email or SMS, and scheduled reports.
