How to Decode the Payload of Your Device
What is payload decoding?
Let's start with the basics. In essence, payload decoding is the process of translating raw data received from a device into readable, structured data. During this conversion, packets of data, typically transmitted in hexadecimal format, are decoded into human-readable values, such as humidity or temperature readings.
Why is it essential for LPWAN technologies?
LPWAN connectivity technologies such as LoRaWAN and Sigfox are well suited for low-power IoT solutions in which small amounts of data need to be sent at regular intervals. These are perfect for smart applications in which IoT devices are operating autonomously for extended periods (possibly years) and sending their data periodically to the cloud.
To reduce energy consumption and keep the data packets as small as possible, LPWAN devices send their data via a payload encoded in hexadecimal format. This differs from other protocols that define standard data payload formats and communicate through structured data such as JSON or XML.
The result is that countless device manufacturers in the IoT market define their own payload formats for their particular sensors. For someone who wants to integrate different sensors in one IoT solution, this translates into effort invested in encoding/decoding the data when setting up the project.
Towards a dictionary of IoT devices
This bothersome data parsing process should not be left solely on the shoulders of the IoT project leader. This is why we offer a device type library to ease the payload encoding/decoding process.
The akenza Device Type Library hosts an extensive list of standard device types to ease the registration of new devices into an IoT project by taking care of the data parsing automatically.
For each device type, we offer a detailed description of the sensor's capabilities and measurement values. This also means that the Device Type Library can be used as a valuable reference to select the appropriate sensors for a particular use case and guide the purchase of new devices.
Thanks to the no-code Data Flow of akenza, you can directly use those device types inside your project in a few clicks. Just select the right connectivity for your device, pick the desired device type in our library and select the output connector defining where the data shall be stored. You are now ready to register your device and start collecting data.
