Python-CayenneLPP

Introduction

Open-source library for python to decode CayenneLPP format payload. The Cayenne Low Power Payload (LPP) provides a convenient and easy way to send data over LPWAN networks such as LoRaWAN. More details on CayenneLPP payload: https://github.com/myDevicesIoT/cayenne-docs

Note: while Python versions 2.7 and <=3.7 may work, they're not officially supported since they're EOL.

Installation

To install the package use next pip command

pip install python-cayennelpp

Usage

To decode payload simply use method decode() from this package

>>>from python_cayennelpp.decoder import decode
>>>print(decode('03670110056700FF'))
[{'channel': 3, 'name': 'Temperature Sensor', 'value': 27.2}, {'channel': 5, 'name': 'Temperature Sensor', 'value': 25.5}]

Additional info

The package may raise following exceptions:

• TypeError - if the provided data is not of the str type
• ValueError - if the provided data length is not equal to the expected

Note: if the package receives a wrong sensor type the intermediate result of the decoder will be returned, error printed to the stdout, but KeyError exception will not be raised
