Encoder and Decoder for CayenneLLP

Project description

# PyCayenneLPP

[![Codacy Badge](](
[![Codacy Badge](](

A Cayenne Low Power Payload (CayenneLPP) decoder and encoder written in Python.
See also [myDevicesIoT/CayenneLPP](
for more information on the format and a reference implementation in C++.

The project is under active development. Releases will be published on the
fly as soon as a certain number of new features and fixes have been made.

## Getting Started

PyCayenneLPP does not have any external dependencies, but only uses builtin
functions and types of Python 3. At least Python in version 3.4 is required.

### Prerequisites

The PyCayenneLPP package is available via PyPi using `pip`. To install it run:

pip3 install pycayennelpp

### Usage Examples

The following show how to utilise PyCayenneLPP in your own application
to encode and decode data into and from CayenneLPP.

## Encoding

from cayennelpp import LppFrame

# create empty frame
frame = LppFrame()
# add some sensor data
frame.add_temperature(0, -1.2)
frame.add_humidity(6, 34.5)
# get byte buffer in CayenneLPP format
buffer = frame.bytes()

## Decoding

from cayennelpp import LppFrame

# byte buffer in CayenneLPP format with 1 data item
# i.e. on channel 1, with a temperature of 25.5C
buffer = bytearray([0x01, 0x67, 0x00, 0xff])
# create frame from bytes
frame = LppFrame().from_bytes(buffer)
# print the frame and its data
