No project description provided

pyteleinfo

A Python library for decoding and encoding ENEDIS teleinfo frames - implementation of the tele-information communication frames specifications for French electronic electricity meters.

Features

• Decode teleinfo frames from French ENEDIS electricity meters
• Encode data back to teleinfo format
• Read frames from serial port with configurable settings
• Async I/O support with pyserial-asyncio-fast
• Comprehensive exception handling
• Pydantic-based settings with environment variable support

Installation

pip install pyteleinfo

Quick Start

Decoding Teleinfo Frames

from teleinfo import decode

# Decode a raw teleinfo frame (bytes or string)
raw_frame = b'\x02\nADCO 050022120078 2\r\nOPTARIF HC.. <\r\x03'
decoded = decode(raw_frame)
print(decoded)
# [{'label': 'ADCO', 'data': '050022120078'}, {'label': 'OPTARIF', 'data': 'HC..'}]

Reading from a Serial Port

from teleinfo import read_frame, decode

# Read a complete frame from the serial port
raw = read_frame("/dev/ttyUSB0")
decoded = decode(raw)
print(decoded)

Settings can be customized via the TeleinfoSettings class or environment variables (prefixed with TELEINFO_, e.g. TELEINFO_BAUDRATE=1200):

from teleinfo.settings import TeleinfoSettings

settings = TeleinfoSettings(baudrate=9600, timeout=10.0)
raw = read_frame("/dev/ttyUSB0", settings=settings)

Requirements

• Python >= 3.12
• pyserial >= 3.5
• pyserial-asyncio-fast
• pydantic-settings >= 2.13.1
