energy-counters 1.2.2

A Python library for reading data from various electrical energy counters including Carlo Gavazzi, Contrel, Diris, Lovato, RedZ, and Schneider devices

Energy Counters Library

A Python library for reading data from various electrical energy counters including Carlo Gavazzi, Contrel, Diris, Lovato, RedZ, and Schneider devices.

Features

• Multiple Communication Protocols: Support for both Modbus RTU (serial) and Modbus TCP connections
• Automatic Fallback: Intelligent switching between TCP and RTU when both are configured
• Comprehensive Data Collection: Read voltage, current, power, energy, and frequency measurements
• Easy Configuration: Simple dataclass-based configuration for counters and connections
• Detailed Logging: Built-in logging for debugging and monitoring
• Modern Python: Written for Python 3.8+ with type hints and dataclasses
• Extensible Design: Easy to add support for new counter models

Installation

Install from PyPI:

pip install energy-counters

Or for development:

pip install -e .

Quick Start

Import the library

import energy_counters
from energy_counters.carlo_gavazzi import EM530DataCollector
from energy_counters.lovato import DMG210DataCollector
# ... other counters

Basic Usage Example

from energy_counters.carlo_gavazzi import (
    CounterConfiguration,
    ModbusTCPConfiguration,
    EM530DataCollector
)

# Configure the counter
counter_config = CounterConfiguration(
    counter_id=167,
    unit_id=100,
    counter_name="TestCounter",
    company_id="MyCompany"
)

# Configure Modbus TCP connection
tcp_config = ModbusTCPConfiguration(
    host="192.162.10.10",
    port=502
)

# Create collector and read data
collector = EM530DataCollector(counter_config, modbus_tcp_config=tcp_config)
if collector.connect():
    data = collector.collect_data()
    if data:
        print(f"Voltage L1: {data['voltageL1']}V")
        print(f"Current L1: {data['currentL1']}A")
        print(f"Active Power: {data['activePower']}kW")
    collector.disconnect()
