IOmeter Python Client

A Python client for interacting with IOmeter devices over HTTP. This client provides an async interface for reading energy consumption/production data and monitoring device status.

Features

• 🔌 Asynchronous communication with IOmeter bridge over HTTP
• 📊 Read energy consumption and energy production data
• 🔋 Monitor device status including battery level and signal strength
• 🔄 Two transport modes: polling (IOmeterClient) and Server-Sent Events (IOmeterSSEClient)

Quick Start

Installation

pip install iometer

Polling

Use IOmeterClient to fetch readings on demand:

from iometer import IOmeterClient

async def check_meter_reading():
    async with IOmeterClient("192.168.1.100") as client:
        reading = await client.get_current_reading()
        print(f"Consumption: {reading.get_total_consumption()} Wh")
        print(f"Production: {reading.get_total_production()} Wh")
        print(f"Current Power: {reading.get_current_power()} W")

Server-Sent Events (SSE)

Use IOmeterSSEClient to receive readings as they arrive (push-based):

from iometer import IOmeterSSEClient
from aiohttp import ClientSession

async def stream_readings():
    async with ClientSession() as session:
        client = IOmeterSSEClient("192.168.1.100", session=session)
        async for reading in client.watch_readings():
            print(f"Consumption: {reading.get_total_consumption()} Wh")
            print(f"Current Power: {reading.get_current_power()} W")

Device Status Information

from iometer import IOmeterClient

async def check_device_status():
    async with IOmeterClient("192.168.1.100") as client:
        # Get current status
        status = await client.get_current_status()
        
        # Bridge information
        print(f"Bridge Version: {status.device.bridge.version}")
        print(f"Bridge Signal: {status.device.bridge.rssi} dBm")
        
        # Core information
        core = status.device.core
        print(f"Connection: {core.connection_status}")
        print(f"Power Mode: {core.power_status}")
        
        if core.power_status.value == "battery":
            print(f"Battery Level: {core.battery_level}%")
