Async Python client for NRGkick Gen2 EV charger local REST API

nrgkick-api

Async Python client for NRGkick Gen2 EV charger local REST API.

Overview

This library provides an async Python interface for communicating with NRGkick Gen2 EV chargers via their local REST JSON API. It is designed to be used with Home Assistant but can be used standalone in any async Python application.

Features

• Async/await support - Built on aiohttp for efficient async I/O
• Automatic retry logic - Handles transient network errors with exponential backoff
• Authentication support - Optional HTTP Basic Auth
• Type hints - Full type annotation for better IDE support
• Minimal dependencies - Only requires aiohttp

Installation

pip install nrgkick-api

Quick Start

import asyncio
import aiohttp
from nrgkick_api import NRGkickAPI

async def main():
    async with aiohttp.ClientSession() as session:
        api = NRGkickAPI(
            host="192.168.1.100",
            username="admin",  # Optional
            password="secret",  # Optional
            session=session,
        )

        # Get device information
        info = await api.get_info()
        print(f"Device: {info['general']['device_name']}")
        print(f"Serial: {info['general']['serial_number']}")

        # Get current values
        values = await api.get_values()
        print(f"Power: {values['powerflow']['total_active_power']}W")

        # Control charging
        await api.set_current(16.0)  # Set to 16A
        await api.set_charge_pause(True)  # Pause charging

asyncio.run(main())

API Reference

NRGkickAPI

The main client class for communicating with NRGkick devices.

Constructor

NRGkickAPI(
    host: str,
    username: str | None = None,
    password: str | None = None,
    session: aiohttp.ClientSession | None = None,
)

• host: IP address or hostname of the NRGkick device
• username: Optional username for HTTP Basic Auth
• password: Optional password for HTTP Basic Auth
• session: aiohttp ClientSession (required for making requests)

Methods

Method	Description
get_info(sections=None)	Get device information
get_control()	Get current control parameters
get_values(sections=None)	Get real-time telemetry data
set_current(current)	Set charging current (6.0-32.0A)
set_charge_pause(pause)	Pause/resume charging
set_energy_limit(limit)	Set energy limit in Wh (0=unlimited)
set_phase_count(phases)	Set phase count (1-3)
test_connection()	Test device connectivity

Exceptions

Exception	Description
NRGkickError	Base exception for all NRGkick errors
NRGkickConnectionError	Network/communication errors
NRGkickAuthenticationError	Authentication failures (401/403)

API Endpoints

The library communicates with three main endpoints:

• /info - Device information (serial, model, versions, etc.)
• /control - Control parameters (current, pause, limits)
• /values - Real-time telemetry (power, energy, temperatures)

Requirements

• Python 3.11+
• aiohttp 3.8.0+
• NRGkick Gen2 with JSON API enabled

Enabling the JSON API

The local REST API must be enabled in the NRGkick mobile app:

1. Open the NRGkick app
2. Connect to your device
3. Navigate to Settings → JSON API
4. Enable the API
5. Optionally configure authentication
