hyxi-cloud-api

An asynchronous Python client for interacting with the HYXI Cloud API.

This library was primarily built to power the HYXI Cloud Home Assistant Integration, but it can be used in any Python 3.14+ project to fetch telemetry data from HYXI solar inverters and battery systems.

📦 Installation

You can install the package directly from PyPI:

pip install hyxi-cloud-api

🚀 Quick Start

This library uses aiohttp for non-blocking network requests. You will need to provide your Developer API credentials (AK/SK), along with an active aiohttp.ClientSession.

Note

The HYXI Open API requires a separate developer account registered at open.hyxicloud.com. If your developer email is different from your main HYXI app account, you must Share your Plant from the app to your developer email address to access your data.

import asyncio
import aiohttp
from hyxi_cloud_api import HyxiApiClient

async def main():
    # Replace with your actual HYXi Cloud credentials
    ACCESS_KEY = "your_access_key"
    SECRET_KEY = "your_secret_key"
    BASE_URL = "https://open.hyxicloud.com"

    async with aiohttp.ClientSession() as session:
        # 1. Initialize the client
        client = HyxiApiClient(
            access_key=ACCESS_KEY,
            secret_key=SECRET_KEY,
            base_url=BASE_URL,
            session=session
        )

        # 2. Fetch device data
        try:
            device_data = await client.get_all_device_data()
            print("Successfully fetched HYXi data:")
            print(device_data)
        except Exception as e:
            print(f"Error communicating with HYXi Cloud: {e}")

if __name__ == "__main__":
    asyncio.run(main())

HYXI Open API base URLs vary by region. The examples in this README use the Europe endpoint by default.

Node	Request Address
China	https://open-cn.hyxicloud.com
Europe (default)	https://open.hyxicloud.com
North America	https://open-or.hyxicloud.com

🔧 Device Control

You can control inverter operating modes directly through the API. This requires a device serial number, which you can obtain from the device data response above.

async def control_example(client, device_sn):
    # Set operating mode
    await client.set_mode_self_consume(device_sn)
    await client.set_mode_charge(device_sn, watts=3000)
    await client.set_mode_discharge(device_sn, watts=2500)
    await client.set_mode_idle(device_sn)

    # Peak shaving (close, charge, discharge, stop, hold)
    await client.set_peak_shaving(device_sn, action="charge")

    # Frequency control
    await client.set_frequency_control(device_sn, enabled=True)

Control failures raise HyxiApiClient.ControlError:

try:
    await client.set_mode_charge(device_sn, watts=3000)
except client.ControlError as e:
    print(f"Control command failed: {e}")

🔔 Subscriptions

You can subscribe a callback URL to HYXI push notifications for real-time data, alarms, and FCAS/frequency-modulation real-time data.

async def subscription_example(client):
    callback_url = "https://your-public-callback-host/hyxi/callback"
    device_sns = ["60700000000001", "60700000000002"]

    real_time = await client.subscribe_real_time_data(
        callback_url,
        device_sns,
        post_rate=60000,  # milliseconds, 5000-3600000
    )

    alarm = await client.subscribe_alarm(
        callback_url,
        device_sns,
        post_rate=60000,  # milliseconds, 5000-3600000
    )

    fcas = await client.subscribe_fm_real_time_data(
        callback_url,
        device_sns,
        post_rate=1,  # hours, 1-6
    )

    await client.cancel_subscription(real_time["data"]["subscribeCode"])

Subscription failures raise HyxiApiClient.SubscriptionError.

🛠️ Requirements

• Python 3.14 or newer
• aiohttp >= 3.13.3

🔐 Privacy & Debug Logging

When debug logging is enabled, this library automatically masks sensitive identifiers before writing them to the log — no manual redaction needed.

Field	Behaviour
Serial numbers (deviceSn, parentSn, batSn)	Hashed securely using SHA-256 (first 8 chars shown) to enable deterministic cross-device tracing without exposing the original identifier, e.g. e3b0c442
Plant IDs (plantId)	Same SHA-256 hashing format
Home/site address (plantAddress)	Fully redacted → [REDACTED]
IMEI (gprsImei)	Same SHA-256 hashing format

Masking is deterministic, so parent/child device relationships remain traceable across log lines.
