pysaj-elekeeper 0.0.7

Python client for the SAJ Elekeeper API

PySaj

Async Python client for the current SAJ Elekeeper API at https://eop.saj-electric.com/.

Looking for testers! PySaj has been validated against SAJ inverters with serial prefixes R5X (on-grid) and ASS (AC-coupling with battery). If you have a different SAJ device and are willing to test, please open an issue — your feedback helps expand coverage.

PySaj targets the newer Elekeeper web API (/dev-api/api/v1/...) used by the current SAJ portal. It does not use the legacy /saj/login cookie flow.

Status

This package is in alpha. The implemented endpoints have been validated against a real Elekeeper account, but the upstream API is private and can change without notice.

Features

• Async httpx client.
• Elekeeper-compatible AES password encryption.
• Elekeeper-compatible request signing.
• Login, refresh token, and logout helpers.
• Plant list and plant detail helpers.
• Power flow, energy statistics, battery, device, weather, and chart helpers.
• Raw authenticated GET and POST helpers for endpoints not wrapped yet.
• CLI discovery sample with JSONL output.
• CLI plant summary focused on relevant daily values.

Installation

From GitHub:

python -m pip install pysaj-elekeeper

From a local checkout:

git clone https://github.com/giovadroid/pysaj.git
cd pysaj
uv sync --extra dev

Editable install without uv:

python -m venv .venv
. .venv/bin/activate
python -m pip install -e ".[dev]"

Credentials

Create a local .env file from the example:

cp .env.example .env

Then fill:

SAJ_USER=[e-mail]
SAJ_PASS=your-password
SAJ_BASE_URL=https://eop.saj-electric.com

Library Usage

High-level API for normal integrations:

import asyncio
import os

from pysaj import SajClient


async def main() -> None:
    async with SajClient() as client:
        await client.authenticate(os.environ["SAJ_USER"], os.environ["SAJ_PASS"])
        overview = await client.get_plant_overview()
        # Or select explicitly:
        # overview = await client.get_plant_overview(plant_name="Home")
        # overview = await client.get_plant_overview(plant_uid="...")

        print(overview.name)
        print(overview.pv_power_w)
        print(overview.battery_soc_percent)


asyncio.run(main())

Lower-level endpoint wrappers are also available when you need raw Elekeeper payloads:

import asyncio
import os

from pysaj import SajClient


async def main() -> None:
    async with SajClient() as client:
        await client.login(os.environ["SAJ_USER"], os.environ["SAJ_PASS"])

        first = await client.get_primary_plant()
        if first is None:
            return
        plant_uid = first["plantUid"]

        device_sn = await client.get_primary_device_sn(plant_uid)

        flow = await client.get_device_energy_flow(plant_uid, device_sn=device_sn)
        battery = await client.get_one_device_battery_info(device_sn) if device_sn else {}

        print(flow.get("totalPvPower"), battery.get("batEnergyPercent"))


asyncio.run(main())

CLI Examples

Both examples read credentials from a .env file in the current directory:

cp .env.example .env
# edit SAJ_USER and SAJ_PASS

Discovery sample

python examples/sample.py
python examples/sample.py --jsonl pysaj-sample.jsonl

Logs in, lists plants, fetches the first plant's detail, device, battery, weather, and chart endpoints. Prints a compact discovery summary and writes full endpoint payloads to JSONL.

Plant summary

python examples/plant_summary.py
python examples/plant_summary.py --plant-uid <plant-uid>
python examples/plant_summary.py --plant-name <plant-name>

Prints relevant daily plant values:

• Current PV, load, grid, and battery power flow.
• Today's production, load, import, export, battery charge, and battery discharge.
• Lifetime plant totals.
• Battery SOC, SOH, voltage, current, temperature, and work time.
• Device rows with current power, daily production, and SOC where available.

Wrapped Endpoints

Auth and account:

• authenticate
• login
• refresh_access_token
• logout
• get_login_info

Plants and home statistics:

• list_plants
• get_primary_plant
• get_plant_by_uid
• get_plant_by_name
• get_primary_device_sn
• get_plant_overview
• get_end_user_plant_list
• get_plant_list
• get_plant_info
• get_plant_parallel_info
• get_device_energy_flow
• get_home_energy_statistics
• get_home_power_statistics
• get_home_plant_statistics
• get_plant_statistics_data
• get_home_battery_statistics
• get_home_device_statistics

Devices and battery:

• get_device_list
• get_battery_list
• get_one_device_info
• get_one_device_battery_info
• get_order_status_summary_report_info

Weather and charts:

• get_current_weather
• get_forecast_weather
• get_self_use_energy_data
• get_store_power_analysis_data
• get_store_energy_compare_data
• get_store_energy_balance_data
• get_grid_curve_analysis_data
• get_grid_energy_statistics_data

Escape hatches:

• get_raw
• post_raw

Known Limitations

• getPlantSankeyDiagram returned upstream errCode=10001 for the tested account and is intentionally not called by the sample.
• Some endpoints require deviceSn; for the tested plant this came from get_plant_info()["deviceSnList"][0].
• Some dashboard endpoints use searchOfficeIdArr, available from get_login_info()["officeId"].

GitHub Actions:

• CI validates lint, tests, and package build on pushes and pull requests.
• Release builds GitHub Release artifacts when pushing a SemVer tag such as v0.1.0.
• Publish to PyPI is manual and uses PyPI Trusted Publishing. It is included for later use, but GitHub releases are the default publishing path for now.
