560370281f perf(prediction): optional SciPy-free evaluation of the self-consumption tables (#1378)
* perf(prediction): evaluate self-consumption tables without SciPy

The GENETIC inverter (and the GENETIC0 one) evaluates a pickled
scipy.interpolate.RegularGridInterpolator for the self-consumption
probabilities. SciPy is used nowhere else in EOS, yet loading it costs
about 35 MB RSS (21 MB anonymous) on Linux arm64, which every
optimization run pays.

Add utils/gridinterpolator.py:

- LinearGridInterpolator: 2-D linear interpolation with the same steps
  as SciPy's linear 2-D path (interval search, normalised distances,
  corner weights summed in the same order, fill value outside the grid,
  NaN for NaN input).
- load_grid_interpolator(): reads the shipped pickles with a restricted
  unpickler that maps the SciPy class to a stand-in and accepts only
  the NumPy globals needed for the arrays. SciPy is not imported, and
  the data files no longer depend on SciPy's private module paths.

Results are bit-identical to SciPy on Linux (aarch64, checked on 3.6M
points per table including the query pattern of the inverter). The
macOS arm64 SciPy wheel fuses multiply-add, so there SciPy itself
differs by <= 1.1e-16; GENETIC plans for fixed seeds are unchanged on
both platforms.

* feat(prediction): make the SciPy-free table evaluation opt-in

Add optimization.self_consumption_interpolator (scipy | numpy, default scipy).
The default keeps evaluating the self-consumption tables with SciPy's
RegularGridInterpolator, built from the same grid, values and fill value the
pickle holds, so results are unchanged. With numpy the tables are evaluated by
LinearGridInterpolator and SciPy is never imported. The backend is read on
every evaluation, so a config change applies to the next run.

AkkudoktorEOS AkkudoktorEOS

Build optimized energy management plans for your home automation

AkkudoktorEOS is a comprehensive solution for simulating and optimizing energy systems based on renewable sources. Optimize your photovoltaic systems, battery storage, load management, and electric vehicles while considering real-time electricity pricing.

Why use AkkudoktorEOS?

AkkudoktorEOS can be used to build energy management plans that are optimized for your specific setup of PV system, battery, electric vehicle, household load and electricity pricing. It can be integrated into home automation systems such as NodeRED, Home Assistant, EVCC.

🏘️ Community

We are an open-source community-driven project and we love to hear from you. Here are some ways to get involved:

What do people build with AkkudoktorEOS

The community uses AkkudoktorEOS to minimize grid energy consumption and to maximize the revenue from grid energy feed in with their home automation system.

Why not use AkkudoktorEOS?

AkkudoktorEOS does not control your home automation assets. It must be integrated into a home automation system. If you do not use a home automation system or you feel uncomfortable with the configuration effort needed for the integration you should better use other solutions.

Quick Start

Upgrading an existing installation?

The next release includes a substantial energy-planning update: 15-minute GENETIC plans, EV departure targets, flexible household loads, optional battery export, and better measurement and PV-forecast tools. These features are currently unreleased.

Existing Home Assistant automations, Node-RED flows and custom API clients may need changes. Devices now use stable IDs, the new optimizer reads hardware settings from EOS configuration, and incomplete forecasts or outdated battery measurements can stop a run. The legacy POST /optimize remains available with GENETIC0; the new POST /v1/optimize has a different request format. Back up your configuration and data before updating.

Read the upgrade guide and changelog before switching an existing installation.

Start with Docker

Run EOS with Docker (access dashboard at http://localhost:8504):

docker run -d \
  --name akkudoktoreos \
  -p 8503:8503 \
  -p 8504:8504 \
  -e OPENBLAS_NUM_THREADS=1 \
  -e OMP_NUM_THREADS=1 \
  -e MKL_NUM_THREADS=1 \
  -e EOS_SERVER__HOST=0.0.0.0 \
  -e EOS_SERVER__EOSDASH_HOST=0.0.0.0 \
  -e EOS_SERVER__EOSDASH_PORT=8504 \
  --ulimit nproc=65535:65535 \
  --ulimit nofile=65535:65535 \
  --security-opt seccomp=unconfined \
  akkudoktor/eos:latest

System Requirements

  • Python: 3.11 or higher
  • Architecture: amd64, aarch64 (armv8)
  • OS: Linux, Windows, macOS

Note

: Other architectures (armv6, armv7) require manual compilation of dependencies with Rust and GCC.

Installation

Home Assistant add-on

Supports aarch64 Architecture Supports amd64 Architecture

To install the Akkudoktor-EOS add-on in Home Assistant:

Open your Home Assistant instance and show the add add-on repository dialog with a specific repository URL pre-filled.

  1. Add the repository URL:

    In Home Assistant, go to:

    Settings → Add-ons → Add-on Store → ⋮ (top-right menu) → Repositories
    

    and enter the URL of this Git repository:

    https://github.com/Akkudoktor-EOS/EOS
    
  2. Install the add-on:

    After adding the repository, the add-on will appear in the Add-on Store. Click Install.

  3. Start the add-on:

    Once installed, click Start in the add-on panel.

  4. Access the dashboard:

    Click Open Web UI in the add-on panel.

  5. Configure EOS (optional): In the dashboard, go to:

    Config
    
docker pull akkudoktor/eos:latest
docker compose up -d

Access the API at http://localhost:8503 (docs at http://localhost:8503/docs)

From Source

git clone https://github.com/Akkudoktor-EOS/EOS.git
cd EOS

Linux:

python -m venv .venv
.venv/bin/pip install -r requirements.txt
.venv/bin/pip install -e .
.venv/bin/python -m akkudoktoreos.server.eos

Windows:

python -m venv .venv
.venv\Scripts\pip install -r requirements.txt
.venv\Scripts\pip install -e .
.venv\Scripts\python -m akkudoktoreos.server.eos

Configuration

EOS uses EOS.config.json for configuration. If the file doesn't exist, a default configuration is created automatically.

Custom Configuration Directory

export EOS_DIR=/path/to/your/config

Configuration Methods

  1. EOSdash (Recommended) - Web interface at http://localhost:8504
  2. Manual - Edit EOS.config.json directly
  3. API - Use the Server API

See the documentation for all configuration options.

Port Configuration

Default ports: 8503 (API), 8504 (Dashboard)

If running on shared systems (e.g., Synology NAS), these ports may conflict with system services. Reconfigure port mappings as needed:

docker run -p 8505:8503 -p 8506:8504 ...
