b59012c1f7 fix(database): open backend so records actually persist and reload (#1209)
* fix(database): open backend so records actually persist and reload

Measurement and prediction records were never persisted to the
configured database backend (e.g. LMDB). They only survived while the
process was running; every restart lost the accumulated history. For
LoadAkkudoktorAdjusted this silently zeroed the measurement-based
adjustment (the adjusted load forecast collapsed onto the raw mean).

Root cause: `db_enabled` is defined as `database.is_open`, and every
database code path (initialization, load, save, insert) is guarded behind
`db_enabled`. Nothing ever opened the backend first -- the only lazy open
(via `_run_db`) was unreachable because those calls sit behind the same
guard. The backend therefore stayed closed, `db_enabled` stayed False,
and all writes fell through to the JSON file fallback, which only holds
the current in-memory snapshot and is not reloaded into the record store
on startup.

Fix: explicitly open the configured backend in `_db_ensure_initialized`
before the `db_enabled` gate, wrapped in try/except so a failure degrades
gracefully to file storage.

Verified via an A/B test (identical persisted config, push -> save ->
restart): without the fix the backend reports enabled=false and data is
lost on restart; with the fix the backend is enabled, records persist to
LMDB, and reload correctly after restart.

* fix(database): skip disabled providers and avoid open retry loop

Address review feedback:
- Skip opening the backend for disabled providers (None/"NoDB"), whose
  is_open is always False and would otherwise be reopened on every call.
- Add a one-shot _db_open_attempted flag so a closed/failed backend is not
  retried (and re-logged) on every record operation.
- Add tests covering that NoDB never calls open() and that an unavailable
  backend does not raise per operation and is opened at most once.

* fix(database): drop file-storage-fallback wording from open failure log

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

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 ...

API Documentation

Interactive API docs available at:

  • Swagger UI: http://localhost:8503/docs
  • OpenAPI Spec: View Online
