Every morning before the day-ahead auction is published, /v1/prediction/update answered 400 and no prediction was produced at all. The provider asks for prices starting at the run day, because an existing history sets past_days to 0. The optimization horizon always reaches past the last published price, so an update is always considered necessary - and SMARD publishes the next day around midday. Between midnight and publication the requested window therefore contains nothing, and ElecPriceSMARD raised "SMARD response contains no usable day-ahead prices", which failed the whole prediction update rather than only that provider. ElecPriceEnergyCharts and its SMARD subclass now keep their existing history and let the ETS/median branch extrapolate the remaining slots, the same fallback FeedInTariffEnergyCharts already had. A cold start without any history stays fatal. ElecPriceSMARD also separates the two cases it used to conflate: a period the source has not published yet now reports the latest value it does have, and only a response without a single price still reads as unusable. Fixes the cache noise this produced as well. cache_in_file claimed its cache entry before calling the wrapped function, so a raising function left an empty file behind and every later call within the TTL logged "Read failed: Ran out of input" before refetching. The entry is now created only after the call returns.
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:
-
GitHub Issue Tracker: discuss ideas and features, and report bugs.
-
Akkudoktor Forum: get direct suppport from the community.
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.
- Andreas Schmitz, the Akkudoktor, uses EOS integrated in his NodeRED home automation system for OpenSource Energieoptimierung.
- Jörg, meintechblog, uses EOS for day-ahead optimization for time-variable energy prices. See: So installiere ich EOS von Andreas Schmitz
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.

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
- EOSdash (Recommended) - Web interface at
http://localhost:8504 - Manual - Edit
EOS.config.jsondirectly - 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 ...
