This changes the custom current limit so the custom limit is only applied when any of: - SoC is valid and not ignored and SoC < threshold - Voltage is valid and Voltage < threshold - Voltage is invalid Independently, if "Use Battery-Reported limit" is enabled and valid, it is applied (unless a lower custom limit already was applied). |

OpenDTU-OnBattery
This is a fork of OpenDTU.
What is OpenDTU-OnBattery
OpenDTU-OnBattery is an extension of the original OpenDTU to support battery chargers, battery management systems (BMS) and power meters on a single ESP32. With the help of a Dynamic Power Limiter, the power production can be adjusted to the actual consumption. In this way, it is possible to implement a zero export policy.
Documentation
The canonical documentation of OpenDTU-OnBattery is hosted at https://opendtu-onbattery.net.
You may find additional helpful information in the project's community-maintained Github Wiki.
To find out what's new or improved have a look at the changelog of the releases.
State of the project
OpenDTU-OnBattery is actively maintained. Please note that OpenDTU-OnBattery may change significantly during its development. Bug reports, comments, feature requests and pull requests are welcome!
History of the project
The original OpenDTU project was started from a discussion on Mikrocontroller.net. It was the goal to replace the original Hoymiles DTU (Telemetry Gateway) to avoid using Hoymile's cloud. With a lot of reverse engineering the Hoymiles protocol was decrypted and analyzed.
In the summer of 2022 @helgeerbe bought a Victron MPPT charge cntroller, and didn't like the idea to set up a separate ESP32 to receive the charger's data. He decided to fork OpenDTU and extend it with battery charger support and a Dynamic Power Limiter.
In early October 2024, the project moved to the newly founded GitHub
organisation hoylabs and is since maintained by multiple community members.
Acknowledgments
- Special thanks to Thomas Basler (@tbnobody), the author of the upstream project, for hist continued effort!
- Thanks to @helgeerbe for starting OpenDTU-OnBattery and his dedication to the
project, as well as his trust in the current maintainers of the project,
which act as part of the
hoylabsGitHub organisation. - We like to thank all contributors. With your ideas and enhancements, you have made OpenDTU-OnBattery much more than @helgeerbe originally had in mind.
