Bernhard Kirchen 983b58fa0c webapp: remove table's bottom margin
we don't need a margin at the bottom of tables in general. not sure why
this is even a thing in bootstrap. this change, in particular, makes the
space between a table and a parent card symmetric on all sides.

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 hoylabs GitHub 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.
