official release builds are built from branch master, as the respective tags point to commits in branch master (only). to check whether or not a new version is available, we should check branch master for new commits. checking against HEAD does not work as expected, at least in the OpenDTU-OnBattery repo, since its default branch is "development", not "master". usually, there should be no commits on master in between releases, so we will now only show "update available" if a new release was made. this is not foolproof, but should work as long as we keep "master" clean. for builds from other branches, the comparison is perfomed against the respective branch. if a user installed a binary built by github actions based on a development branch, the user will see "update available" if new commits were added to the development branch since. for other branches, also pull request builds, the test for updates will fail as the branch name shown in the system info is not actually a branch name, e.g., "helgeerbe/OpenDTU-OnBattery/pr1183-202408212043". |

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.

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.
Acknowledgment
A special Thank to Thomas Basler (tbnobody) the author of the original OpenDTU project. You are doing a great job!
@helgeerbe: Last but not least, I would like to thank all the contributors. With your ideas and enhancements, you have made OpenDTU-OnBattery much more than I originally had in mind.
