* Allow scaleValue() for 32bit values * Victron: Implement CAN message 0x360 This one-byte message is set to 0xff to request charging below a certain SoC threshold (10% in my tests). * Pytes: Add support for native CAN protocol The recently added PytesCanReceiver.cpp implements the Victron CAN protocol. This change additionally adds support for the native Pytes CAN protocol messages. Features only supported in Pytes protocol: - High-resolution state of charge / full and remaining mAh - Charge cycle counter - Balancing state Features only supported in Victron protocol: - FW version - Serial number Note that the only known way to select the native Pytes protocol is via the serial console (Cisco-compatible cables work): ``` login config setprt PYTES logout ``` to return to Victron protocol use: ``` login config setprt VICTRON logout ``` to return to DIP-switch based protocol setting: ``` login config setprt DIP logout ``` |

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.
