OpenDTU Build cpplint Yarn Linting
If you are upgrading from a version before 15.03.2023 you have to upgrade the partition table of the ESP32. Please follow the this documentation!
This project was started from this discussion (Mikrocontroller.net). It was the goal to replace the original Hoymiles DTU (Telemetry Gateway) with their cloud access. With a lot of reverse engineering the Hoymiles protocol was decrypted and analyzed.
The documentation can be found here. Please feel free to support and create a PR in this repository to make the documentation even better.
