## !! IMPORTANT UPGRADE NOTES !!

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](docs/UpgradePartition.md) documentation!

## Background

This project was started from [this](https://www.mikrocontroller.net/topic/525778) 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.

## Documentation

The documentation can be found [here](https://tbnobody.github.io/OpenDTU-docs/).
Please feel free to support and create a PR in [this](https://github.com/tbnobody/OpenDTU-docs) repository to make the documentation even better.
