## 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.
|
|
|
|

## State of the project
|
|

|
|
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](https://www.mikrocontroller.net/topic/525778). 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](https://github.com/tbnobody/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.
