# Nulleinspeisung
|
|
|
|
## Overview
|
|
This project provides a Docker container (`denshooter/nulleinspeisung`) for managing solar energy systems. It's designed to optimize the use of energy generated by Hoymiles Wechselrichter, ensuring none of it is fed back into the grid. The container integrates with OpenDTU and Shelly 3EM Pro for effective energy management.

|
## Credits
|
|
This project is inspired by and based on [Selbstbau-PV's Hoymiles nulleinspeisung mit OpenDTU und Shelly3EM](https://github.com/Selbstbau-PV/Selbstbau-PV-Hoymiles-nulleinspeisung-mit-OpenDTU-und-Shelly3EM). Special thanks to the original authors for their foundational work.

|
- Docker installed
|
|
- The python script in this repo
|
|
|
|
### Configuration

|
|
1. **Serial Number**: Replace `<SERIAL_NUMBER>` with your Wechselrichter's serial number.
|
|
2. **Wechselrichter Output Range**: Set `maximum_wr` and `minimum_wr` for output range in Watts.
|
|
3. **OpenDTU Configuration**: Update `dtu_ip`, `dtu_user`, and `dtu_password` with your OpenDTU's details.
|
|
4. **Shelly IP**: Change `shelly_ip` to your Shelly 3EM Pro IP.
|
|

|
### Running the Container
|
|
Use the following command to run the container, replacing `/path/to/Nulleinspeisung.py` with the actual script path:
|
|
```bash
|
|
docker run -d --name nulleinspeisung-container -v /path/to/Nulleinspeisung.py:/app/Nulleinspeisung.py denshooter/nulleinspeisung
|
|
```
|
|
|
|
## Building the Docker Image
|
|
For those who prefer to build the Docker image themselves, the Dockerfile is provided in the repository. You can build the image by running the following command in the directory containing the Dockerfile:
|
|
```
|
|
docker build -t nulleinspeisung .
|
|
```
|
|
|
|
### Updating the Script and Restarting the Container
|
|
To update `Nulleinspeisung.py` and restart (if build container yourself remove the 'denshooter/' part:
|
|
```bash
|
|
docker stop nulleinspeisung-container
|
|
docker rm nulleinspeisung-container
|
|
docker run -d --name nulleinspeisung-container -v /path/to/Nulleinspeisung.py:/app/Nulleinspeisung.py denshooter/nulleinspeisung
|
|
```
|
|
|
|
### Additional Notes
|
