## Configuring and usage


### Docker

Todo


### Bare-bone

The script can be configured using the .env file where you can adjust it (hopefully perfect) to your needs. After that, just run the script:

```bash
python3 lge320reader.py
```

Please note: the .env file needs to be in the same folder or any other folder higher up in the directory structure as the script (more specifically, the WORKDIR). It is just a help, actually, the script searches for specific variables in its environment variables. It only loads the .env file so that you do not need to `export` all the files before running (see https://pypi.org/project/python-dotenv/ for more details). This also means that when using it in docker, you can set the docker containers environment file to that .env file and it will be accepted too.


## Building docker

To build the image for docker, simply use the following commands:

```bash
docker login  # login to docker hub
docker buildx create --name buildx-multi-arch
docker buildx use buildx-multi-arch
docker buildx build --no-cache --platform linux/amd64,linux/386,linux/arm/v5,linux/arm/v7,linux/arm64/v8,linux/ppc64le,linux/s390x -t bluefox42/solarcontrol:<VERSION> -t bluefox42/solarcontrol:latest . --push
```
