# GREE Controller — Home Assistant distribution

This directory contains the OCI build, Home Assistant add-on repository source, custom integration and repository synchronization tooling.

## Configuration

Create the local build/repository configuration once:

```bash
cd ha-addon
cp .env.example .env
$EDITOR .env
```

`build.sh` and `sync-repository.sh` read all deployment-specific values from `.env`; `.env` is ignored by Git.

Important variables:

```dotenv
REGISTRY=repo.example.com
IMAGE_NAME=gree-controller
DISTRO=alpine
RUST_VERSION=1.89
BUILD_PLATFORMS=linux/amd64,linux/arm64
BUILDER=gree-controller-multiarch
BUILDER_CONFIG=
HA_REPO_URL=https://repo.example.com/gree-controller-ha-addon/
HA_REPO_BRANCH=master
HA_REPO_PATH=../gree-controller-ha-addon
ADDON_DIR=gree-controller
INTEGRATION_DOMAIN=gree_controller
```

## OCI image

```bash
./build.sh render
./build.sh load amd64
./build.sh load aarch64
./build.sh push
```

The project version comes only from root `Cargo.toml`. `render` synchronizes it to `Cargo.lock`, add-on `config.yaml` and the custom integration `manifest.json`, and sets the OCI image from `.env`.

## Home Assistant repository

```bash
./sync-repository.sh
```

The command updates/clones `HA_REPO_URL`, mirrors the repository and pushes only when content changed. The resulting repository contains:

```text
repository.yaml
gree-controller/                    # Home Assistant add-on
custom_components/gree_controller/  # Home Assistant custom integration
```

The custom integration source is maintained only in:

```text
ha-addon/home-assistant/custom_components/gree_controller/
```

It is added to the separate HA repository during synchronization, so it is not duplicated in this project.

Adding the repository to the Home Assistant add-on store installs the add-on only. The bundled custom integration can be copied from the same repository to `/config/custom_components/gree_controller/` when required.
