## Local Development

### Backend

```bash
cd core/backend
python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate
pip install -r requirements.txt
python -m alembic upgrade head
uvicorn app.main:app --port 8000 --reload
```

### Frontend

cd frontend
npm install
npm run dev
# Opens at http://localhost:3000, proxies /api to localhost:8000
```

---

## Sungrow API Configuration

Fill in Sungrow iSolarCloud API credentials in `.env`, then set `USE_SIMULATOR=false` to connect to real data.

---

## Updating Core

When ems-core releases a new version:

```bash
git subtree pull --prefix=core ems-core main --squash
```

Make sure the `ems-core` remote is configured:

```bash
git remote add ems-core http://100.69.143.96:3300/tianpu/ems-core.git
```

After pulling, update `core_version` in `VERSIONS.json`.

---

## Version Management

### Releasing a New Version

```bash
# 1. Update VERSIONS.json (project_version, last_updated, notes)
# 2. Commit
git add VERSIONS.json
git commit -m "chore: bump version to vX.Y.Z"

# 3. Tag (MUST be after VERSIONS.json update)
git tag -a vX.Y.Z -m "vX.Y.Z: release description"

# 4. Push commit + tag
git push origin main
git push origin vX.Y.Z

# 5. Update Gitea description (Settings page or API)
```

Version must match in all three places: `VERSIONS.json`, git tag, and Gitea description.

### Download / Switch to an Older Version

```bash
# List all versions
git tag -l

# Switch to a specific version
git checkout v1.1.0

# Compare versions
git diff v1.1.0 v1.2.0

# Download as zip (no clone needed)
curl -o zpark-ems-v1.1.0.zip \
  "http://100.69.143.96:3300/tianpu/zpark-ems/archive/v1.1.0.zip"

# Go back to latest
git checkout main
```
