🚀 What's New in v1.2.0

Home Assistant 2026 Compliance

1. Runtime Data Pattern

# OLD (v1.0, v1.1) - Deprecated
hass.data[DOMAIN][entry.entry_id] = coordinator
coordinator = hass.data[DOMAIN][entry.entry_id]

# NEW (v1.2) - HA 2026 Standard
entry.runtime_data = coordinator
coordinator = entry.runtime_data

2. Type Aliases (Python 3.12+)

type WTHConfigEntry = ConfigEntry[WTHCoordinator]

async def async_setup_entry(
    hass: HomeAssistant, 
    entry: WTHConfigEntry  # Typed!
) -> bool:

3. Direct Device Registration

# Registers device in device registry immediately
device_registry = dr.async_get(hass)
device_registry.async_get_or_create(
    config_entry_id=entry.entry_id,
    identifiers={(DOMAIN, entry.entry_id)},
    manufacturer="WTH",
    model="UMR2",
    # ... all device info
)

4. Coordinator Shutdown

async def async_shutdown(self) -> None:
    """Proper cleanup on unload."""
    await super().async_shutdown()

5. Performance Optimization

super().__init__(
    hass,
    _LOGGER,
    name=f"{DOMAIN}_{entry.entry_id}",
    update_interval=SCAN_INTERVAL,
    always_update=False,  # Skip unnecessary updates
)
