From iOS 17, a new addition called Grid Forecast has been introduced to the Home app. Although it doesn't offer a new way to control accessories, it lays the foundation for potential smart home integration in the future. Grid Forecast provides insight into your local energy network through Apple's Home app. It divides your local grid production into two categories: Cleaner and Less Clean, allowing you to plan your home's energy use accordingly. Cleaner periods in Grid Forecast indicate that using more renewable sources can result in reduced CO2 emissions. On the other hand, using energy during less clean periods can increase your home's overall carbon impact. Additionally, cleaner periods may coincide with off-peak hours, potentially saving you money if you shift appliance use or electric vehicle charging to those times. Grid Forecast is available on iPhone, iPad, Mac, and Apple Watch and offers a timeline view, notifications, and a home screen widget. While it is currently only informational, it suggests that there may be future automation suggestions or automatic adjustments based on your local network forecast. To use Grid Forecast, you need to meet certain requirements. It is currently only available in the contiguous United States and requires iOS 17, iPadOS 17, watchOS 10, or macOS Sonoma. You also need location services for HomeKit and the Home app, as well as an active internet connection. You don't need to pair HomeKit accessories to view Grid Forecast. Enabling Grid Forecast is simple. If you already have an Apple HomeKit Home installed, it will be enabled by default after updating to iOS 17. If you don't see Grid Forecast, you can find the option in Home settings. To enable Grid Forecast notifications, you can set them up in the Home app. Additionally, you can customize your iPhone's home screen with the Grid Forecast Widget to keep track of your local grid forecast. The widget comes in two sizes and provides a timeline of the forecast. With Grid Forecast, you can easily stay informed about your smart home's energy consumption and achieve your energy-saving goals.
