Apple's rumored smart home device with a mounted iPad-like display for smart home controls has been delayed until 2026.The delay is due to major engineering hiccups with the overhauled Siri voice assistant, which plays a central role in the device.The device is still in development, with limited testing by Apple employees in real-world scenarios.It is unclear if Apple will offer a preview of the product at WWDC 2025 in June.
