VOCOlinc Flowerbud Smart Diffuser

A unique smart essential oil diffuser that integrates directly with Apple HomeKit via Bluetooth (requires a HomeKit hub). It allows for scheduling, remote activation, and integration into scenes and automations-like turning on with a 'Good Morning' scene. It features adjustable mist modes, color-changing LED mood lighting, and a large water tank. While its HomeKit functionality is a standout niche feature, the Bluetooth connection can be less responsive than Wi-Fi or Thread devices.

It's also primarily a diffuser first; the smart features are a bonus rather than a precision tool.
