Flic Hub PoE
If you iterate on the Hub, I would love to see the second generation able to take power from PoE. This would assist with corporate or advanced home deployments; less cables, no power outlet near Flic Hub required.

The circuitry to convert 48v 802.3af/at to 5v isn't exactly small or simple, but 12v passive shouldn't be too hard to implement.
