Sense had worked with my small Philips Hue setup through early this morning. Suddenly this evening all of the Hue lights are showing as off even though they are on.
As an aside, Sense says there are 6 lights connected via Hue. In actuality there are only 5. I have confirmed that in the Hue App as well, as seen below. See the phantom Hue Color Lamp 1 in the Sense Device list.
