there's definitely a hue skill i reinstalled it the other day but all the reviews from 2 days ago say it's stopped working.
i think they may have introduced a bug rolling out new hue security changes. one of the reviews mentions removing both hue and alexa apps and re-installing them to get it working.
Hue recently forced accounts for the Bridge, perhaps this has resulted in you needing to ensure you have a Hue Cloud account + a recent add-on to make it work?
