I purchased the light and took a little bit to reverse engineer what pins did what but in the end it was one of the easier devices to hack. The main reason is all the IO is controlled by the main ESP. They do not have a secondary microcontroller that needs to be interfaced with. The main center light and the RGB ring are controlled independently.
