I am no expert, but I believe when paired to a Hue Bridge, these bulbs use ZLL and properly route/repeat ZLL commands. When paired directly to Hubitat, they have to use ZHA, and thus they are asked to route/repeat for non-lighting devices like motion, temperature, water, switches and dimmers, door/window, etc... That is where they don't too well.
If someone knows differently, please correct me as I'd hate to spread misinformation.
