Also, I recommend a couple of things :
1) If you don't absolutely need to control each light, you don't need to put them all in the project. Use light groups instead. You can control a light group even if the individual lights are not all in the project. It is much more consistent when controlling multiple lights to do that than using light scenes, etc.
2) Turn off polling for the hub. It doesn't work correctly, and adds a lot of delay and lack of respsonsiveness.
3) Advanced Lighting Scenes don't always work correctly. But on/off for a light group or setting a light group to a % works very well generally.
4) If you do use lighting scenes, set tracking to "do not track". That way, if a light doesn't react correctly, you can hit the button again and it will resend the command to the bulb. If tracking is on, director will not think anything is wrong and ignore it.
I've got 300-350 hue lilghts across 9 hue hubs. Everything works 98% of the time if you do the above.
