There is no "master" - we are all in control of our own destiny, and our flowtoys :)
Grouping is voluntary: You need to intentionally group your lights in order for them to be connected and synced. As of Nov 2019 firmware, the closed (white color) group requires coordinated grouping.

If you select one of the "open" groups (color groups in p5m1), all lights in that color open group are automatically connected, even if you didn't coordinate with them. However nothing can be saved or edited, and the group is lost after you turn off your lights. This is great for temporarily grouping with friends at a jam or festival, as you can all find each other easily, change the modes on each other lights, and do spontaneous shows and takeovers.
Some notes on grouping:
- You can have some of your lights grouped, and some not, or have a few different groups among your lights.
- Any light can temporarily join a group, but retain its old grouping data.
