Running 3 Hue bridges/hubs here, and have done systems with many more than that. As others have mentioned, set them to a static IP (I set mine sequentially .200, .201, .202 etc) so I’d know where they were in the IP scheme. Also, Composer always defaults to any new bulb driver being connected to the first bridge that’s setup, so for bulbs on a different bridge, you have to manually bind them (Composer Pro required). Other than that, pretty much rock solid functionality with 100+ bulbs, led strips running for a few years now, with one bridge per floor. Sent from my iPhone using Tapatalk
