I have already reported on the performance data of the Hue Bridge Pro, which is expected in September. The significantly more powerful bridge should be able to work with 150 lights and 50 accessories. The previous Hue Bridge was officially designed for 50 lights and 12 accessories, but slightly exceeding these numbers was not a problem until now.
