I have two Philips Hue Bridge drivers (due to having more devices than one bridge can support), and have this afternoon, replaced the older Hue light drivers, with the new Philips Hue Light (OS 3.3.0+) drivers.
For all of the lights on Bridge 1, all is well.
However, I have one light on Bridge 2, but it doesn't appear in the drop down list of available lights, even after pressing Actions>Update Available Lights.
So, it looks like the new Philips Hue Light driver only supports one bridge connection at present.
Hopefully this will get fixed, as the previous drivers worked fine with more than one bridge.
So for the present, I'm keeping the Bridge 2 light on the old 'Single Lamp White Warmth - FREE' driver
