Great product and great concept - works well with siri and google home... when the light switch is left on, if someone turns the lights off manually, the power is cut to the bulb.
Philips need to develop some sort of wall switch for these that can replace existing physical hardwired switches, allowing the switch to trigger an on/off without cutting power to the bulb.
Colour range is excellent and the brightness is good - very easy to install and pair new bulbs to the bridge
The app works well, but I wish you could bridge scenes to multiple rooms simultaneously, for example, I have an open plan kitchen dining & living room, with 4 separate 'rooms' in the app - i would like to be able to bridge these to one zone so I can set colours etc across the whole area, but still turn off individual area's as required.
