A:AnswerUnfortunately It does not. However the bridge does support a Large number of bulbs, so one bridge is a good investment if you pan on expanding or adding Hue Bulbs and other Hue items in the future.

A:AnswerYou won't need the remote any longer... You download and install the Harmony App and all the remote controls are now on your phone. I believe the Remote you have may actually work with it still... but Smart phone control and even VOICE control is available if you set it up with an Amazon Alexa ECHo Dot... another 50 bux but well worth it.

A:AnswerThat little jack is for adding the IR blaster to extend it inside a cabinet or outside a cabinet to complete the IR saturation of the equipment in the room, allowing you to actually conceal your equipment or the Hub base unit... It's not a headphone or sound jack. This unit only CONTROLS the AV systems with IR and WIFI abilities. It doesn't extend sound or audio outputs of anything.
