Thanks @cjkeenan, I would never have looked at the Alexa option, I'll give it a go and see if it does what I need.
One example use case is I want to be able to walk into a room, have the motion lighting setup through the app turn the lights on, but then press a Hue dimmer button or have a switch turn on cause the lighting rule to essentially stop, leaving the lights on until I turn the lights off with the Hue dimmer or some other situation. This all worked perfectly for me up to the last point. I could pause the rule so the lights would remain switched on when I pressed the Hue dimmer button, but when I turned the lights off with the Hue dimmer, when I later re-entered the room, the motion lighting rule would log that it would not turn the lights on because they were already on.
