That actually makes sense. In fact I would even consider it because they only have multiple syllable trigger words for Alexa (3 in the default) and that's a struggle for one of our users. If I could replace it with "Hey!" and change "Alexa, turn lights on" to "Hey light on" that would be great. I may have to get my soldering iron out now.... If only I had a friend with a new 3D printer.... oh...
