Afaik Homey pro had multiple IR leds all around at the outside instead of one really bright one deep in the middle. I wouldn’t dare to guess the difference based on the keynote.
Seeing the disc design I would dare to guess a led in the middle means a narrow horizontal plane and no direct IR light above or below. That will work well at similar hights but will rely on reflection of walls for anything outside that plane.
But I also do not think the Homey PRO IR problems were related to IR led strength but to software implementations and lack of proper IR learning. So if that doesn’t change, the IR led strength is moot unless there’s an app from the device manufacturer that knows how to properly send the right codes.
