The video does not really show the setup and configuration of the UI, I have no idea what kind of UI it is and where it sits VS Openhabs UI options.
I am after true automation where I don’t have to find my phone, unlock it, navigate and then start X event. Sensors should trigger the event to happen without me needing to do anything and if that is done then I don’t care too much what a testing interface looks like. Just my opinion and yes I would love to see Openhabs UI’s move forward which I believe is what Openhab 3 is going to make a reality.
Openhab has a very consistant look and feel that is the same across iOS, Android and generic web browsers. Don’t under estimate the need to keep any UI’s consistent across all platforms and from one update of Openhab to the next. Yes my UI has not changed in 10 years but that helps with the WAF as there are no breaking changes each time I do an update.
I posted about an idea I had here a while back.
