Honestly, I’ve been less impressed with Ubi lately. For a while it was working pretty well for me, but I think they did an update a while back and it’s been a bit more spotty since then.
On the good side, it’s less likely to false trigger, especially from the TV.
On the bad side, it’s less likely to understand me, seems to be a little harder to get a true trigger, and HTTP sends to Ubi can be slow/late. (For example, I have Ubi make an announcement when my car gets home. ST also home my garage door at the same time. Yesterday when I got home, my door opened. I parked my car, got out, when in the house, dropped my bag in the living room, and only THEN did Ubi announce that I was home.)
