The Echo can do everything on that list. The pebble is the only thing I don't know about. But with smartthings, and Ifttt. Only downside is getting The Echo to give feedback but there is a way to do it through smartthings and a tablet or phone using bluetooth.
I'm slowly shifting completely to my Echo's as I only use the Ubi's for announcements but shifting them over now since there is a way to have Echo do them now. And now knowing hardware support for Ubi is dead means I can't rely on it for the long term. The harmony and smartthings integration is amazing.
