I just set up a pair of these bulbs with my new Echo Plus (no separate bridge) and I have full control of these bulbs (on, off, dim etc.). I set them up in two living room lamps as "Living Room Light 1" and "Living Room Light 2". I then set up a group called "Living Room Lights" and put both lights in the group. All of the set up was done directly in the Alexa App on my iPhone. Now I can control each light individually ("Alexa, turn on Living Room Light 1") or as a group ("Alexa, dim the Living Room Lights to 50%") in which case both will respond at the same time. I have found the ability to dim seems to work from 12% to 100% which is fine for my needs (as well as on & off). Everything works exactly as expected and the set up was very easy.
