A:AnswerI have a Hues Bridge, Apple products with home app, and Alexa. I put in the bulb, named it in the Hue App. It automatically worked in Apple Home and with Alexa.
A:AnswerNot even shades of white. Just one color of white that you can dim. They have color change and those have many shades of white but these do not.
A:AnswerEach bulb will answer to a different command. You can set up a routine with Alexa that would include all 3 lights and then you tell Alexa the command like "give me light" or whatever phrase you want to think up. You would need 1 phrase to turn on and 1 to turn off. Once you set up a routine it is really very easy to do.
