A:AnswerI recently bought Sonos - One Wireless Speaker with Amazon Alexa Voice Assistant for the same reason your aiming for. It was dissapointing to find out that you CAN NOT SYNC with the rest of the Echo family, It does not make sense to have Alexa build in such a good speaker to not have this. Hope that answers your question.

A:AnswerSure. Use it outside. I wouldn't put it in direct sun, my choice. Alexa will find you as long as you are connected to Wi-fi and have downloaded the app.
