HomePod activating on its own randomly
My home Pod is activating at random time, sometimes in the middle of the night, playing music at maximum volume. I have a pair of Home Pods, and one is fine the other is the crazy one. When I stop the music, it waits for a few minutes and restarts playing the music. I've talked with 7 senior support specialists and they all seem baffled. One intimated that engineering has encountered this problem. We've tried everything, including plugging it into my Mac and restoring the software.
Can I assume that the speaker is foobar? Are they repairable, or would it be cheaper to just buy a new one?
