There was an article posted here recently about a device that feeds white noise to devices like that until you give the new device they keyword it's looking for. It was supposed to look like a fungus or something. Lemme see if I can find the article... Wouldn't help with location tracking, but might put your mind partially at ease if you own a creepy home assistant thing.
