First of all, the HomePod is not waterproof. This means no rain, no splashing water on the HomePod from a pool, no sprinklers or snow, etc. The hot sun is probably not an ideal environment for the HomePod, either.
No room mapping data is sent to Apple. HomePod can automatically customize its sound based on the interior of the room. Moving the HomePod means it will scan the area and map sound to the new space.
Apple makes the HomePod in White and Space Gray.
The HomePod features a profile under 7 inches in height. The exterior is covered in a cloth speaker grille, which matches the other parts of the device.
The top of the HomePod includes a display for Siri and volume controls. All components of the HomePod, including the power cable match the White or Space Gray exterior.
The official Apple Support YouTube channel has added several tutorial videos about HomePod. Each video is around a minute long, highlighting different features of Apple's smart speaker. New users and HomePod experts alike will find helpful tips along with links to related support documentation.
Sometimes you may want a little privacy even from your smart devices. Whatever the reason, you can deactivate the "Hey Siri" voice command on your HomePod so it's not always listening.
To disable the "Hey Siri" option on your HomePod navigate to the settings in the Home app on your iOS device, then tap the "Hey Siri" toggle so it is OFF. You can also simply just say "Hey Siri, disable Hey Siri." The HomePod will then ask you to confirm with a "yes" to disable the voice command feature.
