Before You Reset Your HomePod
You should only reset your HomePod when absolutely necessary. As Apple states, you should reset your HomePod when you are sending the device in for service, are selling or giving the device away, or want to return the device to its factory settings.
Reset Your HomePod Using iPhone, iPad, or Mac
Just like initially setting up your HomePod with the Home app on your Apple device, you can reset it. So, open the Home app on your iPhone, iPad, or Mac and follow these steps. It may take several minutes for your HomePod to reset. When it finishes, you should hear a chime on the speaker.
Reset Your HomePod Using the Device
If you cannot reset your HomePod using the Home app, you can do so on the speaker itself.
Reset Your HomePod Mini Using Mac
If you have a HomePod mini, you also have the option to restore it to its factory settings using your Mac. This is because this smaller version of the original HomePod has a USB-C connector which can be plugged into your Mac. If restarting your HomePod doesn’t fix the issues or if you truly need to reset the device to its factory settings, it’s easy enough with HomePod or HomePod mini.
