Also, Sidewalk helps devices like water sprinklers and pet locators work over longer distances. Sidewalk uses a small portion of your internet bandwidth to provide these benefits to you and your neighbors via Sidewalk Bridges (participating Echo and Ring devices), and is turned on for your device unless you have previously turned off the setting. You can turn off Sidewalk at any time. Learn more about Sidewalk.
