I understand you purchased a Logitech Circle 2 Indoor/Outdoor Weatherproof Wired Security Camera and would like to know how to set it up with Apple HomeKit. The resources below will provide some general guidance for using accessories with Apple HomeKit. You may need to reach out to Logitech directly regarding how to use the Logi app. See the links below for more information.
