Yesterday we noted that Apple launched a new Find My Certification Asst. app, designed to test support for third-party hardware. Find My, of course, has been a long-standing feature for Apple’s own hardware like iPhones, AirPods and Macs, but back at WWDC, the company announced plans to open it up to manufacturers.

Today the company made official its Find My Network Accessory program and unveiled a handful of hardware that will take advantage of the new Made for iPhone (MFi)-affiliated offering. Users will be able to locate missing devices via Apple’s Find My app.
