Are we still talking about that crappy little hype project that just polls the ring data from their API? That doesn't avoid the subscription at all to get the data in there to begin with. That's just using the ring as originally designed. No, we want an offline solution directly from the ring. It doesn't seem like anyone has managed to get around needing it to call home at least once to initialize. That still requires an app install and a subscription to get started. Nobody is buying these secondhand for cheap and then truly and completely bypassing the official app. This project is the closest I've found to doing it properly, but you still need to extract the key after initialization before ditching the official app and subscription. https://github.com/Th0rgal/open_oura
