About Yale Access
Yale’s smart-lock systems all come from the same place: the cloud platform originally built by August. In North America this platform is used through the August and Yale Access apps, while everywhere else it appears as the Yale Home app — but the underlying technology is essentially the same. The only “real” API behind these products is the August Developer API, which is the official gateway to that shared cloud (though it is restricted and mostly US/Canada–only). Confusion comes from the naming: Yale Access (US/CA), Yale Home (rest of world), and Yale Connect (the Wi-Fi bridge hardware or, in some regions, a separate older Yale ecosystem). Some locks only work with one ecosystem, while others can switch by using different modules, but in most modern cases the smart features are powered by the August/Yale cloud, just presented under different brand names depending on the region.
