At Google I/O 2019, the host company announced plans to release the Local Home SDKTrack this Framework/Library. This new solution, which was recently launched as a developer preview, aims to reduce latency and improve reliability by allowing smart home device providers to run actions locally rather than in the cloud.
This solution also has potential security benefits. By processing requests locally, more user information is able to stay on-device, potentially removing the risk of cloud breaches of data. This is important since as we discussed yesterday on ProgrammableWeb, smart home security is a complicated issue that deserves the respect of device manufacturers, IoT platform providers (like Google), and end-users.
