Device synchronization and testing
The present invention provides a platform that enables devices, services and applications to be connected together. Creating a “connected environment” via this platform requires co-ordinating multiple device manufacturers and service providers, and multiple standards/protocols. Advantageously, the platform removes the requirement for different manufacturers of different devices to adopt common protocols to enable device connection, and further, the platform removes the burden of configuration away from the consumer. Time-dependent behaviors, and time-dependent behaviors of groups of devices, may be tested in a simulated environment to identify emergent behaviors and software bugs before they are implemented via the platform, to enhance the user experience.
