Abstract

Systems and methods are described for configuring a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinated devices may include devices configured to be managed remotely, such as thin devices, devices with alternative primary functions (e.g., appliances, household objects, etc.), or devices with limited localized user interfaces. To manage the set of coordinated devices, the coordinator can execute tasks, each task corresponding to a set of portable code executable by the coordinator to implement a desired functionality. A user may generate one or more tasks, and submit them to a service provider environment for deployment to the coordinator. The service provider environment can utilize a device shadow to notify the coordinator of the obtained tasks, and thereafter deliver the tasks to the coordinator, thus modifying a configuration of the coordinator.
