Abstract: Traditional home-automation systems utilize a single hub for controlling secondary devices within a home. The techniques described herein, meanwhile, utilize multiple hubs within the environment and/or located remotely from the environment. For instance, an environment may include multiple electronic devices, each configured to control one or more secondary devices within the environment. In addition, a remote service may be configured to control one or more secondary devices within the environment. As such, each controlling device stores and executes an instance of a control engine, rather than relying on a single instance of a control engine located at a single controlling hub.
