  • Publication number: 20200125050
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for initiating actions based on sequences of events. In one aspect, a process includes receiving, from each of multiple devices, data specifying an event detected by the device. The events are compared to configured scenarios that each specify a sequence of trigger events and an action to be initiated in response to detecting the sequence of trigger events. A determination is made that the events match a first scenario of the scenarios. In response to determining that the events detected by the multiple devices match the first scenario, a first action specified by the first scenario is initiated. A determination is made that a combination of one or more of the events detected by the multiple devices and the first action matches a second scenario. In response, a second action specified by the second scenario is initiated.
