Disclosed are various examples for dynamically generating and implementing scenario profiles for a network of devices, including IoT devices. A managed device can receive a dynamically generated scenario profile that defines tasks to be performed by the device for a given scenario. The device can also receive a scenario message that is broadcasted to all managed devices in a network and identifies an occurrence of a given scenario. If the device determines that the device is an intended recipient of the scenario message, the device can identify the scenario profile associated with the given scenario and perform the tasks defined by the scenario profile. The scenario profile can be modified and/or updated based on event data associated with the device.
