Expression, Event, Alarm

The modern building is alive with activities. Not just human activities, but activities of the systems that exists within, and those that interacts with it from the outside. These activities are mostly unseen and untapped – we typically only make use of a fraction of the data being generated.

Building data can be ingested by Senfi to facilitate automation and improve building operations. To do so, Senfi provides an event-driven autonomous workflow engine. Similar to other event-driven architectures, users may define events in Senfi and specify actions to be carried out when an event occurs. Senfi provides a flexible way to define the conditions for triggering events in the form of an expression. Events may also optionally raise alarms, if it is intended to be handled by a human operator.
