Sentilo is Barcelona's open-source IoT middleware, started by the city's Municipal Institute of Informatics (IMI) in 2012 and running in production since 2013. It ingests and openly publishes real-time data from municipal sensors — environment, noise, parking, irrigation, waste and water — as a vendor-neutral layer between devices and city applications. Released on GitHub under a dual EUPL 1.1 / LGPLv3 licence, it has been reused by other Catalan cities and administrations (Terrassa, Reus, Cellnex, the Catalan Water Agency) and won the 2016 Open Awards for open-source innovation.
