In this paper we introduce the  Spatio Temporal Filtering Language (STFL) , which is a language framework that aims to provide the primitives for easily defining rules and sequences of rules and constraints. These sequences of rules can be used to convert low-level streams of sensor data into higher-level semantics and provide triggers for actuation. Among others  STFL  provides support for heterogeneous types of sensors, composability and code reusability. Special emphasis is given on the support of different categories of users by providing different types of interfaces spanning from a natural-like language aiming at end-users to a regular scripting language aiming at system developers. The expressiveness and power of  STFL  is presented through an assisted living scenario.
