There is currently a vast amount of sensors, actuators, and other devices intended to create the Internet-of-Things. However, most of these only operate within a particular manufacturer’s ecosystem and with a limited set of compatible hardware. In response to this we present a general sensor and actuator gateway for the Internet-of-Things, which provides the flexibility to easily exchange sensor and actuator hardware. The gateway is implemented as a proof-of-concept prototype that is verified to be compatible with a wide range of commercial off the shelf hardware. It is also shown to be able to run the SensibleThings platform, a fully distributed and open communication platform for Internet-Things applications.
