Massively deployed wireless sensor and actuator networks (WSAN), co-existing with RFID technology, can bring clear benefits to large-scale enterprise systems, by delegating parts of the business functionality closer to the point of action. However, a major impediment in the integration process is represented by the variety of customized WSAN platforms and proprietary technologies. In this paper, we present a three-layer service-oriented architecture that accommodates different sensor platforms and exposes their functionality in a uniform way to the business application. Our work is motivated by real business cases from the oil\&gas industry. In our implementation, we use three sensor platforms (Particle, $\mu$Node and Sindrion) integrated through the UPnP standard and incorporated into SAP enterprise software. The practical tests and application trials confirm the feasibility of our solution, but also reveal a number of challenges to be taken into account when deploying WSAN on industrial sites.
