  Modern technologies such as the Internet of Things (IoT) are becoming
increasingly important in various domains, including Business Process
Management (BPM) research. One main research area in BPM is process mining,
which can be used to analyze event logs, e.g., for checking the conformance of
running processes. However, there are only a few IoT-based event logs available
for research purposes. Some of them are artificially generated and the problem
occurs that they do not always completely reflect the actual physical
properties of smart environments. In this paper, we present an IoT-enriched XES
event log that is generated by a physical smart factory. For this purpose, we
create the SensorStream XES extension for representing IoT-data in event logs.
Finally, we present some preliminary analysis and properties of the log.
