In this tutorial, we’ll use Akka to build out part of an Internet of Things (IoT) system that reports data from sensor devices installed in customers’ homes. The example focuses on temperature readings. The target use case simply allows customers to log in and view the last reported temperature from different areas of their homes. You can imagine that such sensors could also collect relative humidity or other interesting data and an application would likely support reading and changing device configuration, maybe even alerting home owners when sensor state falls outside of a particular range.
