What does it take to win the Open IoT Challenge 4.0?

The Open IoT Challenge (https://iot.eclipse.org/open-iot-challenge/) is an annual challenge to promote the use of open source and open standards in IoT solutions. The winners of the fourth Challenge were recently announced (https://www.eclipse.org/org/press-release/20180404_iotchallenge_winners2018.php) and they will be joining us to present their solutions.

Winning solutions are:

1st place: Activ-IoTy
Activ-IoTy Timekeeping is a modular low-cost solution for timekeeping and athletics competition management. It is based on standard technologies such as RFID, JSON-LD, and MQTT that enable to easily acquire, publish, and share information related to athletics events. Using Eclipse Mosquitto, Eclipse Paho, and many other open source projects, the Activ-IoTy team has built a fully functional IoT solution and the judging panel was particularly impressed by the thorough testing efforts of the team in real-life environments.

2nd place: Trusting IoT
Trusting IoT provides a trusted indoor positioning system for nursing homes that can be used to guarantee appropriate care of the elderly. The solution uses Eclipse Kura and Bluetooth low-energy beacons to implement the indoor positioning system. The IOTA distributed ledger is used as a way to store a permanent and unalterable history of the positions of the residents at any point in time.

3rd place: Smart Solar Water Heating
Smart Solar Water Heating uses IoT and AI technologies to improve the efficiency of passive solar water heating systems. This project leverages open standards such as OMA LWM2M MQTT, several open source projects (including Eclipse Wakaama, Eclipse Leshan, Eclipse Kura) for telemetry and control, as well as other open source projects (including Enmasse and Apache Spark deployed using the OpenShift Origin platform) to enable device connectivity and to help predict the availability of hot water.
