Integrate Everything with IOTA Hackathon Winners Announcement
4 min readDec 7, 2020


The Integrate, Everything with IOTA Hackathon was an initiative headed by IOT2TANGLE and supported by Bosch Connectivity, STMicroelectronics, Espressif, Senseering, VASS Company, Ruuvi, IOT ONE Academy, and the IOTA Foundation. This contest had as its main mission to call for IoT/IOTA open-source codebase integrations of value that showcase how the data produced by different devices could be distributed through the Tangle and offered with a PubSub logic.

From 26 projects that signed-up, 18 worked hard for one month and submitted their integrations for the Jury to evaluate.

Before we list the winners, we must say that all of the 18 projects delivered were outstanding: great and creative concepts, properly documented to allow further development on behalf of the open-source community. We are proud and confident that we will hear about these projects in the future.

You can find the list of all the 18 projects in the Hackathon website.

Selecting only 5 winners was a challenging endeavor for our Jury, composed by Daniel Trauth (Senseering), Holger Koether (IOTA Foundation), and Samuel Beriguete Valero (VASS Company).

After talking with our sponsors, we decided to add 3 more projects to the podium as Honorary Mentions. Each of these projects will receive a Custom IF Ledger Nano, a Espressif ESP32-S2-Kaluga-1, an IOT ONE Academy IOTA Developer Course and $250 USD in IOTA.

Let us meet the winners!

The 5 winners

The five winners will receive the prizes listed on the Hackathon website.

First prize: IIoT Through Tangle (IIoT)

Enables connection of a Mitsubishi PLC with the Tangle using a Raspberry as a Gateway and a Mitsubishi GT2505 Display. It Measures the OEE (Overall Equipment Effectiveness) performance of a machine simulated with Factory I/O.
Contestant: Eliabel Barreto (Brazil)

Second Prize: Argos Delivery (Supply Chain Tracking)

Argos Delivery lets you track a package across the entire delivery process from end to end. If the package is dropped, a sensor device inside sends a message to the “digital twin” of the delivery on the IOTA Tangle. This data can later be used to detect weaknesses in the supply chain or to settle insurance issues.

Third Prize: IOTA Distributed Ledger Technology Brings Trust to Public Drinking Water (Water Monitoring)

Running Node-Red on an IoT edge gateway (Raspberry Pi) between a Endress+Hauser Industrial Water Analyzer and the IOTA Tangle.
Contestant: Gerhard Greeve (United States)

Fourth Prize: IOTA Workshop (Granular Economy)

IOTA Workshop bridges the Tangle from the digital sphere to the material world by enabling physical tools as a service. A proof of concept showing that IOTA can be used to autonomously rent tools, the instruments of labor.
Contestant: William Wyatt (United States)

Fifth Prize: RoS2Tangle (IIoT)

Enables industrial robots to send data to the Tangle. The requirement that these Robots must have is to be compatible with the OpenSource Robot Operating System called ROS.

Honorary mentions

Given that a top 5 left too many outstanding projects without an award, the Jury decided to add three honorary mentions to the top 5.

Sixth: IoTraffic (Smart Traffic)

Utilizes AI to recognize cars from camera (ESP32Cam) images and stores the data on the Tangle. Regulates traffic lights timing according to the number of cars. Perform actions such as call an ambulance if it detects accidents. Detects car's speed and can post a photo of the car together with its speed on the Tangle.
Contestant: Raul Antonio Rosa Padilla (Italy)

It provides a connectivity method between the IOTA Protocol (Streams) and OPC UA protocol to receive sensor data via OPC and forward it to Streams using the I2T Gateway.
Contestant: Hauke Jung (Germany)

Eighth: Rainwater-Buffer (Smart Cities)

Rain barrels system connected to roof drain pipes that measure water level using an ultrasonic sensor and activate a valve to release water on certain levels to avoid flooding from coming rains.

Hackathon takeaway

This has been an extremely positive experience! Being able to walk together with most of the contestants while trying to connect their IoT projects with our open-source solutions allowed us to learn many things about our work. Indeed, IOT2TANGLE will grow stronger from this amazing experience.

As for all the projects, winners or not, we know for sure that the world will hear about them in the future. These guys have done an incredible job that proves how IoT devices can use the IOTA protocol from many verticals.

In the coming weeks, we will be sharing some of the amazing projects that did not make it to the TOP 5 +3 with the community. Once you see all this work, you will understand how tough it was for the Jury to only select 5 integrations.

Congratulations to all of you, and thanks for sharing your ideas
This is just starting!
