SWETHER – Electrical switch wih Ethereum blockchain support

Blockchain based end-to-end prototype system comprised of IoT devices, decentralized applications (DAPPs) and user interfaces. Enables control of electric switch via Ethereum blockchain transactions. The user can reserve electric charging slot and pay for consumed time/energy via Ethereum network. It is a practical application of blockchain technologies in IoT devices.

Prototype system consists of: Smart contract: deployed in Ethereum network to execute dAPP logic; User and Admin Web applications: to be run in Ethereum compliant browsers like Mist or browser plugins; Swether: IoT device that intercepts events from Ethereum network and toggles its state accordingly. The solution enables several use case approaches models with customizable on- and off-chain elements.

Typical use cases

The developed technology is excellent for prototyping distinct IoT and blockhain solutions. The concept can be easily extended to e.g. charging of electric vehicles, arbitrary control of IoT devices, device-to-device transactions and interactions.
