- Being disappointed by how our apartment handles paying the electricity bills.
What it does
- Cryptility allows for the instantaneous and decentralized micro-transactions to pay for utilities.
- A device senses the power being used by an outlet, and immediately pays for the power from a locally hosted Xpring wallet.
- A dashboard allows individual users to view metrics about their consumption habits.
How we built it
- Crytpo-enable IoT device communicates over serial to an Arduino that reads sensors and controls power to devices.
- Writes to DynamoDB, triggering event-driven Lambdas with application logic.
- ReactJS frontend displays diagnostics active monitoring of utilities.
Challenges we ran into
- Dragonboard 410c came with Android installed, and had to install Debian manually.
- The IoT device had to be highly asynchronous, handling both https requests to different endpoints and communication over USB serial.
- None of us had worked extensively with AWS prior to this Hackathon.
- Updating the balance of a crypto wallet on the portal
Accomplishments that we're proud of
- Built an cryptocurrency enabled IoT outlet that reports power usage.
- Getting many compatible parts work together (Express server, Arduino, DynamoDB, S3, Lambda, Xpring).
What we learned
- Embedded operating systems are often difficult to install
- A majority of the time spend working with AWS is used for configuration.
What's next for Cryptility
- Interledger compatibility, allowing for users and providers to pay in their currency of choice.
- Options to allow users that produce energy (i.e. from solar panels) to get paid in real time.
- Admin portal and automation that allows for energy produces to dynamically set rates.
