Raspi Controller is a Raspberry Pi-based IoT project designed for home automation with botanix(Bitcoin Blockchain) integration. The project allows users to control home devices securely and efficiently using blockchain technology, ensuring trust, security, and authentication among IoT devices.
Raspi Controller leverages the power of Raspberry Pi's GPIO pins to control home devices while integrating blockchain technology for enhanced security and trust among connected devices. The project includes a smart contract system that stores and updates pin statuses with access control by the owner. When authorized users update pin statuses, the contract emits events with the respective pin number and status. A Python listener then detects these events and updates the Raspberry Pi pins accordingly, simulating device control in a secure and decentralized manner.
- Node.js 18+
- Python 3+
- Windows 8+ (for simulating GPIO pins)
- Windows Build Tools - Only for Windows (Simulating GPIO pins on Windows)
- Raspberry Pi (for actual GPIO pins)
- Some Botanix Testnet BTC (for deploying contract and interacting with the client) - https://faucet.botanixlabs.dev/
This project consists of three main components:
Copy
.env.exampleto.envand fill in the required environment variables.
- Install required dependencies
npm install- Compile the contract
npx hardhat compile- Set Private Key to hardhat config variables (For deploying contract to network. Make sure you dont use your primary account)
npx hardhat vars set PRIVATE_KEY- Deploy the contract
npx hardhat run scripts/deploy.ts --network <network>Copy
client/.env.exampletoclient/.envand fill in the deployed contract address and other required environment variables.
- Install required dependencies
cd client
npm install- Start the client
npm run dev-
Navigate to
http://localhost:3000in your browser to see the client. Connect your wallet and start using the app. -
Register Device with the contract by clicking the "+ Device" button in the client interface.
-
Load the control panel with registered device Id by entering device Id and click on arrow button.
Copy
.env.exampleto.envand fill in the contract address and RPC URL.
- Install required dependencies
pip install -r requirements.txt- Run the event listener
python listener.py- Enter the registered device Id in previous step when prompted.
-
Connect your wallet to the client interface and register a device with the contract.
-
Load the control panel with registered device Id by entering device Id and click on arrow icon.
-
Start the event listener in new terminal and enter the registered device Id when prompted.
-
Use the client interface to turn pins on or off.
-
The event listener will listen for choosen device events in the contract and simulate/update the GPIO pins on the Raspberry Pi.
