[BOUNTY: 10,000 WATT] Raspberry Pi sensor oracle

[WattCoin-Org]

Description

Build a Pi application that reports real-world sensor data (temperature, humidity, motion, etc.) as verifiable data for the WattCoin network.

Requirements

• Reads from common sensors:
  • DHT22 (temp/humidity)
  • PIR (motion)
  • Or similar GPIO/I2C sensors
• Reports to a configurable API endpoint (default: /api/v1/oracle/report) with:
  • Sensor type
  • Reading value
  • Timestamp
  • Signed by wallet
• Local logging and history
• Configurable reporting interval
• Mock sensor mode for testing without hardware
• No shell=True in subprocess calls (use shlex.split())

Acceptance Criteria

• At least 2 sensor types supported (real or mock)
• Signed reports to API
• Local history viewable
• Install script for Pi
• Wiring diagrams included (for real hardware)
• Tests included and passing

Bounty

10,000 WATT

Notes

• The backend API endpoint is not yet built — your script should work against any configurable URL and gracefully handle connection errors.
• Include your personal Solana wallet in the PR body (not the project wallet). Format: **Payout Wallet**: <your_address>

Implemented a minimal sensor-oracle scaffold in PR #220: https://github.com/WattCoin-Org/wattcoin/pull/220\n\nIncludes two sensor types (DHT22 temp/humidity + PIR motion), signed submission flow, local history logging, Pi install/service scripts, and wiring docs.

补充：PR #220 中的上报接口是 /api/v1/oracle/report（签名+本地history）。

Hi team, I read through #19 and I can own this.

• My read: this is primarily a UI/UX task tied to "[BOUNTY: 10,000 WATT] Raspberry Pi sensor oracle".
• I will focus on these issue-specific points first: bounty, watt, raspberry.
• First I will reproduce and confirm expected behavior for the UI/UX path.
• Then I will implement the fix with targeted tests and keep scope tight (good confidence).
• I will share a working PR update fast (24h for first patch, 48h for final polish) with verification notes.
  If this approach works for you, I can start now.
