ESP32 Smart Plug Prototype Creation

Job Description: I am looking for an experienced electronics/embedded systems engineer to build a working prototype for a product called PlugSmart Saver. The goal is to create a renter-safe smart plug that: Core Features: Monitors real-time power usage (AC mains) Converts energy consumption to dollar cost Automatically shuts off power via a relay when idle or over limit Reads temperature for safety and shuts off in overheat situations Sends data to a Wi-Fi connected app/dashboard Deliverables: Fully working ESP32-based prototype on breadboard or PCB Schematics and wiring diagram Firmware that can: Read energy data from HLW8012/ATM90E26 or equivalent Control relay based on simple rules Report data over Wi-Fi Optional: Basic test script to demonstrate functionality with a low-voltage dummy load Required Skills: ESP32 development (Arduino IDE or equivalent) AC mains relay integration (safe, isolated) Experience with energy monitoring ICs Understanding of safety standards for prototype electronics Preferred Skills: PCB design experience Prior IoT or smart home device development Ability to provide recommendations for enclosure layout Budget: $500–$800 (adjustable based on experience and milestones) Timeline: 3–4 weeks to working prototype Notes: Prototype is for testing and demonstration purposes only. No mass production yet.
