ESP32 and Arduino will drive every part of this project, turning ordinary lights and appliances into WiFi-enabled devices that I can switch on or off, schedule, and monitor from a custom mobile application. The core involves designing smart switches, integrating common sensors, and pushing data to the cloud through MQTT and Firebase so I get real-time status updates wherever I am. I expect clean, well-commented C++ firmware, a neat PCB layout that is ready for fabrication, and a companion app built with Blynk IoT or a comparable framework. Android and iOS support are both welcome; feel free to recommend the most efficient route. Because I plan to scale beyond a prototype, component selection, power-safe routing, and OTA update capability are important. Clear circuit diagrams and a short hand-over video will help me replicate or service the hardware later. Post-delivery support for minor tweaks is appreciated so the system stays reliable once installed in my Nashik home. Deliverables • Working hardware prototype tested on an ESP32 development board • Complete source code (firmware and mobile app) with setup instructions • Schematic and PCB Gerber files • Cloud back-end configuration (Firebase or equivalent) • Brief documentation and follow-up support Fast, responsive communication will keep the build on schedule and ensure every feature functions exactly as planned.
