The Budderfly IoT-Ready Energy Monitoring Device is a next-generation replacement for traditional mechanical lighting timers used in commercial settings such as restaurants and retail stores. Designed to enhance energy efficiency and reliability, the system integrates embedded hardware, smart scheduling, and cloud-based control through Wi-Fi connectivity. The device enables up to six configurable on/off schedule points per day, based on fixed times, sunrise/sunset offsets, or store operating hours. Once configured via the Budderfly network, it operates autonomously without requiring constant internet connectivity. The system measures voltage and current with ±1% accuracy and transmits performance data to the Budderfly cloud for analytics and monitoring. Hardware design supports loads from 15A to 50A at up to 277VAC, includes modular configurations for higher currents, and features LED status indicators alongside a simple On/Auto/Off control knob. It is engineered for durability - rated for at least ten years of daily use - and designed to meet UL/ETL certification standards. Built around the ESP32 microcontroller, this device exemplifies the integration of IoT, power electronics, and cloud communication to modernize legacy lighting control systems, reduce maintenance costs, and advance Budderfly’s mission of sustainable, data-driven energy management.
