LockyFi – A Compact, ESP32-Powered 4G/2G/Wi-Fi Remote Switch for Smart Automation, Launched on Kickstarter

 Uzma Mohsin, a tech innovator from West Midlands, UK, has just launched LockyFi, her third Kickstarter campaign. With a track record of successful projects, Uzma has previously developed the Serial Servo HAT & Expansions, a versatile module designed for building robots and automation systems, and the UHF Reader: Rapid Multi-Tag Reading, a high-speed RFID reader capable of reading over 50 tags per second within a 1.5-meter range.

Building on this success, LockyFi is a smart 4G/2G/Wi-Fi Remote Switch Controller that offers seamless remote appliance control. Powered by an ESP32 microcontroller, this compact and innovative board supports multiple control methods, including SMS, calls, internet, and Wi-Fi. Designed for home automation, industrial control, and security applications, LockyFi enables users to control and monitor appliances effortlessly from anywhere in the world.
