Engineer Implements LoRa Wake-On-Radio Camera Power
William Lucid describes a LoRa Wake-on-Radio system that powers a Wyze Cam 3 on demand using the Ebyte EoRa-S3-900TB (ESP32-S3 + SX1262). The battery-powered receiver draws about 174 µA in deep sleep, wakes on a web-triggered LoRa preamble, and provides a 120-second live viewing window before automatically powering down. The project includes hardware fixes, firmware, and Arduino setup instructions.
Scoring Rationale
Practical, well-documented IoT implementation with clear instructions; limited novelty and niche embedded-systems scope constrain wider impact.
