描述

Implement a "low power mode"uses camera and other high power sensor more efficiently, by triggering them from low power sensors

sound + light sensor -> trigger camera activate and/or video recording

light, motion -> trigger one minute of active camera motion detection -> trigger one minute video recording

研究方向
Study the existing sensor usage in the Haven app, particularly how the camera and motion sensors are currently triggered. Review Android's SensorManager and PowerManager APIs to understand low power sensor batching and wake up triggers. Look for any existing power saving patterns in the codebase, such as Doze mode handling. Then design a proposal that uses sound and light sensors as low power triggers for the camera, ensuring minimal battery drain. There are no comments or linked PRs, so the approach is open for discussion.
