Seeed SenseCAP Watcher Pro (ESP32-P4 + Himax WiseEye2)
Open-source physical AI sentry agent combining a 2mW Himax WiseEye2 Arm Ethos-U55 vision trigger chip with an ESP32-P4/S3 host and rotary RGB touch dial.
Key Engineering Highlights
- Tell it in plain English ("Alert me if the 3D printer spaghetti-fails or the cat jumps on the stove") and it compiles the watch task automatically
- 100% open-source enclosure, Node-RED plugin, and local Home Assistant integration
