Overview
ESPectre is an innovative, low-cost motion detection system that leverages the power of Wi-Fi signal analysis (Channel State Information - CSI) with seamless integration into Home Assistant via ESPHome. It offers a privacy-focused, camera-free, and microphone-free approach to sensing movement within your environment.
Key Features
- Wi-Fi Based Motion Detection: Utilizes disturbances in Wi-Fi signals to detect movement without any additional hardware like cameras or wearables.
- Privacy First: Operates entirely without cameras or microphones, ensuring the utmost privacy for your living or working space.
- Extremely Affordable Hardware: Requires only an ESP32 device (ESP32-C6 and S3 recommended, around €10) and your existing 2.4GHz Wi-Fi router.
- Effortless Home Assistant Integration: Native integration via ESPHome provides automatic discovery and easy management within your Home Assistant dashboard.
- Penetrates Obstacles: Wi-Fi signals can pass through walls, enabling detection in areas not directly visible.
- ML-Powered Detection (Experimental): Features a cutting-edge, on-device neural network for motion detection that requires no manual calibration.
- Simple Setup: Designed for users with basic YAML knowledge, with a quick setup time of approximately 10-15 minutes.
Typical Use Cases
- Home Security: Receive alerts when unexpected movement is detected while you're away.
- Smart Home Automation: Trigger lights, heating, or other devices based on room occupancy.
- Elderly Care Monitoring: Track activity levels to detect falls or periods of inactivity.
- Energy Saving: Automatically turn off appliances or climate control in unoccupied rooms.
- Child Monitoring: Get alerts if children leave their rooms during nighttime.
