Everything Presence Lite mmWave Presence Sensor ESP32 Home Assistant

The Everything Presence Lite is an ESP32-based mmWave presence sensor specifically designed for integration into Home Assistant and other smart home systems. The device was developed by Everything Smart Home and is made in collaboration with Seeed Studio. Unlike traditional PIR motion sensors that rely on heat signatures, this sensor uses mmWave radar technology, detecting even the smallest or slowest movements as well as the presence of stationary people. All data processing is done locally, eliminating the need for cloud connectivity and preserving privacy.

Features:

• Detection range of the included LD2450 is five to six meters and covers small to medium-sized rooms
• Multi-target tracking tracks up to three people simultaneously with information on position, speed, and angle
• Zone configuration allows up to four detection and two exclusion areas directly from Home Assistant
• Light sensor BH1750 measures ambient brightness and enables adaptive lighting automation
• Bluetooth proxy function extends the range of Bluetooth devices within the Home Assistant ecosystem
• Compatibility with several mmWave sensors allows for flexible experimentation and development

Application Examples:

• Automatic light control that turns on when entering a room and deactivates when absent
• Heating and climate control based on actual room occupancy to save energy
• Detection of sleeping people in bed by capturing fine movements like breathing
• Intrusion alarm or security system that responds to presence in specific zones of a room
• Intelligent presence detection in offices or meeting rooms to control lighting and ventilation
