SHS01 – Zigbee mmWave Presence Sensor [ESP32-C6 + HLK-LD2410C]

This project provides open firmware for building your own Zigbee mmWave presence sensor using an ESP32-C6 development board and the Hi-Link LD2410C radar module.
It runs as a Zigbee router, so it helps strengthen your mesh while providing reliable human presence detection. Firmware works with the LD2410, LD2410B, LD2410C and can be adapted to the new LD2412 (Work in progress, SHS02).

Current status

• ✅ Power configuration fixed
• ✅ Zigbee router mode enabled
• ✅ Occupancy, moving target, and static target states exposed
• ✅ Configurable cooldowns, sensitivities, and range gates
• ⚠️ Still under active development (expect changes)

---

Features

• Dual human presence detection (moving + static targets)
• Zigbee router role (joins existing network, strengthens mesh)
• Custom configuration cluster (0xFDCD) with attributes for:
  • Movement cooldown (0–300s)
  • Occupancy clear delay (0–65535s)
  • Moving sensitivity (0–10 proxy → 0–100 internal)
  • Static sensitivity (0–10 proxy → 0–100 internal)
  • Moving max gate (0–8)
  • Static max gate (2–8)
• Persistent storage in NVS (settings survive reboot)
• BOOT button reset (hold for 6s to factory reset Zigbee + restart)

---

Hardware

• ESP32-C6-WROOM-1 development board
• Hi-Link LD2410C mmWave radar sensor (UART1, 256000 baud)
• USB-C or regulated 5V power supply

---

Firmware Notes

• Built on ESP-IDF + esp-zigbee-sdk
• Based on Espressif’s ha_dimmable_light example
• Minimal dependencies, lightweight and stable
• Exposes attributes to Zigbee2MQTT (via external converter)

Setup

1. Install ESP-IDF v5.1+
2. Clone this repo
3. Build & flash:

   idf.py set-target esp32c6
   idf.py build
   idf.py -p /dev/ttyUSB0 flash monitor
