Home Assistant custom component for integrating LD2410 mmWave presence sensors over a direct serial connection. It is based on the ESPHome LD2410 implementation: https://github.com/esphome/esphome/tree/dev/esphome/components/ld2410. This integration exposes similar entities and does not require an ESP32 board. It has been tested only with the HLK-LD2410B.

1. Open HACS in Home Assistant.
2. Search for "LD2410 Serial" and install.
3. Restart Home Assistant.

1. Copy the custom_components/ld2410_serial directory to the custom_components directory of your Home Assistant installation.
2. Restart Home Assistant.

Go to Settings -> Devices & Services -> Add Integration, then search for "LD2410 Serial". You will be prompted to provide a serial port (for example, /dev/ttyUSB0 or /dev/ttyS1).

The integration supports changing the detection gates, as well as the timeout.
