ESPHome firmware for ESPresenceLD sensor (ESP32+LD2410x)
Installing ESPHome on hardware with a minimum of 2GB of RAM (4GB is recommended) is crucial, otherwise it may not be able to compile the firmware properly. The setup process of your Home Assistant can be smoother with Bluetooth enabled, as it autodiscovers, adopts, and compiles the latest firmware available.
