HLK-LD2410C is a high-sensitivity 24GHz human presence status sensing module developed by Hi-Link Electronics. Zone 2 starts where Zone 1 ends, so if Zone 2 is set to 300cm, it detects presence from 50 to 300cm measured from the sensor. I can’t say, yet if the root cause of this high delay is the Bluetooth integration or my PC or both. Note: Depending on your device, you may need to hold the boot button before installing the firmware.

To create your own presence sensor based on the Hi-Link LD2410, you are going to need a couple of things. But other than that it is a very clear article, I had not yet come across defining zones and I will certainly incorporate them into my config. The reason to use Bluetooth is so that you can have multiple ld2410b sensors and relocate them around their esp32 hub. Configuration can be done with ESPHome YAML and it is not necessary to calibrate it with a CH340-and-computer setup. home-assistant unassign ld2410_ble Removes the current integration label and assignees on the issue, add the integration domain after the command.I have the LD2410C and it immediately shows up in the app and appears to work fine, but multiple nearby bluetooth proxies (which otherwise work fine) are not detecting this device at all. Supports GPIO and UART outputs, plug and play, and can be flexibly applied to different intelligent scenarios and terminal products.

In this article, I am sharing a DIY guide for creating a simple presence sensor based on the HLK-LD2410 sensor and an ESP32 board, all coded through ESPHome and Home Assistant. You can simply attach the standard Dupont connectors from the ESP32 Board to the sensor and you are done. Rest assured that your package will be handled with care and tracked throughout its journey to provide you with peace of mind. During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online.With support for GPIO and UART output, it offers plug-and-play functionality, making it adaptable for different smart scenarios and terminal products.
