About this deal

Give your device a meaningful name, such as "bathroom-presence" or any other descriptive name that suits your setup. Provide visual configuration tools that can easily configure sensing distance range, sensing sensitivity in different intervals, and unmanned delay time to meet different specific application requirements. I’m not sure why somebody specified the B model, because the C model also has bluetooth, etc it’s just in a more friendly form factor. Rest assured that your package will be handled with care and tracked throughout its journey to provide you with peace of mind. In today's blog post, we'll guide you through the installation process of presence detection using the LD2410 sensor, an affordable and highly sensitive sensor capable of detecting even the tiniest movements.

I have a bluetooth proxy set up via ESPHome Bluetooth Proxy which works very well and has been solid since I set it up. Multi-level intelligent parameter adjustment can be realized through Bluetooth or serial port to meet the needs of scene changes, visual debugging and configuration tools. If there is, it’s likely done through the HLKRadarTool, a phone app that lets you configure/reprogram the devices.

More precisely you should insert the password as it's done in the simplified version (I found that this increases reliability) and disable the switch that let's you turn on and off the sensor (this allows the first connection).

I have just set logging of the HA bluetooth manager to debug for an hour, and there has been exactly one entry for this LD2410C device, but I still can’t add it to HA. As I said above, the Bluetooth support in Home Assistant is also a must, as the sensor will send its data over Bluetooth Low Energy protocol, so that some useful Home Assistant automations can be created. Additionally, we offer secure payment options through PayPal, one of the most trusted and widely used payment gateways in the industry.

Unavailable status usually means the esp gets disconnected from wifi rather than sensor from the esp. This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. Not sure about the use case for this one; it seems inferior to the LD2420 generally unless you wanted to use it with a 5V MCU like and Arduino. In was reported before in some threads that power consumption of this module is “significant” comparing to for example PIR modules.
