Make sure to enable Radar Engineering Mode in the configuration before adjusting the gate and toggle it off once you are done. I heard about the LD2410B sensor from Paulus, that is the Home Assistant founder, as he mention it during one of the Home Assistant meetings. This module gives real-time detection results and it is perfect for indoor use, but it is also rated that can work from -40 to +85 degrees Celsius, so I guess if you waterproof it somehow it can be used outside as well. I then unplug it and then wait, power it back on, and same thing - works for a few minutes, then "unavailable".

LD2410B is a high-sensitivity 24GHz human presence status sensing module developed by Hilink Electronics. Motion detection works and HA sees motion, but this makes a very noisy wifi client and can have impact on WIFI network/router performance. It only exposes 1 entity for occupancy ( or presence if you prefer) but it is still possible to configure the sensitivity etc.but I want to connect over bluetooth not have to dedicate another ESP device to make a UART connection. The radar target entity consolidates both states, requiring both to be clear for the overall presence to be considered clear, and vice versa. Combined with radar signal processing and precise human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. This has to be done by putting in the yaml only that sensor, that means 3 bin files total for 2 sensors that have to be flashed.

I'm lookup to supplement my ESP32-based room monitoring modules with millimeter-wave, and have been attracted by the LD2410, which looks to have a decent mix of affordability and capability. And for the short moment I managed to get power to the board before soldering, I saw the board pop up in HA and give me rapidly updating presence and motion detection events.It utilizes FMCW frequency-modulated continuous wave technology to detect human targets within a defined space. During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online.

This one can operate with just 5V power and can both be calibrated and monitored over BLE, although some folks have said the range and connectivity is a bit spotty. This guide uses the LD2410 model, without B or C, but the examples and wiring diagram bellow can be used for any of the LD2410 models. As end result, I will have a new device inside Home Assistant with several entities/sensors and now I can start creating Home Assistant automations and scripts.With native ESPHome support, the LD2410 can be fine-tuned to eliminate false triggers and optimize the sensor for your space. 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. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. The reason to use Bluetooth is so that you can have multiple ld2410b sensors and relocate them around their esp32 hub.
