LD2450 Show All Unknown

jadesse · January 25, 2026, 2:01am

I am not quite sure what the issue is but I have been trying to play around with w couple HLK-LD2450’s for a few days now & cannot get them to work in HA. Everything seems to work in the HLK Radar Tool app. As I can see firmware version & live date. All the entities in HA show as unknown. I have tried several different yaml files even the one straight from the esphome website but nothing works.

When I look at the logs in esp home the firmware version just reads all zero. I tried swapping the RX & TX but that does nothing except not make the sensor work at all in the HLK app. Can someone please give me some insight?

Some simple example yaml would be preferred, running BLE tracker is likely not needed for debugging the problem.
What esp board you have?
How is your wiring? Pre-soldered headers or something else?
Firmware of your sensor?

jadesse · January 25, 2026, 4:45pm

I tried the yaml off the esp home site & that did not work. I even tried the yaml from this guys project which did not work either.

Mini DIY ESPHome mmWave Presence Sensor ESP32 C3 + LD2450 | fixtSE

I am trying to use a C3 super mini

LD2450 Firmware: 2.04.2310915

I just tried using a regular ESP32 Dev board & an LD2450 work with it. I just used the yaml off the esp home website.

I did try two different C3 super mini’s both if those worked with a VL53L0X. I is using different pins. I cannot figure out why the LD2450 will not work.

Karosm · January 25, 2026, 4:57pm

Use the code that worked on esp32, just modify the variant. Use those pins that worked for VL53L0X.

Logger might spam default uart pins at some point.

jadesse · January 31, 2026, 10:01pm

Holy Crap! that seems to have worked. At least I am seeing something now. VL53L0X uses the I2C pins. Not sure how viable of a solution this is long term though?

Karosm · January 31, 2026, 10:17pm

Of course you need to adapt it for C3 and C3 pinout.
