how did you rework the still detection algorithem ? can you explain to me
What do you mean? Could you share more?
Hi,
can you please recommend a simple 3D print model for a esp32 C3 / C6 + LD2450 combo. Does not have to be the nicest. If there is space for another sensor, e.g. light, that is not a problem at all.
Thank you.
Hi,
Have you tried updating your ESP32 + LD2450 to ESPHome 2025.8? I removed the throttle line, but after the update, all entities show an “unknown” status. Any idea what might be going on?
I have the same problem after the 2025.8 update?
esp32-c3+ld2450 no longer shows parameters like the user above.
I updated mine to ESPHome 2025.8.0 with no issues. Are you using the ESPHome LD2450 component or a custom one?

Hi,

I notice you have fast_connect set. Is your wifi network hidden?
I see that someone has raised an issue with behaviour changes with wifi so it may be worth testing that and check that your ESP32 board is successfully connecting to your wifi network.
No issues with the wifi connection.
How are you confirming that your ESP32 board is connecting to your wifi successfully?
If you add the following sensors, do they display values? If they show as unknown, then your ESP32 board is not connecting to your wifi network:
text_sensor:
- platform: wifi_info
ip_address:
name: ESP IP Address
entity_category: "diagnostic"
icon: mdi:ip-network
mac_address:
name: ESP MAC
entity_category: "diagnostic"
icon: mdi:ip-network
ssid:
name: "ESP Connected SSID"
bssid:
name: "ESP Connected BSSID"
sensor:
- platform: wifi_signal
name: RSSI
id: wifi_signal_db
update_interval: 60s
entity_category: "diagnostic"
I checked the logs. But it stopped reporting data from a ld2450.
Are you able to test that the LD2450 is receiving enough power and working?
You can use the HLKRadarTool app on your phone to connect to the LD2450 via bluetooth and from there you can check that the sensor is working and detecting motion.
If it is working via the app but not in HA, then my suggestion is to downgrade to the previous version of ESPHome to get the sensor back up and working again.
I have a number of LD2450 sensors running with one using the ESPHome LD2450 component and another one based on the Screek code and both are working fine after upgrading to ESPHome 2025.8.0
Yes, i can connect to the LD2450 via BT and the sensor works. I found this in the log:
[00:31:37][C][ld2450:199]: LD2450:
[00:31:37][C][ld2450:199]: Firmware version: 0.00.00000000
[00:31:37][C][ld2450:199]: MAC address: unknown
It doesn’t look like the ESP32 board is communicating with the LD2450.
I would suggest downgrading to ESPHome 2025.7.x and verifying that all is working correctly.
Then you will know that the issue is with the ESPHome 2025.8 update.
There is definitely something wrong with the ESP32-C3 Super Mini when using ESPHome 2025.8+. I even tried switching to an ESP32-C6, and that worked without any issues.
I try, and works fine
I switched the GPIO pins from 19 and 20 to 4 and 5, and now it works.
I have an esp32d with LD2450. This is my first time working with esp32. I can see the LD2450 in the HLink app, but I can’t get it to work in HA.
I have tried several configurations, resulting in various error messages. For example, the received data is too long.
I tried this configuration and adjusted the board and pins:
And also this bin file, but via web ESPHome.

Can anyone point me in the right direction?
