All sensors are "Unknown" after compilation and upload

[miljume]

All sensors become "Unknown" (Okänd = Unknown) after startup
Sensor used HLK-LD2410B from [https://www.aliexpress.com/item/1005004673573740.html?
Sensor works fine with HLKRadarTool

Can you share your wiring for ld2410?

[miljume]

Of course, see below:

ESP8266 | LD2410
5V <-> VCC
GND <-> GND
TX <-> RX
RX <-> TX

I am in the same boat with a D1 mini. I don't see any uart data when viewing the logs remotely with debugging on. The output pin seems to be working though.

Im powering the LD2410 from the 5v pin on the D1 mini, i tried 5v directly from a power supply as well to the sensor and that didn't make a difference. Any other ideas why the sensors show unknown?

Below is my YAML as well in case it helps.

I swapped over to using RX = GPIO13/D7 and TX=GPIO15/D8 on the D1 mini and now I am getting uart data. Leaving this here in case it helps someone else.

[n1kDon]

@cmille34 Wow that worked!!! Bought 5 more after the first one worked flawless. There was no uart data on all of the new ones. BIG thanks, I dont know why but now it works! I've been messing around with these things for 2 days.

@rain931215 maybe you should point this out in the docu

@cmille34:
Can you please attach both your .yaml file and your .h include?
Cant get it to compile

Below is my full yaml (Sorry if the formatting is all messed up). My .h file is the one from this repository. I didn't mess with that.

@cmille34 Worked perfect, thanks a lot!
