Could be something related to different hours between the systems? ESP logs show 2 hours less than my local time

Not really, the sensor doesn’t know it.
You need to see a line like this in your log:

with <<< indicating received data.

Is it possible that you changed the default serial parameters in the app?

23

SOLVED!!!

As anticipated by you… It was a hardware issue. All the sensors I have are defective!

I used an LD2410b from Amazon and it worked directly.

Thank you all for your help and support!!

24

You found out why?
Nice that you made it at least!

25

No, it could be a wrong manufacturing process, I don’t know what, but exchanging the sensor worked directly. And honestly I lost 4 days of my life with this… so buying new sensors now…

Thanks again for your help!!

Just another four days to go down in to the rabbit hole… to find out why… in the name of science… :grinning:
