-I'll probably have to calibrate sensor readings. Pressure seems okay but there seem to be discrepancies in the temperature and humidity compared to a nearby zigbee sensor.

 This radar isn't harder to wire than the previous two devices :

+Then you need to initialize the UART. Since we already use an UART for logs, you have to keep them from mixing up.

-The rest of the code isn't complex but there are a lot of parameters so it's quite lengthier than the previous devices.
+That prevents from getting logs on the sensor channel and inversely.\\
-<code yaml>ld2420:
+I'd rather define UART speed myself than hope the default is the good setting. As for the OT2 pin, if your LD2420 is on older firmware you may need to set it to 256000.

+The rest of the code isn't complex but there are a lot of parameters so it's quite lengthier than the previous devices. Moreover it's the default code I found on ESPHome website I did no change on it. So as of now, I'll only put what I change in the code to prevent having boring large slabs of code everywhere.

-sensor:
+So, with all this the sensor works surprisingly well. Let me be clear, distance readings are all over the place. But even if the PCB is facing the ceiling it detects me everywhere in the room. I had to go out of the room and move away from the door opening to be undetected.\\

+I guess in an open space like in front of the garage and with a well calibrated sensor it should return more accurate readings.

 ===== Now the same using zigbee =====
 I want to evaluate how harder it would be to make the same device using "classic" code and zigbee communication.
 Because most of my current devices are using that radio communications, so it would be great to keep going with it.
