FinnPlease don't judge my cabling but I am quite desperate. I got this LD2420 presence sensor working quickly using this library: https://github.com/NaeviusUAV/EasyLD2420
Changed my code several times, rebooted the ESP etc. etc. - then suddenly it stopped working. Cables are connected correctly but also tried other combinations, too (PIN layout seems to depend on firmware version).
Some research showed many people having issues with this one but could not find a solution, often the fault was Homematic or ESPHome.
Even tried a second LD2420 - no difference.
Ooooh - maybe I broke the ESP's UART?
