Hi truglodite
Run my 501’s with cable lengths of 5 - 20cm on breadboards. After successful test operation the connections are then shortened and soldered.
I am interested if the 220nF mod works for you. Let me know.
I’m gonna order some of those 312 motion detectors to test as well.
Also experimented with the rcwl-0516. Combined with the PIR, they make a perfect pair for reliable presence detection.
I built a test circuit with addressable LEDs as status indicator for each sensor. The LEDs give immediate feedback and help to fine tune the system.
ESPHome makes everything so easy. Awesome!
