That works fine when you have an incandescent load that's 40W+ but not
when you have a CFL or LED load that's a small switching power supply.

True. Also, I have a similar motion sensor switch which is continuously
triggered as sensing motion just by the ballast circuitry in a CFL. I must
use at least one 40W incandescent in parallel with LEDs. (If just LEDs', it
ends up flashing them very briefly every few seconds when in standby, i.e.
when no motion is detected.)

followup in order to possibly enlighten someone else.
