1st test can be to listen at the housing of PIR sensor when it get's activated. If a clicking noise can be heard, the chance that it is a compatible sensor are not too bad.
But still there can be electronic components before or after contact, which can make it incompatible.
On open SW input of the Shelly one can measure approx. 1/2 grid voltage (needed to use the Shelly for activating if Life or Neutral is used).If this 1/2 grid voltage (in our region usually 230 ... 240VAC) gets too much influenced (pulled up or down) by use of not 100% dry contacts, the Shelly always see's a high Input on SW.
Hi,
I hear the clicking but shelly 1 doesn‘t recognize any of the pir state.
When PIR detects a motion there is a voltage on the SW.(Tested with the voltage test screwdriver) 😊
Shelly doesn‘t seem to see any voltage on the SE input.
Any idea why?
Thanks!
Ach, PIR is GTV CR-7 for indoor.
