Hello all - I spent a day over easter playing with my system, hence my renewed activity on the forum..
I have installed 3 GJD Opal PIR's for controlling my exterior lighting. Only problem is that the output for the passive is designed for the GJD control panel, which responds to an open collector negative going pulse from the PIR - exactly the opposite of Cortex's DIO requirement (held negative, going o/c on detect and pulled high to 3.3v).
Is there any way to alter a DIO PIR object's input so it responds to a -ve pulse rather than held -ve, going high on alarm? I did have a play with logic functions but couldn't get a logic output to drive a virtual PIR.
I could just buy some low power relays to create the condition required by the software, but I hope I can find a more elegant software based solution.
I have tried using a proximity input but it appears that they can only be associated with a door and can't directly infer presence to a room.
Any suggestions welcome.
