    PIR sensor has 4 wires. Are the grey and black both switching live? Will it matter which one i use?
    I have connected the live from the light to the grey wire from the PIR. The live from the PIR goes to the mains. Is that Ok.
    The light switches on when the light switch is on so i will see after dark what happens next.

    Can't tell. Can you look at the PIR connections?

    I would think so.

    Normally, when the supply is turned on, the light does come on for a while.
    How long have you waited to see if it goes off?
