    Default Controlling two lamps with two separate wireless PIR's

    Could someone please confirm if my theory is correct.

    I wish to install two PIR's, one at the front of the house and one at the back to switch inside lamps on as someone approaches. However I'd like both lights to operate independently of each other. I.E. front PIR switches on lamp at front of house, rear PIR does same at rear.

    Is this possible using just two lamp modules a transceiver and two PIR's?

    P.S. I'd also like both sensors to trigger an internal chime, can this be done too?

    Simple answer yes.
    Just set the the PIR to the relevant house codes on the modules. Remember to set the PIRīs to trigger only at night. IF thats the way you want it. If you don't want a controller then you would need two chime modules. Its probably cheaper to go for a CM11 or 12 and program a few macrosthen download them into the controller.
    For example set up a macro called B4 and another called B10. Front lamp module is A1 and rear one is A2 and chime is A3. Set front PIR to send a B4 when it triggers and rear PIR to send a B10 when it triggers. Now program B4 to switch on A1 and A3. You can either let the PIR send the B4 off or do it within the macro. And do B10 the same way.

    Thanks for that, I now understand how to do it.

    In order for the controller to switch the lights on at dusk and turn them off at say 12:00 do I need to leave the computer on or will the controller adjust dusk times itself?

    Once everything is downloaded you can switch off the computer. Make sure the macros are of the fast type. The fast type are if you like stand alone macros. The standard macros require the PC to be running.

    If you use the nighthawk type pirs then you will need to take into account the two x10 transmissions from each. Front could be A1 then Rear would need to be A3 to allow for the dusk dawn transmissions on A2 and A4.

    Thats why I suggested B4 and B10 for the macros.

    I have set the PIR to send B4 which works fine when the lamp and chime are set to B4 but I don't seem to be able to get the controller to work properly. I can get the macro downloaded to the CM11 but when I trigger the PIR it doesn't switch either the chime or lamp module on.

    The macro I have done is called B4 should this be set to off in the macro screen or on? How I understand it is that when the controller receives a B4 ON it should turn the lamp on chime on. I'd be grateful for the advice.

    Do I need two macros recording for ON and OFF properties?

    IF your macro is B4 then you will need to set your light and chime to different adresses say B1 and B2. Yes you will need to set up the off properties as well. The off signal time for the PIR is configurable from I think 1 minute up to about 255 minutes.

    I've set everything as per your example above. In the macro screen I have just one macro called B4 set to on linked to a lamp unit (A1) and an appliance module (A3). I assume using an appliance module is the way to do the chime as I can't see any other way of doing it.
