How to emulate a PICED style "pulse" on for a GA in a SHAC scene

    Changing over an old CTC to SHAC and the motorised shades have a scene in PICED that pulses the GA on for a set time period.

    Is there a simple way to achieve a similar function in the SHAC?

    The existing system uses the 4 channel changeover relay for the motors and the pulse/time function simply disconnects the mains power after travel. Don't really want to swap out to shutter relays.

    TIA for advice and support.

    There is a "Pulse C-Bus Group" function in the logic scripting.

    I haven't tried it myself, but if you were to just turn the group on as part of the scene, you could then have an event based script triggered off the same group, which pulses it for the required time, which would just end up turning it off at the end of the pulse.

    Thanks Nick for the info. Will check the sripting options and see if I can get it work.

    Got this to work fine using the following script:


    if (GetTriggerLevel(17) == 255) then
    -- Set group 'Kitchen' on application 'Lighting' in network 'Local' to 255 over 4 seconds and after 5 seconds and reset to off.
    PulseCBusLevel('Local', 'Lighting', 'Kitchen', 255, 4, 5, 0)
    end


    Might be helpful for others.

    Thanks Nick for pointing me in the right direction.
