    Hi all,
    I'm in the process of planning a new build, and already thinking about how to make the most of my CBus install. Note I'm an electrician however this will be my first experience with the programming side of things. (Currently doing the online fundamentals course).

    I plan on having a dedicated PE Cell on an exterior wall that doesn't have any lights. I'd like to use this to trigger outdoor feature lighting at sunset.
    However I don't want the lights to be on all night, just for say 4 hours from sunset.
    Is this possible in toolkit or is more advanced programming required?

    You can't do this with a PE cell but you can with a PIR sensor. like the 5750WPL or 5753L. Both of these have a sunset functions that turns a group on at sunset and off after a specifed time or sunrise, which ever comes first.

    Ah okay good to know. I guess theres not much use for a dedicated PE Cell then...
    Can we use the function you described to perform actions with multiple groups?
    For example, all external lights turn on at sunset with a 4 hour timer, however after the 4 hours one group of lights (front porch) will still react to movement until sunrise.

    The sensors have 4 functions. Movement in light, movement in dark, sunset/sunrise and any movement. Generally movement in dark and movement in light use the same group because when movement in dark turns the light on, it puts the sensor in movement in light mode, although you can trigger different groups during the day and night. So, yes, you can do as you say.
