    I have a SENLL (firmware 1.0 mounted so it knows when the sun is beaming ON the window.

    Using tool kit I can get the Ambient Light Measurement

    Sun Shining on window 5600 Lux
    When the Not shining but still day the measurement is 2100 LUX
    At night 0 LUX

    I want a blind to operate when the LUX reaches 3000

    I put the group address for blind control in the On/Off section.

    My issue is the TARGET Slider ONLY goes from 0 LUX to 1598 LUX.

    Any way around this ??

    I noticed a calibration adj on the side. could I change this to bring down the reported measurements to the range the TARGET Slider can operate with ??

    (and totally stuffing up the callibration !)

    SENLL is not intended to measure daylight levels; it's intended for indoor use.

    I suggest you move the sensor a little further from the window so it's not so bright.

    In the weather proof model any different ??

    Will it still broadcast the measurement OK ? I will then do the switching in the logic engine.

    I know fiddeling with the calibration will void the warranty but would that work also. I dont realy care what the actual LUX is.

    I wouldn't expect a weatherproof version to have a different range.

    You could always put something in front of the lens to reduce the light levels the unit sees. a partial shade, translucent material or a semi-transparent material would work fine.

    I wouldn't fiddle with the calibration, but that's just me :)

    Good idea a quick spray of the front with white paint did the trick.
