Multisensor 6 UV sensor

 Is there a consensus as to wether the UV sensor actually reports a reading other than 0 with current firmware for the Multisensor and latest VERA UI7?

Mine is reading a steady “0” despite doing a test with an actual UV source (both short and long wave). Aeotec says to perform the test with the unit outside a window for a few hours, but after a test with an actual source, I’m not persuaded that an “outside the window” test is going to read anything but “0” as well…
