Hi guys, its not reading -- just 0.0, for similar full sunny days last January (2021) i was seeing 0.7 max UV, max solar for that day was 420, the other day it hit 470 with UV 0.0, i believe it doesn't register till 0.5, so at the very least i should see 0.5 at 470

Granted, i cannot rule out bird doody, but that is very unlikely because they do not perch up on there, they stick to the older OS anemometer that's a little higher up, not once have a seen a bird on the Davis, many times a day i see doves or pigeons on the OS, i set it up that way so they will leave the Davis alone
