Hi folks. Sorry for the late response. Just wanted to let you know we’ve been looking at the UV data across all SKY units (more than 1000 in the field now!) and about 10% of them do indeed seem to be significantly out of calibration - some too high, others too low.
Fear not! The vast majority of these cases are simple calibration issues, and will be corrected over-the-air, auto-magically. A small handful seem to be bad sensors (or maybe something covering them, as suggested). If you think yours is bad, please contact support for one-on-one help. If you think you have a calibration issue, especially if you have specific comparison reports (like @ptsdds), please share them here. It will help us improve things!
Could you please put my sky #2 in the beta group. I have two Sky’s on the same Station (2809), 800mm apart. Sky 1 (9662) is tracking very similar to other stations around me(Weather Underground ones). Sky 2 (9849) is about 25-30% less. Solar Radiation is almost identical. Its winter now so UV is low.
I have noticed my UV readings are far too low as well. This has been the case since it was installed (7 feet above a roof top with no possible shade) several weeks ago. There are a couple DAVIS units nearby that show a UV of around 10 or so when mine only shows around 5 on a bright sunny day.
Could you add mine as well please - I am not sure if mine are too low of not (peaking around 4.5, but various other sources say to expect higher), but would be good to check and see if the CL beta increases it. Station ID is 2197.
Could you add my Sky to the group also? I live in SE Louisiana and I’ve never seen a UV number over 2.8 which seems awfully low. My Sky is on the roof in clear sunlight. Station ID is 3971. Thanks.
