I've noticed a constant thing with the UV sensor on my WMR200. Since original purchase nearly 2 years ago I've noticed the sensors accuracy has drifted. compaired to other UV readings I get from Wunderground. I want to add a UV sensor to the VP2 to compair with my WMR200 but for right now It's not possible. First summer bearly read above 8. Last summer bearly hit 11. This summer we're getting 15. I'm wondering if this is anything to get concerned about. Would it be time to replace or should I hold onto it?

its either caused by fading (by the UV) of the lens cap/cover (replace that)
or actual damage to the sensor by the UV
