Weather Station reporting precepitation and lux when there isn't any

Hi all,

Hope I’m writting this in the right place and someone could help me.
Is there a way to know from where exactly is a device pulling data from, in this case a Weather station I have on smartthings that someone gets almost everything right except for Lux and precipitation.
right now it doesn’t rain for more thna 8 days but the precipitation keeps showing numbers, same thing for Lux, right now it’s 2am, no light or moon to create any type of lux on the station sensor, if I check weather underground I see 0 lux, 0 uv and 0 precipitation but again in the app I keep getting values…
