Thank you for helping. I will use StdCalibrate to get exact value of solar radiation. About preassure, I use absolute preassure which is higher than sea level preassure, my altitude is 293m (I have this setting in weewx.conf). When I checked my absolute preassure it was about 1008mbar until sea level was I think about 995mbar. But I have always set to absoulte preassure and when is absoulte preassure 1010mbar weewx shows 1008 mbar. Rain starts to show up after about 25 minutes but need to be calibrated value is too high. I have hardware to measure rain rate. Console show rain rate 18mm/h until in real is about 4mm/h. you can see on vreme.povej.net
