thanks for your reply, yes I had the lat and long. set to match what I have in weatherlink. on the solar set up tab, they talk about needing a minus sign in front of them if east of gmt. I have tried both ways , using minus and not using it with no difference, still showing 0 percent. the plot max solar button when pushed shows the solar w/m2 number the same as weatherlink, but still shows the solar at the 0, how does the minute offset work. try 1 minute and wait a while, or would any result show up pretty quick?
