Solar Chart

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Solar Chart

Post by Herbaldew »

I moved my solar/UV sensor to my anemometer mast and it looks like my plot is shifted slightly to the right of where it should be. I doubled checked that the sensor is level.

I never noticed this before, though my plot was a good bit higher than the theoretical max in the past so maybe not as noticeable - I didn't know it could be adjusted via the transmission factor.

Any guess on what is causing this?

Thanks

It's one of two things: either your latitude setting is off, or the sensor is not level - it doesn't take much to be noticeable on the graph. ;)
