I've recently discovered that my pressure readings may have been incorrect. I setup to share my data with AWEKAS and within a day or so my pressure readings were locked as they did not fit with surrounding stations. I share through cumulus, so the first thing I did was check what was going on there - but it seemed fine. I checked the display and the figures were matching what was going out - however one thing I do notice is that relative and absolute pressure are the same? I live 30+ miles from the sea and on the side of a valley, so I don't think that should be correct.
I started to write this and went to take a screenshot and noticed that within the last day or two, suddenly my readings are matching again - I don't think I made any relevant change to settings, I was still trying to convert millibars to hpa to understand what it should be - and I didn't want to recalibrate anything until I understood what was going wrong.
So yay - my data matches the few surrounding stations within 20kms. Still doesn't explain A: why and B: when I switch between ABS and REL on the display nothing changes? Does anyone have any thoughts on this phenomenon?
Thanks!
