Hi Galfert and Johnd.
Firstly many thanks for your help, what I thought to be a simple question has become somewhat complicated, sorry, and it appears to be changing on a daily basis. The WL barometer box with no data
now has data in it,
perhaps I should have been more patient. I think this proves the box does not show graphing data, although that is what it appears to be as I would have to pay a sub to allow graphing data.
There appears to be some confusion, probably due to my explanations. So to clarify, the little Samsung laptop, is acting purely as means of downloading data from the Vantage Vue console and uploading it to both WU and WL.
It's only running W7 due to it being incapable of running W10. It just sits there doing this, no updates and no other use. It just works, abit with the occasional hiccup. I hope this has made the operation clearer. I'm not using the little laptop to access anything, including WU or WL, only to upload data to both of these.
My main PC runs W10, it's fully patched and has no problems. It, and the Apple apps, are used to display WU and WL.
The Avast popup turns out to be due to a Chrome 'Notification' which appeared to coincide with my opening WU. I have now dealt with this.
Therefore with your reassurances, that WU is OK, I will carry on using it on the PC, and use the apps on the phone and pad when, and if, required.
Regarding your comment that the iPhone XR and iPad have a pressure sensor, you are indeed correct. I'm still uncertain as to whether the barometer data displayed is obtained from the data provided by WL, or from the internal sensor, however this is not really important as it works.
My Davis Vantage Vue display does show barometric pressure. I believe that it, and everything else WU, WL and surface level charts, all show pressure at sea level, as this is easier to compare. This can, if required, be altered to show station location pressure, by altering the settings in the Consul manual.
Many thanks Noel
