Why: there is an action with technical schools in Portugal (good news) but they also use: https://pm.chillibits.com/
which is very fancy.
I notice that a school in Viseu shows a pressure of 960mb in this application. (email not answered).
I have a contact with ASPEA, I raise this problem which concerns several Portuguese schools: the discussion stops!
Two solutions: either I give up and it's a pity for their reputation, or I go through another way.
End of off-topic.

Toby, isn't a problem specific to a school in Viseu - Portugal. Hundreds of stations on that map, in several countries, report a pressure of 960mB, I think that happen because they don't have a pressure sensor installed (and it isn't required).
People are still learning on this field... is better be doing something than nothing.
