Bushman do you happen to know if this WDTU creates working MySQL tables so other programs like Excel can work with the data.
Not 100% sure what you mean but let me comment:
1. WDTU certainly can export blocks of data to Excel and this seems to work pretty well. I don't know exactly what the intermediate mechanism might be but the image at the bottom of this page on our main website:
http://www.weatherstations.co.uk/envoy8x.htmshows the Excel export interface.
2. I've only really played with the Access version of the database rather than MySQL, but certainly the Access version seems to create a fully functional database that can be accessed via standard Access readers and I've no reason to think that MySQL wouldn't be equally competent.But you will need to spend some little time understanding how the schema of the database is constructed - from memory there are 13 (or some such number) different tables involved that interact in various ways to implement the whole database. (Although 3 or 4 of them are pretty small and just define things like which wireless channels are in play and which transmitters they map to.)
