They do offer Windows based software. But I need to automate the gathering and processing of the data (and this is not for revenue purpose), and that needs to be done on Linux. It is possible that they use a proprietary or maybe even encrypted data format to send to a computer to force they use of their own software. Many companies are known to do that even if they give their software away. I'll be giving E-mon a phone call or sending them some email after the holidays, to see what they can tell me, and suggest a specific product.
