How to import historical data from Vantage Pro2

[D Brett]

I am sure this has been covered before, but I could not find it.  The closest I could find was an import utility which was not very clear to me.  It did not look like it could import the files my software creates.

I have been using Davis Vantage Pro2 and software for windows software they supply, for years.  I would like to be able to import this data.  What I would like to do is import the years worth of data I presently have.  The start importing the daily data, until I feel comfortable with weewx.   Would somebody be kind enough to point me in the right direction for instructions on what I need to do? 

thanks

Hi,

The answer is 'sure, but we need some more info', basically where is your data and what format is it in? You say 'I have been using Davis Vantage Pro2 and software for windows software they supply, for years' - does that mean you have been using WeatherLink? At the moment the wee_import utility does not support WeatherLink directly, but that does not mean all is lost. I have never used WeatherLink myself (as many do I opened the box, kept the hardware and tossed the software) but does it have the ability to export observations in some sort of formatted text file (eg csv). If so that should be able to be imported with wee_import (maybe with a little massaging). Don't worry about daily/weekly/monthly/yearly summaries, weewx will calculate those, we just want the raw archive records. Is your data on weatherlink.com? If so wee_import cannot import from there.The key is getting your data into a state that wee_import can import, or alternatively I can add another source to wee_import, but that will take me a little time.

As I recall, wview had a utility to import from the .WLK files used by weatherlink to the sqlite database used by wview. Because weewx uses the same schema as wview, this might be a viable option.

Sometime ago I wrote a small piece of C code to translate wlk files to CSV. Maybe it is a option for you if the utility from wview (Thomas post) does not fit your needs.

Please, contact me if you need the C code.

Best regards,

Guilherme.

Sorry for the long delay in responding.  Life getting in the way of important things.

gjr80, I would be willing to supply the files to add this functionality to wee_import.  I would be surprised if I am the only person who would find this useful.

Thomas, I was not able to get it to work on first attempt.  I will try again, before looking for help.

Guilherme, The C code sounds interesting.  Is it written for windows of Linux.  Either is ok for me.
