Since 2003 I run a weather station in Koblenz Lay/Germany. At first this was a WS2500 weather station manufactured by ELV. To run the station I wrote my ws2500 software that allowed me to extract data from the station, insert it into a MYSQL database and finally present these data graphically in a web page.
Meanwhile, this station is no longer manufactured and no longer sold by ELV. Therefore, a new acquisition was inevitable. The choice finally taken was a Davis Vantage Pro 2 station.
After purchasing the Davis Vantage Pro 2 the question was of course how to extract data from this station and how to avoid a break in the display of old and new weather data. After all, there was already old data of about 8 years from my old ws2500 station. This data should of course remain intact and accessible. In addition visualizing weather data should be seamlessly, they should be no visible transition betwenn the old ws2500 based data and the new data coming from the Davis station.
