Sun-Watch is a data logger by Uwe Klatt. It was originally designed for private reasons. Sun-Watch supports data import from solar-yield.eu (Sonnenertrag.eu).

Sun-Watch puts a file months.js at the web index automatically every night at 11 PM. This file can be downloaded and evaluated automatically by Solar-yield.eu. In this case, the complete yield data of the last 3 months is transmitted.

For example, if you set up the Dyn-DNS address meinlogger.dyndns.org, the download address which needs to be adjusted at Solar-yield.eu is: http://meinlogger.dyndns.org/months.js
