The last release of Omnikdatalogger supports logging to a CSV file. Additional the local time, date and temperature (Openweathermap) can be logged. CSV logging can be configured per inverter or aggregated.
To already try the new feature download the new release.
Omnikatalogger’s tcpclient suports direct connection over port 8899 to fetch the data using Wouter van der Zwan’s library. Not all inverters support this way of connecting. Some inverters support collecting the inverter data over HTTP. With the new release the tcpclient will fallback to this http method when it fails to fetch the data over port 8899. Omnikdatalogger will try to fetch http://{inverter_ip}:80/js/status.js and will try to extract the data. A new setting http_only at the plant specific settings will allow to configure tcpclient only to use this method.
A disadvantage of this method is that it contains less details about the inverter and misses info about the PV DC strings.
