I think this add-on is what I would like to implement. Only, I have a SMA Sunnyboy 3000TL inverter. The operational data is accessable via a portal, www.sunnyportal.com. So scraping the data from that one and using it in OpenHab2 is on my wish-list.
I would like to use the current power from the solar panels to manage the charging of our electro car by the solar panels.
Would it be possible to add the reading of the SMA Sunnyportal (scraping) to the Kostal inverter binding, or could we create a SMA one based on the Kostal one?
