Ginlong solar inverter scrape

README.md

Here's an example flow for collecting plant and inverter data from the new ginlong monitoring website. http://m.ginlong.com I had a previously used ginlongmonitoring.com but that is being replaced by the newer website. I had to re-register for m.ginlong.com, and then enter the serial number for my inverter's wifi stick - after half an hour the new dashboard was populated with data.

The new website is easy to parse and pull data from - it provides a number of json feeds.

The LoginDetails node should be edited to include your login username and password for the new ginlong website.

The final function node should be edited to set the appropriate Domoticz idx values. My inverter has two input strings if you have a different amount you should edit appropriately. If you're not posting out to Domoticz, edit as appropriate.

The msg in the final function has accumulated several properties which hold interesting data: msg.plantData msg.inverterData msg.inverterDetails

Hope this is useful.
