I gave it a shot, but it comes in a .kmz file which the converter doesn't handle. If I unzip it, I can open it in Notepad and see some data.
But it appears that it's all strikes in view based on how you have the map zoomed and not just those for your sensor. That doesn't really do me any good. I want to see the ones my sensor has detected. That may require the USB bit.
skipped a step: "After you receive the .KMZ file, rename the extension to .zip and unzip the file. You get a .KML file that contains all of your strikes in text. " It is the KML file that you convert.
If you want more data - zoom out.
You are right about what our individual sensor detected. There probably is a lightning map lines equivalent somewhere, but not one that we get to see. USB "strokes report" only advances the stroke count, there is no specific single stroke data there, that would be nice.
It might be possible to mirror the ethernet port with an ethernet switch (or a router with port mirror capability) to look at the individual reports, however they probably need to be decoded, not sure how difficult that would be with something like WireShark.
On the other hand, the time of the report based on local computer time could work, if the detection rate is low enough to just watch all of them simultaneously.
