DataExplorer is a 3rd party (multi-device) data logger that also works with this charger. It cannot control the charger, just read the data from the USB port. It has the advantage of at least working on Linux (after the Udev rule is applied as per its instructions to read the USB port).
DataExplorer is useful for exploring the graph stats in detail. For example in the video you can see that slot 3 is charging quicker and that its internal resistance is lowest (healthier battery than the others with higher IR).
