Error during accelerometer data streaming - lis2dw

I picked up a used V-Minion the other day and have been trying to get it up and running. I've added a BTT S2DW board under the bed. I'm able to get Klipper communicating with the sensor over USB, however I'm not seeing anywhere in RatOS to specify anything being there being a connection to the host; Nothing specifying the actual sensor type outside of Klipper .cfg files. This section of my printer.cfg that specifies the sensor comes at the end:

When I start a stream on the Realtime Analysis Tool, I get the following error: 
Error during accelerometer data streaming:
Error: WebRequestError: Invalid adxl345 id (got 0 vs e5).
Error during accelerometer data streaming:
Error: WebRequestError: Invalid adxl345 id (got 0 vs e5).
Is this result expected? Does the analysis tool currently support the S2DW?

Yes the lis2dw is supported but usb accelerometers aren't. Only the sources listed in the realtime tool (ie, toolboard, controlboard, pi/host or beacon)

I see. And is that for technical reasons or performance reasons? Rather, is it something that some extra developer effort could help resolve?
