The results I was able to find are not promising.

The best I could come up with is to make use of this and some cobbling:

<https://moderndevice.com/new-products/current-sensor/>

I have had good luck with other items from Modern Device, but I have not =
played with this one.

It can be purchased here: =
https://moderndevice.com/product/current-sensor/ =
<https://moderndevice.com/product/current-sensor/>
for $18.

Not responsive to your query, but something I thought you might also =
find of interest:
