Smartshunt dc solar power monitoring

I have a dc solar pump that is conected directly to my solar panels (via a switch)

My bleusolar mppt measures what my 12v battery is doing


But I would like to measures the current and power usage of my dc 24-72v pump


So I thought smart shunt conected between the negative solar input of my mppt and my pump


But as far as I can see it will always show up as a batery load if I set my shunt to dc power meter ?


I would love to connect the shunt to my gx divice


Reworded:

I have 1 solar pannel

1 bleusolar 75/10 mppt

1 solar pump (build in mppt) (parallel to the mppt input)

1 gx device (raspberry pi)

1 battery


Would a shunt in dc power meter work ?

Can I create 2 dc systems in a single gx device?
