I have the Venus Pi, Smart Shunt 500 and the Smartsolar MPPT 100/30. All updated to the latest firmware and connected with the Ve. Connect USB cable.
When I plugged the solar into the Venus I could see it. Later on it has disappered. I think it happened after reBoot or firmware update. The MPPT has not the solarpanels connected yet, but is connected in the battery side.
The Smart Shunt is working correct
