I used a raspberry pi (small cheap computer) and installed the Victron software rather than purchasing the expensive cerbo. It was a bit of a pain to install but once I got it running on the raspberry it was just a matter of buying some ve.direct to usb cords and plugging each component (solar controller, inverter, smartshunt, etc) into the raspberry pi. Now I can see all my system info from wherever I want (assuming my hotspot in the camper is working… different issue tho).

I think if you buy a cerbo it’s much more of a plug and play. No messing around installing an OS on a raspberry pi. But, much more expensive too.
