Is it possible in Victron's world to measure DC 12V consumers individually from each other, as you know it from PICO?
If possible, what should be used to get the individual measurements?
See the image as an example: Lights, refrigerator, etc.

How to measure DC 12V consumer individually
The smart shunts have an option for generic loads. But imagine that'll be awfully expensive/overkill for the consumption those loads you describe will be using.
The other option is using some other power monitor and forwarding the data to the gx device. And setting up virtual "smart shunts" using dummy dbus services.

I imagine shelly pm devices might be a way to do this for cheaper. Essentially using a shelly pm but spoofing it into a smart shunt set as a generic load.
Hmm.. I found this project, but it's only for the Shelly Plus 1PM. And as I understand, this one does not run on 12VDC systems.

Is it possible to make an equal system for Shelly 1 with support for 12 and 24VDC?
I'm not the biggest scripter.
Apologies you're correct.
What you really want is a smart shunt but you dont need one that's very large/expensive like the victron one. There's the arduino route but imagine that'll be a fair bit of effort.
EDIT i tried doing some further research to see if shelly EM included a hall effect sensor in it's ct clamp to measure DC current but dont think it does. Maybe a shelly uni?
Personally, I distribute several of TP-Link's HS110 SmartPlugs, dedicating them to high-power appliances, and then use the Kasa phone app to look at the energy consumption. Sadly, that energy data cannot be exported via the programming API, however.
I will note that users like myself have been pestering them and it looks like they're created this. It looks like it brings up a simple website and this JavaScript appears to fetch in the energy consumption data, among other things.
If one were clever, one could go to school on that code and build a Dbus shunt service for it as a virtual smart shunt.
