Issues with Victron MQTT Data Flow to Node-RED (Serial Number Only)

That still didn’t work.
I’m doing this over a home WiFi network, tomorrow I’ll try an Ethernet connection from raspi straight to same WiFi satellite as CCGX.
Also do I need to add it as an installation in the VRM portal using it’s portal id?

What’s baffling me is that my Fronius inverter was showing up in the device list earlier, and nothing else. The fronius is offline now as it’s dark so I guess that’s why it’s disappeared? But can’t work out why the Quattro and BYD batteries aren’t showing up when they are showing on the CCGX.

Finally, in Node Red when I try and use a Victron node, say AC Load there is an error in the node configuration window “ There are no ac load services available. Please check that a ac load is connected or try a different node.
Or should I just be using the Victron “System” node? When I edit that it has Venus as the system and then underneath I can select the Measurement. It still doesn’t work though!
It worked once (battery SoC) and then stopped, now I just get either null or the id of the CCGX.

I’m a bit lost.
