I can confirm that SignalK with embedded NodeRed (signalk-node-red package) provides access to both SignalK nodes as well as Victron nodes (via @victronenergy/node-red-contrib-victron).
I have moved all my flows to SignalK’s NodeRed and have now disabled Cerbo’s NodeRed.
NR and NR dashboard are also accesible via VRM SignalK proxy.
