Get prices in Node-red directly out the Cerbo GX

I cannot retrieve the dynamic prices directly from the Cerbo GX. I have tried using the MQTT node, the HTTP request node, and the Dynamic ESS and ESS Control nodes in Node-RED, but none of them seem to return the dynamic price data. Is it only possible to obtain these prices via the VRM API node?

I (finally) managed to get dynamic prices by following the steps from Dirk-Jan Faber (see below), but I like to get them directly out the system.

My configuration is a mulitplus II, cerbo GX an 16kWh battery. The system is set to Dynamic ESS,.

For a standard system that is correct. The Cerbo GX (VenusOS) is pricing agnostic. Only the scheduler, or your own code/flow, knows and acts on pricing data. They can be obtained from VRM via VRM API or other sources such as your energy supplier.

Thanks Jan, that saves me some further searching!
