Ok, battling a bit with Node Red I think,

I'm getting payloads/values via MQTT from the Venus, and have been ale to ingest this into NodeRed, for now I'm just sending them onto OpenEnergyMonitor but what seems to get that side is a JSON message of {"value":some value}

how can I  split this that just the "some value" is extracted

Sure you already have an answer, but just in case here is what I do:

I use the json parser node to convert to a js object, then a change node to 'move" msg.payload.value to msg.payload

As an example
