i have a Grid Power Meter from which i get data via REST (JSON) within Node-RED.
(Node-RED is running on Cerbo GX/Venus OS Large)
Is there a possibility to make Grid Meter data available on DBus to use that data as “AC Input” ?
Already found this project for Shelly meters “dbus-shelly-3em-smartmeter” but i do not have a shelly and data is already here within Node-RED.

you should be able to send MQTT from NodeRed to the script linked.
I get data from SDM630 via modbus into HomeAssistant. I reformat the message in NudeRed and forward ti Cerbo/NodeRed where I forward to the linked script.
gave it first try to export grid power data from Node-RED context data to MQTT.
Will extend to also have Voltages and kWh later on.
currently my JSON looks like this (Power Total, L1,L2,L3)
{
“grid”: {
“power”: 2692,
“L1”: {
“power”: 941
},
“L2”: {
“power”: 1055
},
“L3”: {
“power”: 695
}
}
}
