When I subscribe to Venus' MQTT topics I saw the inverter appearing under topics like
N/<Portal ID>/vebus/276/... or
N/<Portal ID>/vebus/275/...
Full example:
N/<Portal ID>/vebus/275/Devices/0/Ac/Out/P
{ "value": 12 }
What do those numbers mean? I couldn't find the documentation for that.
Are the numbers fixed and the same for all models or might they change over time?
