Can someone here please share a working example of a virtual PV device?
I have setup two now, but I don’t know what the actual requirements are. For example. Do we need to set the /StatusCode and if so to what value.

This is my virtual PV inverter. I want to see the daily yield of my PV-Inverter instead of overall lifetime yield. It is measured by a Shelly 1PM Gen3 device.

]Hi Tom. You’re not using virtual devices are you? I might be wrong, but the nodes look different to what I have in v3.70
I do, and the flow above uses the “virtual device” node:
Node Red flows look different in the Node Red editor than here in the forum. The flow which I published above looks like that in Node Red:
Ah ok. I see. Sorry. Yeah that isn’t very helpful for this forum. But it does seem to work here, now, with a few hiccups. Like the most relevant paths when you click on the virtual device (TomsBKW in your flow example). It shows /Ac/Frequency — AC frequency in Hz. but I cannot find it in the list of paths under custom control nodes. Must be a documentations error.
One other thing. The solar is connected on AC-IN when the Kraus & Naimer selector is on Netz, but at AC-OUT when that switch is turned onto Not-Strom. That was an error in my side. I had the /Position set to 1 and had to change that to 0 to make it work. Aka not to make PV show up un Essential Loads.
