This is pretty much the same documentation I studied earlier - see links in my original post.
Is it possible to get the required info by using the zwave channels - I’m very unsure.
Do I import or export energy “right now” = does my solarplant generate more power than I currently consume? No idea how to find that out from the documentation…
What is the power (Watts) accociated to it
This measurement I probably get with “Electric meter (watts)”
Other question:
Why 5 endpoints? “Total” + “Phase 1,2,3” would be 4 endpoints ?
Maybe endpoints 1,2,3 are not meant to be mapped to the phases?
That is what we have I think. The root endpoint is normally only providing heritage support, so you will have the root, then phase 1/2/3, and total - probably
No - if you don’t know, then we won’t know as you have the device. If it’s not documented, then we can only guess - like you. Or you do a test and load up the phases individually to see what is reported.
OpenHab2 doesn’t support the rate type Export values. Due to this, you will not see the kwh(export) values, which increments, when a photovoltaic system is connected. You will only see negative power consumption (negative W values).
For now, the platforms and gateways that do support kwh(export) and w(export) are: ioBroker, zwavejs2mqtt, Toon gateway.
• Do I import or export energy “right now” = does my solarplant generate more power than I currently consume?
You can see this as the power that is produced is reported as negative W
• What is the total power (Watts) accociated to it This measurement I probably get with “Electric meter (watts)”
generaly you should get 4 (5 the one without the number is the copy of 1) readings under number 1 it will be the total of the W, the W from 2 - 4 is divided by Lines.
• Accumulated energy import / export (kWh) until “now”
Not possible because OpenHab don’t support this value.
• What does “Electric meter (kWh)” report? Netted import/export?
Right now only the import.

They are pointing to limitations in openHAB.
Nothing that I can verify, judge…
As a contribution to this discussion I lacked reporting of “import” total energy. Qubino support gave me this info:
"Every z-wave device consists of endpoints. The 3 phase smart meter has 5 endpoints, by default. The root endpoint and endpoint1 both map to the same functionality, that is why the values are the same. In a nutshell: the root endpoint and endpoint1 have the same values (total power consumption, the accumulated energy), whereas endpoint 2,3,4 map to the three phases 1,2,3. Currently, z-wave.me only shows the “consumed” (rate Type Import) values, whereas it doesn’t display the “produced” (rate Type Export) values. We’ve notified z-wave.me about this a few weeks ago. They said that it will be added to their queue of features, which will be added.
For now there are only three gateway, platforms that can receive and show the import and the export (produced power) on the market for now that are: : ioBroker, zwavejs2mqtt, Toon gateway.
The measures are sent in the reports
COMMAND_CLASS_METER 0x32
METER_REPORT 0x02
Rate Type
"
I have not investigated what the technical part means, but this might answer a few of your questions and provide some technical details to the z-wave binding issue.
There is one difference though and that is that I only see “exported” kWh and kAVh, but I’m only interested in “imported”… In the beginning of my support talk with Qubino, they provided me with their latest firmware and after updating to that I don’t have any other issues. Only the Z-wave binding support (as I understood it) is missing.
