grid service not created

[stundenblume]

This is a follow up from here.

• pvinverter is created as expected.
• no grid service created.
• current.logis empty.
• /data/dbus-opendtu/uninstall.sh and python3 /data/dbus-opendtu/dbus-opendtu.py gives no output.

[dsteinkopf]

python3 /data/dbus-opendtu/dbus-opendtu.py started from the command line starts python running the named script. So you should see some console output - at least an error or so. If not, then something is completely wrong. What EXACTLY are you doing?

I don't get any output.

If I interrupt the script with ctl+cI get:

please read: https://github.com/henne49/dbus-opendtu/blob/main/README.md#troubleshooting

You have to change Logging=ERROR to Logging=DEBUG to see more

[stundenblume]

Thanks for the hint.
I did everything on a fresh install.

Now it registered the grid service:

One thing that does not work probably is the representation and calculation in VRM portal.
If I do nothing the AC-IN is empty. Even if the representation in the remote console is correct.

After setting N/b827eb4961c3/system/0/Ac/ActiveIn/Source from null to 1 the representation works, but not the calculation.
Notice the leading N/. With W/ it's not possible to change the value. After a while it will be reset to null.

It's the same with the dbus-mqtt driver. The diagrams show always the same for "Solar" and "Consumption". "From/To Grid" is always zero.

[stundenblume]

Maybe it works as expected... I will report later this day.

[stundenblume]

Good morning,
your driver works.
Thank you very much!
The only thing that left be open:

• 3 phase support
• correct representation/calculation of "to Grid". But that is not directly related to your driver.
