On live view of the children I can see my power of the three Inverters separately.
On the parents live view it is not working. It shows too much up and down errors.
need more information. can you show how you have setup the parents and child?
have a read through this

The system “Roth_Rechts” is being updated every 15 minutes while the other two is every 5 minutes.
The dips in the green power line is due to the missing 10 minutes. There is no data from Roth_Rechts to add to the parent during these intervals and the summed power appears to be lower.
To get a smoother line all child systems should have the same update interval.
