My child system not showing consumption in parent graph ?.
Any data uploaded to the parent directly will overwrite any data aggregated from the children.
You will need another system and split out the consumption uploaded to the parent to this new child.
Parent - Generation only
Child A - Consumption 1
Child B - Consumption 2
The parent will now have Consumption 1+Consumtion 2+Generation
the tariffs are not recorded to the parent .i have this as follows,
Parent - Generation
Child A - consumption
Child B - consumption
the 2 childs have different tariffs rates .
The parent always uses its own tariffs, the ability to aggregate child tariffs is not available should be posted as a separate idea topic.
