Is there a way to see (and use in flows) the current injection of electricity into the grid with the Homey Energy Dongle?

Yes, could depend on a brand and type DSMR specification but I guess most do.

Pls note the Current is unsinged and rounded to Ampere afaik by the specification.

Better use the Power fe fase. That is more granular then the Current and also shows the direction.

Thanks for the answer but I specifically want to know on a given moment what my exact injection into the grid is. There is a ‘current’ power value, but this is import. Will this value become negative when power is being injected? My Homey Dongle is brand new so will see it tomorrow anyway 😉

Looking at Power you can see the injection and values more precisely.
