My Fronius smart meter is in consumption mode (1) rather than feed in (0). There is a thread with a workaround for those with consumption mode meters, but it’s not easy to understand. It would be amazing if the Fronius intergration had the option to indicate which mode is in use so the data in the energy tab is correct.
Hi 
!
You can see the current mode in the device view of your meter.
Other than that we did our best to document this https://www.home-assistant.io/integrations/fronius/#energy-dashboard
If you can add something to further clarify the documentation, that would be very welcome!
