Missing Solar production in Energy Distribution graph

Configuration
1

Hello,

this is my Energy dashboard and as you can see there are no data in Energy Distribution graph about Solar contribution. Instead I have 2 graphs, but I’d like to have combined one as It is presented in documentation where the graph includes hourly Solar statistic, see bottom of my post.

my simple graph config is
type: energy-usage-graph

entity config to collect stats about production data is:

    sensor.pzem_nh10_solar_energy_today:
      last_reset: '1970-01-01T00:00:00+00:00'
      device_class: "energy"
      state_class: "total_increasing"

Graph with missing SOLAR part:

See here what I am expecting:

Please advise where is the problem. Thank you.

I will respond to my query. If return to grid entity is not defined in Energy dashboard configuration page, then solar contribution will not bee seen in energy-usage-graph. Simple like that. Hope it will help to some one.
