Understanding sum of flows

[mdoliver]

Hi,

I'm trying to understand how the sum of flows work for certain bubbles (in my case the solar generation bubble). I have a setup which is working absolutely fine until excess power starts flowing back to the grid.

My issue: The amount of excess flow to the grid is being added back onto the solar generation bubble.

Flow as I understand it (see screenshot):

• 7800W generated by solar, sent to house
• House consumes 951W, sends 3.3Kw to appliance 1
• Remaining 3.51Kw sent back to grid
• 3.51Kw exported to grid is added back on to solar generation bubble (11.3Kw)

Here's my setup:

  - type: custom:tesla-style-solar-power-card
    name: Solar Flow
    show_w_not_kw: 0
    threshold_in_k: null
    change_house_bubble_color_with_flow: 1
    energy_flow_diagramm: null
    energy_flow_diagramm_line_factor: 2

    appliance2_icon: mdi:car-sports

Any help would be greatly appreciated!

The card expects the flows it gets fed to be independent from each other. You are using the same sensors everywhere. You need to divide those sensors and use them as sensor templates. My configuration:
