Showing Total figure in mini-graph-card with multiple entities

Hi,

I’m trying to configure lovelace and mini-graph-card with 3 power inputs. I’ve got the graph to work but the main figure it displays is the first entity.

As you can see in the picture below the power usage is 8W where it’s actually 120W if you include the server room. I’d like to know if it’s possible to show the total figure?

My configuration is

align_state: center
animate: true
decimals: 1
entities:
  - entity: sensor.fish_tank_power
name: Fish Tank
  - sensor.server_power
  - sensor.tv_power
name: Power
show:
  extrema: false
  labels: true
type: 'custom:mini-graph-card'

Any help would be much appreciated.

I can’t help but you have a server room? I thought I was bad …
