| type | `string` | **required** | `custom:power-flow-card`. |
| entities | `object` | **required** | One or more sensor entities, see [entities object](#entities-object) for additional entity options. |
| kw_decimals | `number` | 1 | Number of decimals rounded to when kilowatts are displayed |
| min_flow_rate | `number` | .75 | Represents the fastest amount of time in seconds for a flow dot to travel from one end to the other, see [flow formula](#flow-formula). |
| max_flow_rate | `number` | 6 | Represents the slowest amount of time in seconds for a flow dot to travel from one end to the other, see [flow formula](#flow-formula). |
| watt_threshold | `number` | 0 | The number of watts to display before converting to and displaying kilowatts. Setting of 0 will always display in kilowatts. |
