Data point not written in state field, when zero

[akloeckner]

I just discovered that datapoints with 0 value are not written into the state field, when hovering over the data point.

Example:

The state field reads 18,9%. It should read 0%. The value 18.9 is the curent state of the primary entity (the actual temperature). And % is the unit of the data point currently hovered above (the opening of the thermostate valve).

Configuration for reference:

type: custom:mini-graph-card
entities:
  - entity: climate.eingang_thermostat
    attribute: current_temperature
    unit: °C
  - entity: climate.eingang_thermostat
    attribute: temperature
    unit: °C
  - entity: sensor.eingang_thermostat_level
    y_axis: secondary
    unit: '%'
hours_to_show: 24
points_per_hour: 2
aggregate_func: avg
hour24: true
decimals: 1
smoothing: true

  labels_secondary: true
  legend: false
