Binary sensor not properly shown

I want to graph two different binary sensors, one for a door lock sensor, the other for my heating systeem

Now, using this code

type: 'custom:mini-graph-card'
entities:
  - entity: binary_sensor.carajito_active
    name: State
    color: red
name: Heating
hours_to_show: 24
points_per_hour: 4
aggregate_func: max
line_width: 2
smoothing: false
state_map:
  - value: 'off'
    label: Waiting
  - value: 'on'
    label: Heating

I’m just getting a flat line, even though as you can see the sensor assumes on/off values properly

---

For the door sensor is even weirder, as I’m getting an inverse graph:

type: 'custom:mini-graph-card'
entities:
  - entity: binary_sensor.tuya_door_sensor
name: Hold the door!
icon: 'mdi:door-closed'
hours_to_show: 24
points_per_hour: 4
update_interval: 30
aggregate_func: max
line_width: 2
smoothing: false
state_map:
  - value: 'on'
    label: Mooooar
  - value: 'off'
    label: Bravo Hodor!

So the values are exactly the opposite value.

Any hint?

I did it like this and works. The binary_sensor.isNight provides true and false, but if i use state_map with this, it won’t work. It seems “off” and “on” does the trick, but don’t ask me why

type: 'custom:mini-graph-card'
icon: 'mdi:thought-bubble'
name: Feinstaubbelastung
hours_to_show: 24
points_per_hour: 2
update_interval: 1
cache: false
hour24: true
entities:
  - entity: sensor.feinstaubsensor_pm25
    name: PM2.5
    color: orange
  - entity: sensor.feinstaubsensor_pm10
    name: PM10
  - entity: binary_sensor.isNight
    name: Nighttime
    color: grey
    show_line: false
    show_points: false
    show_legend: false
    y_axis: secondary
state_map:
  - value: 'off'
    label: Day
  - value: 'on'
    label: Night
show:
  labels_secondary: false

Thanks for the info. I reckoned there was a caching issue, because after a day or so there would be at least “wrong” results meaning the graph was inverted or something similar.

No, the issue didn’t resolve itself. My solution was to create a template value sensor in HA which translates the binary “on”/“off” or whatever to numeric 0/1 and use this numeric value instead on the secondary axis.

This gives me the desired result

The gray shadow in the background shows whether the the thermostat is in “eco” or “comfort” mode and the orange line shows the current temperature of the room.
