Help understanding consumption chart

Here’s a screencap of my dishwasher’s power consumption while running. I’m trying to create a sensor to detect when it’s running. What is represented by the lighter blue region? Mousing-over reads “max”, but I was watching the actual value of the sensor and it wasn’t that high. Is that a historical max over some period? Looks like I should be able to watch for that big area at the end of the cycle - the drop-off of the curve mapped well to when the washer finished drying.

This is the cycle of my dishwasher:

I set input_boolean.dishwasher_run to on when power draw goes above 5W for 15s and I receive a notification when the power draw is below 1.9W for 5min, but only if the input_boolean.dishwasher_run is actually set to on at the time.

- alias: D/W Set On
  description: ''
  trigger:
  - platform: numeric_state
    entity_id: sensor.sonoff_s31_01_power
    above: 5
    for:
      seconds: 15
  condition:
  - condition: state
    entity_id: input_boolean.dishwasher_run
    state: 'off'
  action:
  - service: input_boolean.turn_on
    entity_id: input_boolean.dishwasher_run
- alias: D/W Set Off
  description: ''
  trigger:
  - platform: numeric_state
    entity_id: sensor.sonoff_s31_01_power
    below: 1.9
    for:
      minutes: 5
  condition:
  - condition: state
    entity_id: input_boolean.dishwasher_run
    state: 'on'
  action:
  - service: input_boolean.turn_off
    entity_id: input_boolean.dishwasher_run

Once the notification has been sent the input_boolean.dishwasher_run is set to off

I don’t really put much enery into interpreting the kind of history chart you’re showing - other than the dark blue line it’s of no use for me :confused:

P.S.:
Please not that there might be some legacy terminology in there, I’ve been using this setup for a few years by now :slight_smile:

After some searching with different terms, I came across this thread. The blue area is described as a 5 minute max/min, with the blue line being the 5 minute mean. I’m working on recreating that with a statistics sensor.
