Thanks for this very useful blueprint.
It used to work for me prior to delete and reinstall it.

Now the installation is working fine, but when I try to create an automation, I have the following error message 👍
"Message malformed: Missing input pre_actions"

Would you have any clue ?

not working for me, it says 'Message malformed: Missing input pre_actions'

A good solution has been shared on the Home Assistant community forum :
https://community.home-assistant.io/t/notify-or-do-something-when-an-appliance-like-a-dishwasher-or-washing-machine-finishes/254841/117?u=hollyfredd

I am unable to create an automation using this blueprint. It says "Message malformed: Missing input pre_actions" I do not know what this means.

Same here…

Added another threshold to detect if the Washing machine is turned Off (and thus empty) or still in standby. Here is my code:

off_threshold:
  name: Machine Off threshold
  description: Power threshold above which we assume the appliance is turned off.
  default: 1
  selector:
    number:
      min: 0.0
      max: 5.0
      unit_of_measurement: W
      mode: slider
      step: 0.1
off_hysteresis:
  name: Machine Off hysteresis
  description: Time duration the power measurement has to stay above the Machine Off threshold
    power threshold.
  default: 1
  selector:
    number:
      min: 0.25
      max: 60.0
      unit_of_measurement: min
      mode: slider
      step: 0.25

and another trigger and action:

trigger:
- platform: numeric_state
  entity_id: !input power_sensor
  for:
    minutes: !input starting_hysteresis
  above: !input starting_threshold
condition: []
action:
- choose: []
  default: !input pre_actions
- wait_for_trigger:
  - platform: numeric_state
    entity_id: !input power_sensor
    below: !input finishing_threshold
    for:
      minutes: !input finishing_hysteresis
- choose: []
  default: !input actions
- wait_for_trigger:
  - platform: numeric_state
    entity_id: !input power_sensor
    below: !input off_threshold
    for:
      minutes: !input off_hysteresis
- choose: []
  default: !input off_actions

I am unable to create an automation using this blueprint. It says "Message malformed: Missing input pre_actions" I do not know what this means.

Same here

For those getting, 'Message malformed: Missing input pre_actions', add a wait time of 1 second into, 'Actions when starting threshhold is crossed' section at the bottom and it'll be saveable.

Thank you to the author of this plugin - it is very useful.

PS, Threshold has been spelt incorrectly :)

I was also struggling with the error message Message malformed: Missing input pre_actions.
You have to define a pre-action. If you do not need one, you can add just a 1s delay like @Steeveeveeve mentioned.
Here is my yaml file which you can copy and paste into the yaml editor.
