errors on lines 63 and 68 automation wont save properly if you dont need or want to use the starting action and doesnt seem to work very reliably at all when trying to work around these issues, cant recomend this unless the owner comes and updates it for 2022

As stated above.
My previously compltly other approach is working without any issue (at least with my sonoff pow r2's) on 3x devices.

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 :

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.

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

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.
