blueprint:
  name: Power Threshold Auto Switch Off
  description: Check total consumption and turn off the devices based on their priority. 
  domain: automation

  input:
    total_power:
      name: Total power (W)
      description: Select the sensor that represent the sum of all the switches' consumption in W. To find out how to create one, visit the github page.
      selector:

    threshold:
      name: Maximum Threshold in W
      description: Enter the threshold in W which, if exceeded, will trigger the cascade shutdown event of the switches (only those turned on)
      default: 100

    check_delay:
      name: Check delay (seconds)
      description: Enter the delay in seconds that must pass after the first switch turns off. If after x seconds the consumption is again higher than the threshold, repeat the shutdown with the second switch and so on.
      default: 5
