blueprint:
  name: Appliance Power Monitor
  description: Monitors the activity of a home appliance based on the power (W) it consumes and triggers actions based on start, running, and stop events. You can use the variables {{ elapsed_time }}, {{ energy_used }}, and {{ event_type }} in all the steps (start, running, and stop).
