Steps to create a conditional rule:

  11. Click on Define Expression element and select New Condition
  12. Click on Select capability for Action Condition and select whatever device type provides you with a power reading (e.g., Power meters?)
  13. Click on the selected device type and select a specific device (I'll call it "Car Charger Plug" for this example)
  14. Click on Comparison and select <
  15. Enter a Power level value, such as 1300
  16. Click on Done with IF expression THEN
  17. Click on END-IF at the bottom of the Actions table
  18. Click on Done with Actions
  19. Click on Update Rule

To complete your Rule, you will need to:

  1. Define a Trigger, such as your presence sensor becoming true (optionally add "and stays that way for X minutes")
  2. Add a Delay action before the IF-THEN action (20 minutes, for example, to give you time to plug in)
  3. Insert a Notification action between the IF-THEN action and the END-IF action (to warn you that you got home and 20 minutes passed and car charger power is not being drawn).

Several other contributors posted examples of more sophisticated rules. Once you create your own basic rule, you might want to look at those examples to see if you can improve your rule.
