Thanks for your blueprint, it fits my use case pretty well. However, I think I noticed a small mistake.

The description asks to limit the sum helper to 7, but in my automation this fails because it tries to set a much higher value. It seems to work without the limit.

@Zaunei I messed up the description of the helpers. I updated the code on github.

Let me know if you have any other additions.

The logic is fairly simple:

The automation adds 1 to the count helper until it reaches 6. At 7 it resets the helper.
When count is 6 it calculates the avarage of the sum helper (which added 6 readings of the wattage) to check if the avarage is below the threshold. If below the threshold it continues the rest of the automation
