hello @oldmcg this is a great recommendation for a feature enhancement and I have already sent it over to the dev team. In the interim, some customers have backed into an amperage number by using amps x volts to get watts and then using that as a notification trigger and or a power figure to look for.
20A breaker at 120v set a notification to alert if this circuit is equal to or greater than 2,400 watts for 1 second.
