Funny you should ask...the main problem we have is ignoring/not noticing it and leaving a burner on after we're done cooking. 
I have the automation set up to make the LED strip brighter during the day and reduce the level in the late afternoon/evening so it's not annoying at all. Has never bothered us, and actually sort of looks cool when it comes on as the cooktop or toaster oven are turned on. We get a fair amount of "Oh cool, what's that?!" from friends and family.
Details are here, useful topic to read through for other approaches as well. My approach is very cooktop-specific, likely would not work on very many setups.
The toaster oven is on a power reporting plug.
