LED warning lights and detection for stoves

Stove is hot, the big red LED sign blinks HOT. Might as well put it on the oven part as well, and for the blind, a similar system that makes a sizzling noise until the oven/stove cools down. Many ways to set up the LED system, could also just blink, or even show red when it's hot and green when it's cool. X2 idea for universal access!
