I'd be interested in a paired device to interrupt the energy source to the stove. If danger is imminent and the operator hasn't responded in a certain timeframe, a connected valve would turn the gas supply off or a switch would trigger the electricity to turn off.
Growing up we had a sensor in the oven go out, causing the cookies to catch on fire inside the oven. We also had a control board on a Whirlpool dishwasher start smoking ~15 years ago. There was a class action lawsuit against Whirlpool, but we didn't have any documentation that showed the model and serial number of the unit, so we couldn't get the typical "$20 credit for your next appliance purchase" or whatever the compensation was.
In both cases, flipping the electricity off at the breaker prevented further damage.
