There is a Chinese pressure cooker with gas stove on the market. This swiches off the gas when cooking is over. The technology is straightforward enough. The issues relate to safety, Failsafe operation, power pack, sensors and such. A new latching type solenoid valve has been patented in the US, which consumes negligible power , which has been used for some prototypes of the kind of 'smart stove' suggested.
An interestuing variant has used an ingenious thermopile to generate the power from the stove itself. Thus eliminating the need for a power source. Maybe the stuff will hit the market soon.
