I have been looking for such a device a couple of weeks now. Apparently yearly, about 150,000 fires start due to unattended cooking resulting in ~$1 Billion in damages. We are doing a new construction and essentially I am looking for a device that:
can tell me if the gas cooktop stove is being used (there is a flow) and allow me to cut off the flow remotely (ideally works with ST).
Take it one step further and in case the (smoke) alarm sound is going, also cut off the flow. And in case of an earthquake (rapid movement of the device), also cut off the flow.
Anyone know of such a device? It’s probably too much to ask for it to be ST compatible so I will take anything that is out there that has the first feature.
