whenever I leave the hoose
Canadian, eh?
I was thinking to install a “smart” power outlet for the very same purpose, but stoves don’t have exactly standard plugs ;)
Then again, we just moved to a flat with induction stove, where it’s not really a big deal.
I put a Shelly uno in mine on the wire that runs thru the control lock buzzer. I used it to turn on the exhaust fan, but you could also set up an alert.
If your range doesn’t have the buzzer, you could retrofit the switches with ones that have the contacts for it.
Tangentially, I often wonder if technology has increased paranoia.
I can imagine someone worried about people following them might notice a lot more ear pieces, or if the increased knowledge of them has made that kind of fear decrease.
Great, so you’re already halfway there! You may be right on the temp sensor and the gas detector would probably be spotty too. I was thinking you could glue some magnets to the knobs and use a hall effects sensor nearby to map their position, but that would take some tinkering and I personally haven’t done anything like that.
But you mentioned you already have a camera pointed at it, you could add Frigate to Home Assistant and use object detection to notify you about events such as ‘knob turned’ or ‘panel glowing’ for flame detection or even just have it compare snapshots every x minutes and notify you of any change at all. Then you still always have the camera for visual backup as well.
