I have a camera aimed at my stove so I can check if I accidentally left the stove on. It never happens but it does give me peace of mind whenever I leave the hoose and get paranoid.
Maybe someone mentioned this, but I’m sure there’s a million ways to tackle this task through Home Assistant and a cheap sensor. That way you get passive notifications instead of having to actively check.
Come up with a way such that i dont have to take apart the stove and im listening.
Definitely don’t have to take anything apart. If you can’t use a smart plug on the outlet, A zigbee temperature sensor mounted above or near the range would do the trick. There’s also methane/gas detectors.
If you’ve never used Home Assistant, it’s super easy to get going and you can automate nearly everything, so getting phone notifications or persistent temp reminders would be a breeze. Let me know if you have questions about that part. I’m by no means an expert, but I’ve been slowly automating everything in my house and it’s been great.
I’m using home assistant for the photos right now. The problem with a temp sensor is that it could stay hot after a while even if the stove is off.

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.
