I was wondering if someone has done something similar:

I want to detect if one of the kitchen burners have been running for a long time. Gas sensors won’t work because the fires are running.

I was thinking that a solution could be to have a wifi-enabled thermostat that sends the temperature to home assistant and if it is above > X for Y minutes, send an alarm/email/notification. The sensor could be hidden below the burners and connected via a cable to measure the temperature.

Does this make sense? Does anybody have some idea how to implement this (maybe using a ESP8266)?

Is there other alternative?

    If it’s a gas burner then it produces CO2 as it operates, right? You could probably mount an ESP32 kit with a CO2 sensor (SGP30) and passive infrared receiver (AM312) over the range to monitor the CO2 level, and also whether anyone is standing at the stove. I didn’t check to see whether these modules were supported directly by esphome, but I’m sure the project either has a compatible module, or you could adapt something from the project to support these modules.

    You could then program HA to alert if long term CO2 is elevated and no motion is detected at the range for some time.

    Just an idea. I might try tinkering with something similar this weekend. I don’t have the gas sensor, but I’ve been looking for an excuse to order one
