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?

do you have a gas meter? surely it would be simpler to capture the operation of the meter either electronically if it’s a smart meter or optically if it has a moving part or dial?
Even if your heating is gas it should be possible to disaggregate that usage by measuring the consumption over a minute or so.
