wow, so I have a cheap temperature-controlled kettle, and I put it on while making food as I always do, but then suddenly it started continuously beeping at me in a smoke detector cadence, very clearly trying to tell me that something was wrong
I looked at the live temperature display (which yes, is real), the temperature had been rising more or less as it does normally, except... the water wasn't really approaching boiling, it was barely heating up, definitely nowhere near the temperature the sensor was measuring
and it somehow... detected this?? it somehow knew that the temperature it was measuring with the sensor didn't match the 'true' water temperature??? even though the temperature curve it saw was normal????
how on earth did it know that
