For anything to adust the temp it needs some type of thermocouple - a temperature sensor, and the electronic stuff that goes with it. And it costs.
Sounds like a great idea. But I would have no idea how to set such a thing.
But if they were cheaply available, maybe we would learn.
Take care and Giod bless.
