I'm that guy... who chimes in whenever someone mentions a temperature controller. I've learned the hard way that some kinds of controls such as solid state relays can fail or get stuck in the "on" state, leaving you with thermal runaway. Also, software and firmware have to be considered as points of failure.

That's a good point, I'll take that in mind. Maybe I'll add another layer of protection with a second controller and relay that would only work as a timeout or heating overrun protection. It's still better than the previous situation when I would just forget the crockpot running.
