I did a search there on temperature alarm and there is one for $27 on sale that will alarm if the temperature goes too high. Or, you can set it to alarm if the temperature goes too low. For room temp, it can be set for both a high and low temp alarm, but not with the probe.
I have a Ranco temperature controller. Maybe that is what you were referring to. It's expensive ($70 or so), but it would shut things down if temps got too hot. It could also turn on an auxiliary heater if the temp dipped (it's also only high or low, not both), but you could do the same with a second heater set a few degrees below the norm.
The cheaper alarm is sort of what I was thinking of. I think I could build one for less, but it would not be digital and would take some effort to set it.
