Temperature sensor (again?)

Any news on a temperature sensor? I would think you would be able to have it report the current temperature at some preselected interval (not continuously). I have lots of applications — turn on heat lamps, or small heaters when temperature is close to freezing, turn on fans when temperature gets above threshold and so on.

Extra credit — have remote probe so could use in oven or freezer and have the wireless unit outside the enclosure so it can communicate with the bridge.
