I'm sure there are. I'm just saying that if you have a well regulated environment controlled by a PID, having an additional widget measure ambient temperature isn't going to tell you anything new. It'd be like having an extra thermometer reading the temperature of a sous vide bath when there's already a thermometer measuring that temperature in the circulator.
The Breville ovens have excellent temperature control. If I set them to 350F, I don't know that I'd want or need an additional gizmo to tell me that the oven is set to 350F. Maybe some people would find that information worth paying for, but a smart thermometer is of diminished utility in a smart oven (or on a Control Freak, or for use with a circulator).
Pellet grills are larger and more prone to having hotter and colder zones, so that's kind of a different ballgame. But I take your point... different strokes for different folks. If people have the Joule Oven and also have a Combustion probe, it'd be cool to use them together. But I think the number of people who would buy Chris Young's thermometer just to use with the Joule Oven is quite small.
