There is at least one cooking thermometer setup that I know could work with Hubitat (FireBoard) because I have been working on a driver that connects to their cloud API with a very patient community member that has one. It seems to be working fairly well now I guess, but since it is a single person (and single unit, and they have added 2 more to their lineup) I have not published it yet.
Getting the temperature probe into the oven might be a bit of fun and checking the prices this is NOT something for the casual user.
Of course if you find something else WiFi (not Bluetooth) there is the CHANCE (slim) that the company would be willing to work with someone to write a driver if they do not already have a published API.
