A:AnswerYes you can. You can do this when you put the thermometer in the meat, then choose the temperature you need to use but inputting it on your phone.
A:AnswerShouldn’t be a problem. I believe I used mine for up to 8 hours on a brisket and also pork shoulder. Mine stopped connecting to thermometer after 3 cooking sessions. Trouble shooting help from Yummly didn’t fix the connection problem. Don’t waste your money on this device.
A:AnswerYep, it also tells your your oven temps as it also reads ambient temp in addition to meat temp. Temps a re little off though so definitely follow up with a good probe instant read thermometer for poultry and pork.
