Cooking a pork butt today at a setpoint of 225F. After a couple of hours I looked at the app on my phone to check temps. All good. Put the phone in my pocket and a few minutes later I received a notification that my setpoint of 250F was reached. Figured I accidentally changed the setpoint when I was putting the phone away. Changed it back to 225F and put the phone down. A few minutes later I got a notification that my smoker was heating up to my setpoint of 380F! I moved the slider back down to 225F and watched the app. The slider was moving up by itself. I kept sliding it back down to 225F, and it kept wanting to go higher. Finally it gave up and allowed me to keep the 225F setpoint. Not sure if this is an app issue, or a controller issue. I'm halfway through this cook and afraid to leave it unmonitored. Anyone experience this?
