Just did an overnight butt and now it’s sitting in the cooler resting. Everything went well and the 590 was rock steady with the temps. It did overshoot whenever I opened the lid as expected but then settled back down quickly. The app is pretty good but was a bit annoying with all the warnings while I’m trying to sleep. For instance, I set the probe alarm at 160 so I can wrap the butt. When it got close to that temp, I would get all these msgs about being close to temp. I just want to know when it’s at temp since I was sleeping and don’t need all the msgs about being close to temp. Other than that it was a lot easier using the 590 than the Kamado. I’ll see how the actual bbq turned out later tonight.
