Can you or someone explain to me why you need or want Bluetooth on a sous vide circulator? You already have to be physically next to it put your food into the water bath. It makes no sense to pull out your phone and launch an app to turn it on and set the temp when you're already physically standing right next to it, and I've never heard of any sous vide recipes that require you to change the water temp partway through cooking, so there's no need to change the temperature remotely. The only thing I could possibly see wanting a Bluetooth app for is monitoring the water temperature in case it's gone wonky, but in the 5+ years I've had my Anova, it's always been flawless.
