I don't understand the point. The only time I can see Wi-fi being useful for sous vide is if you were to buy a Mellow, which includes a built-in chiller so that your food stays cold until you want to cook it:

That way, if you're going to be home at 5, you could set your steak to cook for 2 hours starting at 3pm. Then just get home, sear, and voila - dinner. Doesn't make much sense to me on the Anova, which lacks a chiller. Maybe with frozen meat & ice cubes? Although I wouldn't risk it...
