It is very convenient to be able to preheat the oven from anywhere I am as long as I have my phone. If I am upstairs and forgot to turn on the oven, I can do it via the app on my phone. I can check on what is cooking no matter where I am as well, via the oven camera which can be accessed by the phone app. HUGE leap of improvement over my last oven which was only 6 years old. Technology is a marvel!
