My wife decided on new granite and cook top, and displaced an older Thermador top.  Very nice, easy to clean design.  Very attractive when installed.  The online (Smarthings) feature doesn't do much but indicate off and on.  So I am not sure if this feature is needed.  Unless of course, you check if you left to burner on for some reason.  Price similar to other top of the line cook tops..  Overall, my wife is happy, so I am happy.
