It's not very useful. But, I can start a program from an app which is a lot easier than understanding all the little logos on the unit. Plus I have more flexibility to tweak it, like be faster or gentler or schedule it to cheaper electricity hours all much more easily and intuitively than in the panel.

Also timer, remote start, and letting me know when it's done are something I might use once in a blue moon.

Can I live without it, hell yes, but is it a totally useless gimmick... Well 50/50.
