Two things about the new Lutron connect app:
1) when entering a password on the iPhone app, you have to press "done" to hide the keyboard then sign in button. Pressing "go" on the keyboard causes a wrong password error. Probably because the last character of the password doesn't register. My customer and I are very tech savvy and we were going nuts trying to figure out why he could not log in. Should be a pretty easy fix on your end hopefully.
2) give end user on iPhone a GUI choice. Three of my customers who used to use Home+ have complained about the new GUI. I have to agree it requires quite a bit of end user configuration to make the first screen usable. If the end user could choose the GUI used it would help. Or if home+ could support the bridge for no additional charge access it would be better.
