Lutron Homeworks Qs Processor Not Responding

>> What Lutron system are you working on? <<

Updated about 2 weeks ago.

>> Are you trying to connect the app to the local wifi, or use remote access? <<

As mentioned in my original post, I'm using both local Wi-Fi and remote access. It failed under both conditions.

>> Have you ensured all devices are in the same network as the Lutron processor/repeater? <<

Yes.

>> please go to the system page and click on the 'i' and choose the option to "email feedback". <<

I cannot do this. I do not do e-mail on my iPhone. I searched high and low, but could not find an e-mail address that I could use from my Macintosh.

I did find a solution. All of our devices were using iOS 7.1.2. The latest version of the Lutron app requires iOS 8.0 or later. SHOCKINGLY, the app does not check for this when launched! It simply spits out, "Cannot Connect to the System". If the software was properly written, it would report this issue to the user.

Thank you for helping.

    iPhone Lutron Home Control+ app has stopped working AGAIN.

    Once again our Lutron iPhone / iPad apps (Lutron Home Control+) has stopped working.

    This system has about 8 iOS devices. All are using the latest iOS as of 1-1-15. Strangely, one the 8 devices (iPhone 6) being used, and only one continues to work perfectly. All of the other iPhones and iPads fail when trying to “Download System Configuration”.

    The one working iPhone 6 is running Lutron Home Control+ 8.0.1, other nonworking devices have 8.0.1 or 8.1.

    Steps taken so far to fix:

    1) Update iOS and all applications to latest version.

    2) Turn devices on and off.

    3) Uninstall Lutron program and reinstall. Program does find the Lutron system but cannot “Download System Configuration” and then it fails.

    4) Power cycle router.

    This project also has a Control4 system. The Control4 iPhone App successfully controls all the Lutron devices using ALL iPhones and iPads, but the Lutron app WILL NOT control Lutron.

    Just thinking out loud:

    Run a network check for duplicate IP address
    I use "Fing"

    more thinking out loud-

    Does each iphone app user have their own username and password to login? I usually make a habit of giving each user their own username and password, and then set up unique usernames and passwords for me and for any 3rd-party devices like control 4.
    While the auto-discovery feature in the app may not REQUIRE you to have a separate username and password for each app user, it may help head off problems like this. I would also suggest setting up a static IP for the Lutron processor(s) involved BEFORE creating new usernames and passwords for each LHC app user. Each user should then delete the system and manually add the system. The lutron system can't handle that many simultaneous requests, so I'd advise you update each device one-at-a-time and probably close the app after a successful install on one device so that the next device isn't competing for a connection.

    No. System has been working properly for several months with all iPhones / iPads having same username and password.


    That's a pretty serious “hassle factor” that I'm not going to deal with. I would remove Lutron entirely before going to that extreme method.


    All of the Control4 devices share the same username and password, (a different username and password than for Lutron of course). ZERO problems with Control4.


    This was done from the beginning.

    Simultaneous requests have never been made. Only one user is using the system at any time.

    Reasonably sure we have been operating like this. One of the major negatives of iOS is the inability to revert to previous WORKING versions. Some manufacturers try to work around this limitation by having earlier versions of their apps on the Apple App Store.


    Thank you for your assistance. Clearly, Lutron Home Control+ is a highly delicate and fragile interface. This project has other home automation aspects. The Lutron system has been the most difficult to make function consistently.

    We were able to make the system work by power cycling the Cisco ethernet switch. Power cycling the router and the Lutron processor did not help.

    This sounds like no fun indeed.

    Yes I like that idea too.

    I'd be concerned that you have a networking issue. I have experienced trouble with iOS apps not doing what I expected but they have never been rectified by rebooting hardware. I hope you have good luck with iOS from here forward.

    Thanks. Should I learn something about our system in the future that might prove helpful to others, I will report back.

    I DO appreciate your assistance.

    If you suspect the LHC+ app, you could always try a third party app. But from you description it looks like you have a network issue, not an app issue.

    I use HomeSense app, works well for me, I especially like the widget for iOS8. I don't think it has iPad interface (yet?), so select 'iPhone Only' if you are using iPad.

    same problem

    I have exactly the same problem. Home + app on either Iphone or Android that was once working will no longer connect to, or even find, the RA2 system. I have tried all your solutions without success. No idea what to do next
