### 1/5 — App not working anymore since iOS 11

*2017-12-30*

Since I moved to iOS 11, the app cannot complete the connection to the web server anymore and I can no longer use the Domotic system of my house. Can you please help?

### 1/5 — Version 1.5 crashes all the time.

*2013-06-23*

I had version 1.4 of this software on an iPhone 4 and it worked just fine.  I made the mistake of updating to 1.5 and now the software crashes constantly.  I've deleted the app and reinstalled it numerous times and the software will only work the immediately after I download it.  As soon as I close the app and try to open it up again, it crashes rendering my home automation practically useless.  I can't revert back to the older version because I don't have a backed up version of the older version.  I really hope that Vimar fixes this problem asap!

### 1/5 — It doesn't work

*2012-07-01*

I press the buttons, but there is no action...
