We can access the device vi browser on HTTP 80 portWe are able to ping the device But, when we install the APP (Android or iOS) Home+ and try to connect via Smartphones is showing the following message'Was not possible to connect to the system Cancel, Inform issue, Try Again.The Lutron is detected automatically, we are able to ping Lutron from smartphone. We are abe to open the Lutron HTTP pageBut the app not work There is any compability issue with Ubiquits? Thanks.

Make sure you have multicast enabled on all routers, switches and access points. I have installed systems on Ubiquity networks, although not in the last year or so.

I install Ubiquiti UniFi WiFi systems exclusively. If you set up the access points as stand-alone devices, they generally block multicast. If you have the AP's adopted into a controller (like CloudKey), they generally allow multicast. In UniFi, under the Advanced Settings for the WiFi SSID, you can enable Multicast Enhancement aka IGMPv3. This seems to help keep things running smoothly. I've never actually installed stand-alone UniFi APs, so you'll have to consult other parts of the internet to find out how to enable multicast if you don't have the controller.

Hope this helps!

Hi Guys, thanks for answer ! We already tried all settings on Ubiquiti. Also, We isolate automation devices in a TPLINK Router/AP and after 1:30h the Lutron stop to respond and begin to lost packet and the APP won't work anymore. We ask for the Automation Company Provider to replace de Lutron hardware, because there is no more alternatives to solve the problem.I will update this topic when we found the solution. Thanks
