If you have stumbled on to this thread then you may be looking for a solution to the Logitech Harmony Hubs losing local access on your Unifi network. When this happens the MeiHarmony plugin can't connect to the hub and the plugin throws connection errors. You will know you are having this specific issue if the Android app or iOS app thinks the hub is in AWAY mode even though you are at home on the same network as the hub. There have been discussions about long power cycles but this did not fix the problem for me. And there are similar issues with iRobot Roombas.
This is a known problem and has to do with broadcast messages being blocked by the Unifi controller. There are several posts on the Ubiquiti forums on this problem:

Turns out that the Harmony Hubs needs to be able to broadcast and by default Unifi APs block broadcast messages. The simple solution is to turn broadcast blocking off. In the Unifi control set up, in the Site settings, there is an option called Auto-optimize Network. Make sure this is turned off. (see attachment).
Another HomeSeer user MNB (Mike) was having the same issues. This is what he did and it fixed a couple of his problems:

Make sure you hub firmware is up to date (4.1.5.250 as of this date), and that you have enabled XMPP (in the Harmony app: Harmony Setup -> Add/Edit Devices & Activities -> Remote / Keyboard & Hub -> Enable XMPP. Prior to 4.15.250 you needed to load up special firmware, but as of 250 this is now an option that can be enabled/disabled.
Also, if you are using the Harmony desktop software check that you have the latest version. I don't think it updates automatically, so you may need to download and re-install it. This will allow you to update the firmware to 250 if it has not happened automatically.
Hope this saves you some time. I spent several days trying to fix this and even rebuilt the Hub from a factory reset to no avail. Should have done some more searching before spending so much time on it.

Another HomeSeer user MNB (Mike) was having the same issues. This is what he did and it fixed a couple of his problems:
1) Turned off "Auto-Optimize Network" within the site settings,
2) Within the affected Wireless Network(s) turned off "Block LAN to WLAN Multicast and Broadcast Data",
3) Went to the Client list and performed a "Reconnect" on all of my affected devices, in my case it was both Harmony Hubs and Roomba's,
4) Went to the HomeSeer PC and performed ping -t 192.168.1.X (Harmony hub) and eureka! I now have ping-able WiFi devices!
