I don’t know if others have this problem, but sometimes my vera will lose connection for no obvious reason. Luup restarts as well for unclear reasons. Most often things will come back to working. However, twice when I was traveling, the system would not come up and my house was not controlled nor could I access it remotely.
So a simple solution:
I bought a cheap battery back up timer from Amazon

and restart the Vera at 4 AM every day. This has improved reliability greatly, and if I am away, I can still get to the system.
In order to debug further, I’ve set up notification from System Monitor app to notify when LUUP has restarted or the system reboots.
Lastly, since it came with two timers, I use one to reboot my cable modem every day, which has had a significant effect on keeping my download speed at maximum (Comcast advised me to manually reboot my modem every week…this is easier)
So simple solutions to my problems…sharing in case you have a similar problem.
