I have my Texecom alarm panel connected to Vera Lite via IP and occasionally the panel gives comms alarms which clear almost immediately. Today I managed to catch one as soon as it occurred, and when I looked at Vera’s LuaUPnP log there’s a gap of 21 seconds where nothing is logged. Obviously this is odd, since there are normally dozens of log entries every second.
I can see nothing unusual in the log entries immediately preceeding or following the gap, but would be happy to post the log if anyone could throw any light on the cause.
