I found in my logs that my bridge (v1) thing is going OFFLINE frequently, the reason is apparently a lost connection. When it happens, the bridge is going ONLINE 10s later. It happens even during the night when there is no activity in the house. The frequency is not regular.

Here is the line triggering the update of thing to OFFLINE:

openhab-addons/bundles/org.openhab.binding.hue/src/main/java/org/openhab/binding/hue/internal/handler/HueBridgeHandler.java

Line 738 in 283ae59

    
           updateStatus(ThingStatus.OFFLINE, ThingStatusDetail.NONE, "@text/offline.bridge-connection-lost");

I guess it is normal for the bridge to indicate offline if the connection is lost.

The real question is what is causing the connection to be lost?

The real question is what is causing the connection to be lost?

Yes, that is the question,. I will add logs to the binding to understand in which case it happens.
Maybe due to authentication....

There was a fairly major firmware update for v2 bridges on Aptil 25th, so maybe they pushed something for v1 at the same time..
