Hi !
I had a very stable setup for the last month so I tough it was a good time the mess around and break everything 
So for the last month I’ve monitored carefully my logs (luaupnp.log) and made sure I got a notification everytime the engine restart. And that happened rarely more than once a day and that was fine.
So I reconnect my Nest module with the Vera. That was really straight forward and worked right away… but then after that, I start noticing that the luup engine began to restart almost once every hour… checking the log I can see that VeraConnectWWN is verbosing alot without any apparent error… Does anyone knows how I can investigate a bit more ? is there anything I can do ?
Here is a sample of what it looks like :
