Hi,

I have a few Smart Home one time events using NodeRed, f.e. a sleep timer, light toggle and so on.  
Problem is, as soon as I re-deploy after changing some stuff, all messages which have been incoming are re-processed, and all outgoing are re-sended: light toggles, sleep and wake up timer start and so on.  
I always thought, a QoS 2 message for example, is meant to only ONCE being processed?

Is there any way to change this behaviour, i.e. just save new notes without re-processing and re-sending?

Is the `retain flag` on for those devices ?  
Note that you can change the deploy setting to `modified nodes/flows` only.
