Hello,  
I have implemented a mapping from MQTT to OPC UA (OPC compact server) in Node-Red.  
After restarting the host, it happens again and again that the OPC Compact Server is not accessible.  
After a deploy, everything is OK again.  
Is there a function in Node-Red to trigger an event-driven deploy?

I would be grateful for any help
