Hi everyone, I am attempting to send a string message to a globalcache IP2SL device in which I get the devices attached to the unit. I am using the node-red-contrib-globalcache pallete a  
{"serial":"getdevices,1:1,2"} message payload by using a function which declares the msg.payload as such. unfortunately i am not getting a response back from the GC node out. Anyone have any experience with this device? I am very new at node-red so i apologize in advance. Thank you!
