(*

    NBIRTH message. Any time an input changes on the EoN node, a NDATA message should be generated and published
    The following is a representation of a simple NDATA message on the topic:
        spBv1.0/Sparkplug
 B Devices/NDATA/Raspberry Pi
    
   The 
Group ID
 of this EoN node is: Sparkplug
