Hi,

As per attached images I cannot appear to get the CHANGE function to SET the msg.payload even though I have downloaded the demo examples from Meraki. It appears to just output the entire payload rather than just the serial number.

Any help? thank you

you are setting msg.serial - so you need to configure the debug to show the complete message and not just the msg.payload.  
(Unless of course you actually want to set msg.payload.serial instead)
