Identifying Conduit MAC for ID in NodeRed

[Campbell Elder]

Would like to append LoRa data in the nodered flow with the Conduit MAC address so can identify which gateway data has been received though.
Is this possible, and can any one show how it’s done?

The LoRa starter kit bluemix flow does this, you can download it from the device hq app store.

In short, use an http request node to send a GET request to http://localhost/api/system/macAddress. You can then use a function node to store that in a global variable (context.global) so other function nodes can use that variable in the future without performing another API request.
