The function contains something very similar to:

msg.payload            = {
    "method" :  "PUT",
    "url" :     "/digital_out/INDICATOR_0",
    "body":     {
        'value': msg.payload,
    },
    "token":    "myToken",
}
return msg;

Add a dashboard "switch" node:
Make sure you can actuate your mote's LED from your phone

configure the switch so it shows a lightbulb which is "on" or "off".
