Local IoT device's unique value

Not sure about JS, but in Python you can do this:

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(('10.255.255.255', 1))  # any address works
ip_addr = s.getsockname()[0]

import uuid
hex_val = '{:012x}'.format(uuid.getnode())
mac_addr = ':'.join(hex_val[i: i + 2] for i in range(0, 11, 2))

You can also get the CPU serial number from:

cat //proc/cpuinfo | grep Serial

You can use process mode to get those information

Thank you!!!

I got it.

const serial = require('proc-cpuinfo')()["Serial"][0];
