Shouldn’t be too hard for them to do, +1 from me.
In the meantime if you want it now you can send anything back to the dashboard. See my post here: Dashboard values don't update Obviously modify the code to send back the IP address instead of the values of the DHT11 sensor. A tip for you: the IP address is in an array so use something similar to the function below.
void printIPAddress()
{
Serial.print("My IP address: ");
for (byte thisByte = 0; thisByte < 4; thisByte++) {
// print the value of each byte of the IP address:
Serial.print(Ethernet.localIP()[thisByte], DEC);
Serial.print(".");
}
Serial.println();
}
