+## LED Status
+
+Some ESP boards have a built-in LED, on pin #2.  This LED will flash to indicate the current status of the hub:
+
+* Fast flash (on/off once per second) means the Wifi is not configured.  See [Configure Wifi](#configure-wifi) to configure the hub.
+* Occasional blips of light (a flicker of light every 1.5 seconds) means the hub is on wifi and ready to operate.
+* Rapid blips of light for brief periods (three rapid flashes) means packets are either detected from a device or are being sent to a device.
+* Solid light means the Wifi waited to be configured and gave up, or something went wrong with wifi configuration.
+
+You can configure the LED pin from the web console.  Note that pin means the GPIO number, not the D number ... for example, D2 is actually GPIO4 and therefore its pin 4.  If you specify the pin as a negative number, it will reverse the LED (the built-in LED on pin 2 is reversed, so the default is -2).
+
+If you want to wire up your own LED on a pin, such as on D2/GPIO4, put a wire from D2 to one side of a 220 ohm resister.  On the other side, connect it to the positive side (the longer wire) of a 3.3V LED.  Then connect the negative side of the LED (the shorter wire) to ground.  If you use a different voltage LED, or a high current LED, you will need to add a driver circuit.
