// device, below we implement a very generic routine that simply blinks the internal LED of the ESP32 the

// for each physcially-attached device (light, shade, fan, etc), but in practice this is overkill.
|

|

// Note that the blink routine below starts by turning off the built-in LED and then leaves it on once it has blinked
|

// the specified number of times. This is because when HomeSpan starts up if confirms to user that it has connected

// to the WiFi network by turning on the built-in LED. Thus we want to leave it on when blinking is completed.
