It's a clock, why does it need config? If you need to adjust the time and light, give it a poti or button for manual adjustment. Might even give it a radio to grab time of the air. Even a sim card to get NTP of the WAN would be simpler than having to connect to it.
I know, I know, you wanna configure the light to flicker as signal for ... failed log in attempts. :)
PS: at least something was realized. I never finished my alarm clock design because LEDs do draw energy, more than would be feasible for battery operation, I thought. Quick check: 2000mAh at 1.5V in an AA cell, 20mA at 1.4V per LED. So, with 100 LEDs like here, I would be swapping Batteries by the hour; And a single LED pulsed at 1/100 s might run for (barely) a year.
