Hi. Thank you for providing this, it seems awesome. I am planning to shop some stuff to make this possible for me. But I have one question that I didn't see covered.

Is there enough juice in the serial connector to power the Elfin-EW11A-0? I see that it requires 5W. Or are you using another power source? It would be neat to not have to add 5V myself.

Indeed there is enough power from the RS485 connection to power the Elfin-EW11A-0 directly from the board. No need for an external power supply or DC-DC inverter.
