@dylan.balloo You just need a USB to SERIAL cable/breakout board/adapter that has an FTDI chip on it. You then connect the FTDI based usb to serial device to the arduino serial pins and plug the USB into the Vera. Vera will only communicate via Serial if the chip it is speaking to is a FTDI chip. No atmega, no cp2012, no CH340, etc... Only FTDI
