has 3 colors:
red if the GFCI check fails, or there is an error with the EVSE (you will have to power down the OpenEVSE to clear it)
green when the OpenEVSE is on/ready to charge
blue when actually charging (relay engaged)
just gives you a visual indication of a few states... the LCD display tells you much more, allows you to adjust the current (if for example you use the OpenEVSE on a smaller circuit or travel with it..) the LCD also changes the background color as well as displays messages.
and yes, it just plugs into the I2C port (4 pin connector on the OpenEVSE), even comes with a short cable, and its all assembled, your only job will be to drill the hole (or holes) and mount the PC board., plug in the cable, that's it. The LCD is the same, except more work to cut out the rectangular hole and also mount a momentary switch.
