One issue that is plaguing me is current requirement. The garage needs at least 16 zones (2 stories); that quickly adds up using average 20mA LEDs to show status. I also want to have visibility of the other buildings from any keyboard, even more current required.

I have several older units of this graphic LCD, mine are 90-100mA:

Much lower current required than LEDs and much more flexible.
