Hey Everyone - thanks so much for all of your help with this - here's what I wound up doing (a little pricey but I think it's going to look nice and be very portable):
2 x 2486DWH8 KeypadLinc Dimmer - INSTEON 8-Button Scene Control Keypad with Dimmer, White $69.99 $139.98
2 x 2402WH Tabletop Enclosure for KeypadLinc, White $17.99 $35.98
2 x 2401CLB 6 or 8-Button Change Kit for KeypadLinc, Clear $5.49 $10.98
S&H $11.11
Sales Tax $15.42
TOTAL $213.47
from
www.smarthome.comThis will provide monitoring LEDs to 16 house letter/unit number pairs that don't have to be consecutive (or even the same house letter for that matter).
I'm contemplating placing a thin clear plastic sheet on top of the buttons inside the enclosure so they can't be pressed (I STRICTLY want this to be for monitoring with the AHP/CM15a doing all the work).
I'm going to be assembling all of this stuff when it arrives this weekend and I'll let you know if it didn't turn out as I had hoped.
Again, thanks for all the guidance/direction!
Take Care... Mike.
