Maximum Number of Zones

Thanks for the kind words!

The schematic diagram could indeed be a little confusing seeing this for the first time. Also I made a mistake in a Raspi Pin label (see edit).

Although I don't like Fritzing I did try to make a new drawing like the one in the SIP wiki but with the wiring as shown in the schematic diagram. Hopefully this makes a little more sense to you.

While recovering from surgery I ordered some hc595'. In the coming days/weeks I will try to find the time to make the same circuit and see if I can make it fail too.

Let me know when you have done some testing.
