Hmm, it's quite possible that I mixed up the SCL and SDA of the I2C breakout board I was using for the relay module.. I got confused looking at the pinout picture in the Connection instruction because the picture seems (to me) upside down compared to the orientation on the board, and the ground is red and the Vcc is black.. I even went so far as to measure the Vcc to ground to make sure I had the right pin! I'll double check it all again before I hook everything back up though if you think that had something to do with it?
I had the same struggle with the relay board not working; come to find out that the Common/NC/NO diagram they use looked odd to me and I wired it up wrong. I guess nobody uses ladder-logic much anymore, or at least they don't just assume everything like I do!
Thanks so much for all your help so far, your customer service is beyond amazing. I will remove the chip here in a few minutes. Do I need to short anything out in it's place?
