I have one Pi3 with Alexa and MagicMirror, and a second Pi2 with just Alexa, I created two devices in Amazon Dev, with two different product IDs, but it assigned the same secret codes to both. Now when I ask either one of them something they both activate and answer. Is there a way to get it to assign different codes and still have them talk to each other. As in, put something on a list from either Pi. And the other wont answer? But the same list is used.
