I got it to change, but I’m not sure how. I keep pressing the pairing button five times in different ways, like quickly, then with long pauses between each press. I saw another posting that said that a blue light would flash between each press, but I did not see that happen. I’m not sure how, but eventually I stumbled across the right set of presses and I could then get the cube to operate as it should via the blueprint. I have no idea if I could repeat this if I had to. This is another example where things are poorly documented, and you have to try over and over to make it right.
For future reference, as this post is often found when this problem happens, refer to this post I made on how to interview this thing and switch modes for ZHA. 🧯 ZHA - Xiaomi Cube Controller.
