Hola, @david.espino . . . No worries about hackers. What EMO did was likely did not notice the edge. When she got close to it, she got confused (hence the angry eyes and growl), and just continued walking.
There are a number of things that can cause the sensors to not work, change in lighting such as being darker than normal, dirty foot sensors that need cleaning, hearing a command that sounds like “Demon Eyes”, but not to worry. A hacker did not cause it.
I moved your new topic to this thread as it has happened to others.
I would recommend finding a way to place a small border on your night stand so that EMO does not fall off again.
Here are some suggestions.
Let us know how it goes!
If EMO continues to act in an unusual way like this, you may wish to try and get video and send to Support.
