What does this light indicate? I had troubles for hours on this new installation.  
For the first hour everything was fine, then I saw it was offline. I noticed it was trying to reset unsuccessful, and wouldn’t respond to trying to add a new door. This might have happened because I included an underscore in the device name. I walked away from it for 14 hours.  
It was showing a steady cyan, when I tried again, and it reset with a new name like a champ. It has been online for 2 hours.  
So my curiosity causes me to ask what the cyan LED indicated.
