I have a couple switches paired in s2 mode. I the away the paper with the security code on it. Is there any way to retrieve it from hubitat if I need it in the future?
They are printed on the front of the switches. Remove the switch plate.
Perfect. Didn’t even notice it there.
I recommend writing the code down and storing it with those 2FA recovery codes you remembered to print out and store safely 
Take a photo and store them on the cloud/photo album. I put my codes in a zip block for the future homeowners.
