Just tried to add it and it did not add. I specified the address that I did find in the battery compartment but it made no difference.
I also see that the keypaddimmerlinc device still shows OTHER as the device type. I added that by using the button press technique from the keypad. I had specified the type but the software must have rejected. that.
When I try to change type, it says that I cannot change the “category” of a device.
