I’ve been in contact with Jason from support and it was determined that the GE 12727 (non-dimmer) and 12729 (dimmer) have different methods of reporting digital vs physical interaction with a switch. Currently the DTH source as reported in the IDE is as follows:
12727
Digital - DEVICE /digital
Physical - DEVICE /physical
12729
Digital - DEVICE
Physical - APP_Command, DEVICE
A feature request has been put in to see if it is possible to change the GE 12729 to report similar to the GE 12727. Below is my example in which Jason was able to replicate.

12729 (dimmer)
