I apologize for my ignorance regarding the absolutely stupid lack of an Entry Delay in STHM. I thought they would have learned after the SHM debacle.
I moved 100% to Hubitat a bit after I modified and tested SHM Delay with STHM and the new app sometime around early December. From my experience with helping users get SHM Delay working, I find most problems are the user deciding to avoid reading and following the detailed directions, although with the new ST app it may be something else. SHM Delay is a giant hack to SHM, nothing much changed using STHM.
While testing the app with STHM I found many of the child app (profiles) created with the new app have the INCOMPLETE status, making them unusable with SHM Delay. The solution is to create the profiles with the Classic app. My suggestion was to stick with the Classic app.
However, without warning, ST silently removed Routines and SHM from new installations of the Classic app. So at this moment it appears things are a mess and as @oldcomputerwiz says “something is wrong with new SHM Installs in the new app”. As far as I know he may be the only current install of SHM Delay working with STHM.
