You’re sort of on the right track @kreene1987 . The custom capabilities per device between the new and old app on some devices are not directly compatible. It has to do with the way the code is written for presentation, custom capabilities and execution. My Inovelli 4in1 show temp on home screen Classic App and displays motion on the new.
To add insult to injury the latest plans to drop groovy is not going well with community developers to get everything to cooperate and function as desired. There are alot of changes in the works for ST, maybe good or bad depending on what the end user requirements are from what I have heard. I have devices that still don’t show all functions in the new app even though ST has sent me migration notices claiming my devices are operational in the new app. Functional to a degree, but not all capabilities show up. In addition to trying to get my own smart apps and dth working 100%.
