One of my Smart Life scenes had some ungainly-long name. Since it was triggered by weather I didn’t think it would be useful in the UI so I went into the UI settings for the scene and “deabled” it by turning of “enable.” It has no disappeared from the interface, and I cannot find anyplace to restore it back as I learned I could rename the scene in the Smart Life app to something very simple. Do I have to delete the scene and recreate it in the Smart Life app? Or is there someplace I can go and re-enable the scene in UI? I use the vanilla interface out-of-the-box on a Raspberry Pi 2.
Go to Settings / Devices & Services / Entities and search for the scene you disabled, you will be able to find it and re-enable it.
