Update. Seems to be working now.
I had set up a simple routine to turn on a smarththings lamp when a ring motion sensor triggered. Suddenly, about 4-6 hours after creating the routine, the light went on when I entered the room.
So today I turned off PM again and tested my Ring alarm routine. Worked like a charm, turning on two lights and setting off a Utilitech siren.
Will continue to test periodically, but Simple Commands seems to be the simplest solution!
