@bravenel I tried to set up a simple condition with a wait for expression and found an issue that I can recreate.
For this example I set up the simple condition for a motion sensor. When I try to add the Wait for Expression action it starts out ok.
But when I try to Define Expression --> New Condition I get nothing.
I can select Timeout/Duration or Cancel this action.
If I do the same thing but use a defined condition, the resuting action is the Wait for Expression only. The Simple Condition is completely missing.
