After a while you forget. I should remember my old Fortran-77 procedural programing days reflexes.
I was a bit lazy and I blindly reproduce the rules from this youtube video : Color-changing LIFX bulb automation with Hubitat Elevation,… just to remember after a few days that this is the 101 newbie programming error that I was doing at the University ( I rather used While loop than Repeat loop myself 
)
Enough complaining.
Consider that rule :
What is the error?…. Until Time=22:15 in the UNTIL condition. What if at the time of the evaluation it is not 22:15 exactly but 22:15:01….. The condition will be false and the Until condition will never be true. (in my case there is a wait in the Repeat/Until (not a good idea, but I was lazy copying the rule as I previously said)
See my log below...
Solution – I set a variable to True with another rule that will stop the Repeat/Until.
Maybe there is something more elegant. I was looking for Repeat Until time <= 22:15 but it does not look that there is that possibility.
Although using Between two times, setting 22:15 and 22:20 would probably be ok. Just that I have another rule available to set that variable.
