Until a couple of weeks ago I had rock solid reliability. Now, sometimes things will obey programming, other times not.
My programming is quite simple. I am turning things on and off at a set times. My most recent failure is I have two Z-WAVE switches that I want to turn off. One turns off at 8:00 PM, the other at 8:01 PM.
The programming to do this is quite simple . The switch for the 8:00 PM time turned off successfully, the 8:01 PM switch did nothing at the appointed time.
When I control the switch “manually” using the iPhone app it always works.
Both SmartThings technical support as well as myself, has used their website in order to get routines un-stuck. But they appeared to just get stuck again later.
