I am getting this error occasionally: “An error occurred while executing the event: java.lang.reflect.UndeclaredThrowableException”. I have 4 Ceiling Fans and I am starting them based on my Furnace Fan/Blower starting. Sometimes, all 4 start with no issues, but occasionally 1 does not start and looking at the logs, I see what I have pasted above. This also occurs on occasion when I use the same piston to stop the ceiling fan. Each fan has a separate Piston to start or stop it.
Any thoughts and help would be greatly appreciated.
