Spent two days trying to discover why two of our Pico remotes quit working. Replaced batteries, moved them to different locations. Finally, tried one of the other Picos in the house, and it didn't work, either. Then I remembered I had ben in the "rack room" closet. Moved the Lutron hub back where it was before I moved it, and a miracle happened. I guess I now realize how little we actually the dozen we have around the house, relying on movement and time. These two are just for Night Mode vs. Day mode in main bedroom. We both hate talking to a machine, especially first thin in the morning.
By the way, no real lesson learned, except quit messing around in the rack room.
EDIT: I did not spend the entire two days on this! I also drank alot.
