For those having issues with lightify devices.
I had the garden spots either need to be power cycled or resynced every few days to a week, constantly.
Also the tuneable white lights need to be resynced periodically especially after power outages…
I finally bought a lightly hub from amazon and updated the firmware on all the devices and have not had a problem since.
The reset for all lightify devices is on, off, on off etc 5 seconds each and then on the 5th time for 10 seconds to reset.
hope this helps others.
