Shade comm problems

I am on site at a job with 30+ shades that has been working fine for 2+ years. Client called a few weeks ago to report trouble with (2) shades not working.

When I got here today I opened the QS software and tried to wiggle both problem shades. Both reported as "off line" so I went into diagnostics and both shades reported communication issues.

I removed and restored power to each shade, LED's cycled on the motors, shades report as OK in the diagnostic "verify devices" screen, but they still do not work.

Ideas?

Hello tkucsan,
Thank you for your post.
I would recommend factory resetting these shades, reactive and transfer. If the issue remains give us a call at 1 888 LUTRON1 and we can do some live troubleshooting.
