I have 12 large serena shades that are hard wired in my vaulted living room, so 6 upper and 6 lower. My schedule (using the Lutron App) sets them to open, say, at sunrise. However, what happens usually is that at least one of the shades won't open, even the Lutron App indicates they are all open as per schedule. Then I will have to use the app to open it manually. Such issue doesn't happen every day but is very frequent, and any number of those shades could be problematic on a given day. My initial guess was that opening all shades at once may draw too much power for the wires to be able to handle, so I created two schedules, one for the lower shades and one for the upper with a few minutes gap, but the issue persists. What could be wrong and how can I get it fixed? Thanks
