saw a Madalay(half-sister to the Tuscany and Palazzo) that solved this problem
attaching the 'sunguard' or privacy screen directly to the awning
they used three 6'-7' poles, driven into the ground directly under the edge of the awning, and mounted their screen to this. This way the auto retract can still function properly in high-wind, but not effect the sunscreen.
while this might not seem the easiest option for short stays, it's certainly a quality idea for long terms. This might work for you and you won't have to worry about messing with the wind sensor.
On our 2014 Palazzo 33.3, we purchased the carefree sun/privacy screen that just slides into the awnings 'accessory' slot, and it rolls up right with the awning when I leave. I usually use tie downs during the stay to keep it from blowing in the wind too much, and those tiedowns also help keep the main awning from moving as much as well.
