I have the same manual sensor. If the wind picks up and the awning flaps it is time to bring it in. This is called common sense and works both day and night.
If we are gone for the day and we expect wind, we pull it in. At night if it is raining and we want to keep things dry we leave it out. If it is the dog days of summer and we are begging for any type of breeze we leave it out. If we are unsure we pull it in.
At times when we are around but not at the campsite we will run tie downs, as needed.
If you are unsure, just push the button, it takes maybe half a minute.
Good luck
