Wiring Avanti MPS 12

I now seem to be getting very low reflective states from door closed, during the day. Night seems quite reasonable and high
Currently at so will have to check laser alignment when I get home
Reflection is at about 6. Door open goes to the neighbors wall… gives 0 reflection
(oops might have to look into that … )

My garage has no windows, only light would be from the top of garage etc.
No where near as much as.

Is this perhaps a scenario where my garadget unit could do with a light protective shroud?
(given reflective sticker is still correctly in place etc)
