exactly. I think wherever you program it, it gives some kind of buffer around the location and then triggers it on the edge of that buffer.
Exactly. I have multiple garage doors, so I reprogrammed one of the 3 from a location up the street. The menu drops down when I am further from my house, and only one button is shown Green (the other 2 are gray). All 3 function, however, and my garage approach is such that my openers can hear the signal just fine from further away. (My garage is a side-load, and I approach the house from the left, but pull into the garage from the right).
A benefit to only reprogramming one button is that the other 2 buttons' buffers include the garage itself, so the menu opens at the garage door (for 2 buttons), and also up the street (for 1 button).
I'd like to be able to set the buffer radius size, as suggested previously. However, reprogramming one button from further away is a reasonable workaround.
