I have seen many garage door opener solutions. However, many of them are far more complicated than I wanted. So, I simply soldered some wires to the buttons on my GDO and I cut the wires to the "memo1" and "memo2" buttons on the left panel. I soldered the GDO wires to the panel buttons. The "memo1" and "memo2" buttons are by far the least used buttons on my wing (I've never used them once), so this will make them buttons I'll actually use.
