The LiftMaster 8550W uses Security+ 2.0. How to connect the ismartgate door opener?

All garage doors that use Security+ 2.0 cannot receive external open or close commands through a contact switch, which is why most smart openers are incompatible with these models.

Fortunately, ismartgate offers the Switch Adaptor as the sole solution where you can add the Switch Adapter to your wall push button and connect it to the ismartgate device to enable its use.
