I have a Liftmaster MyQ garage and Liftmaster LA400U gate operator, both using Security 2.0+ technology. I used to have a Liftmaster 828LM MyQ Wired Gateway and had no problems connecting both the door and the gate. Since I've upgraded to a Chamberlain MyQ-G0303-SP, I can connect only to my garage door and no longer to the gate. Is there an explanation for this? Is the Chamberlain MyQ-G0303-SP somehow different from the Liftmaster brand G819LMB? If it is, can Liftmaster/Chamberlain replace it or somehow update the firmware instead? Thanks, pretty darn frustrated here.
