Hi @scott_Sedman,
Unfortunately it’s the 398LMC that’s the problem. Unfortunately, this is the one (very old) wall button that just doesn’t work reliably with the GDO blaQ. There’s a post about it here and I’m working on re-organizing our knowledge base so this is easier to find.
I recommend replacing the wall button with the 889LM wall panel and then set the protocol setting on the GDO blaQ to Security+1.0 with smart panel
