OK... what's really strange is that a couple of my 2-Wire SwitchLinc devices somehow managed to get into this mode all by themselves, after just turning on the switch manually. So really I just wanted to be able to turn this mode *off*, because like you said, it's really visible. I'm also somewhat curious what would cause this to happen in the first place... besides the simple fact that 2-Wire switches are by nature less reliable than switches that have a neutral connection.
Anyway, I was hoping there would be an easy way to do this without a factory reset. But unless someone else has any ideas, sounds like that's my only option...
