There are two "all off" commands. All lights off and all units off. Some modules won't respond to all lights off, many scene-capable receivers have this as a programmable option.

The all lights/units off commands are house-code specific. If they are sent on the module's primary address house code then the module should respond. I'm not sure if the behavior of an all ___ off command on a scene address housecode is standardized between different brands/models. It doesn't sound like it reponds on the receivers that you are using.
