Which units are 2way units

[MindBender]

Who can tell me which micro modules are 2way modules, and wich ones are not? Are there 2way wall plug modules, both dimming and switching, available too?

Technically, if a module can't be triggered externally, a 2way interface wouldn't be required: Simply watching the bus for events and setting flags accordingly should suffice. Am I the only one paranoid enough to want 2way modules only?

2 way would always be required, so it could acknowledge it receive the right command.

So, I too would prefer to have all my modules with 2way communication instead of "believing" that it received the command without ack.
