I dont understand how Zipabox works with x10 devices. AFAIK I have to buy the additional 433Mhz module, which is not working with x10, because x10 TM13 and similar modules are not supported. (they dont have the required pairing mode) What does the 433Mhz module do for x10? I read it was necessary to buy at least the serial module too, to connect CM15 via USB. Still no support for 433Mhz RF X10 devices, but 2 (!) PLC devices connected to the CM15 will power on/off and dim (?). No "switch all" command, no extended commands (blinds, percentage dimming)? If this is what Zipabox understands as compatibility, then it is not the right product for me.
