I have an ELK-M1G with all hardwired security inputs. There is also an Ethernet interface, a Two-Way Interface and Relay Output boards. For my home theater system I am thinking of getting the Logitech Harmony 890 remote with Z-Wave capability. I know I would have to get the ELK-M1XZW in order to enable the Elk on Z-Wave. I understand that the Elk would not send zone status updates to the remote. I want to use the Logitech to send commands to the Elk. Such as, Whenever 1111 is received from Z-Wave, Then activate Output #17 for 1 second. My question is this....Will I need an additional "master" Z-Wave controller? I have searched forums and websites and Elk states a requirement for a seperate master Z-Wave controller. Will I need something else or will the Logitech send commands directly to the Elk-M1G?
