Just getting into some home automation and am thinking of using C-Bus for the lighting as the HA controller supports C-Bus. Doing some research it appears that it is mandatory to have a 5500PC to set the unit address for each unit on the C-Bus. It appears seems an expensive option just to be able to set addresses. Been quoted 2 for the 5500PC and 5 for the 5500PS is there any other alternatives? I require the address to be set on a test set up I am putting to gether to verify the HA controller and Cbus bit all communicate together before they are integrated into the HA system. Just seems a price level of entry just to be able to integrate their system. Are there any other mandatory tools that are required before you can start using C-Bus on a system? Appreciate any suggestions and dcomments. Thanks, Fleetz
