Hi All, Newman posted this comment in a previous thread. >>Trigger Groups and Action Selectors are analogous to a C-Bus Group Address >>and Level. So, an Action selector of 2 corresponds to a Level of 1% (there >>are 255 action selectors but only 100 whole percentages). >>To make the Multisensor set the Trigger Group to 1% (Action Selector 2) is >>change the key functions in the Multisensor from OnKey to Recall 1. Then set >>the Recall 1 level to 1% Can this really be correct ? Setting the recal level to 1% would actually trigger action selectors 1,2 or 3,4,5 depending on how you translate. The mapping from % to x/255 is not unique. If this is true, then you could only use action selectors 1,3,6,8,11,13,16,18 and so on to guarentee uniqueness. Or am I way off the mark ? What would make sense is only allowing a pir to trigger action selectors 0-100 or something like that but in that case pir 1% should map to action selector 1 ????? Thanks Chris
