There's an Association tool created by @ericm for Inovelli devices.
Lifeline association means something different to me than "Association" I read in forum messages. Lifeline association is more of a route function, in the sense that it's necessary for the device to get status info back to the Hub. Device manufacturers create Lifeline association occasionally limited to one, but sometimes more. Group 2 Association is what I normally think of when I see a standalone association reference 
But give the tool a try, it might do what is needed in this case.
