Non-trivial.
CBus components are connected together using a two wire bus, which
distributes power and carries data.
Clipsal provide the mechanisms to interface to their bus system at a
RS232 level by using their interface adapter, some details of the
protocol of which you can get from their website by an online
signup, deeper details require that you sign up to the Clipsal NDA.
The wire level protocols are not published, not even under NDA.
The cost of the RS232 adapter is more than a neo.
