It appears that they have used the normal Button status packet to show the state of the Relay channels (1 to 5) and channel 6 is used for the external input, including Long Press.
(See Page 3 of the PDF)
For now, if anyone does ask for the status of the external input, I'll just advise them to manually add a VMB8PBU or VMB6PBN with the same base address as the VMB1RYS. and watch Channel 6
Thanks for adding the VMB1RYS as a new relay type (into the pull request)
Just one minor detail, that can wait until you next have enough free time to think about it...
The VMB1RYS has an "External Input" which appears on the bus as a button event.
