How to get segment numbers?

[eloo]

Hi,

i have just integrated my S5 Max into HA using this component, or to be more specific the PR from @redphx.

So far so good and its working right now.
But i'm curious how i can get the segments numbers to make room cleaning available in HA.
I've tried the numbers which are shown in the Roborock App (e.g. 1 and 2) but it looks like this is not correct.

So do you how we can find out the correct numbers?
Thanks

Segment numbers greater than or equal to 16 are your custom rooms. I just tried each one to figure out what they correspond to.
