Hey there,
I'm new to home automation and want to set up a Shelly UNI to make my intercom not dumb. I have done a few searches online but it seems that the intercom in my apartment differs from the 4-wire intercom system which I have found guides for.

Model: HT300

Here is how I think I should wire it, but would really like some confirmation before attempting:
Thank you all
