Connect [Shelly Plus 1] to Garage Gate Opener [Marantec CS 320]

[Christof S]

Hi Shelly folks,

I am trying to connect a Shelly Plus 1 to my garage gate opener Marantec CS 320.

I thought I use the exisiting interface for the wireless remote according to this pic from the handbook [below].

What do you think - would that work?

How would I wire this to the Shelly?

The description here is not helpful for me noob.

 

Thanks for any help!

It would be brilliant to get a link to the manual of the gate opener!

Here you go: https://login.marantec.com/einbauanleitungen/montage-anleitungen-ersatzteil-platinen-cs-320-und-cs-320-fu

English - from page 64 onwards you can find the overview of the internal connections

for a similar opener (Marantec CS 300 - has the same connections) I found a wiring diagram - tried it and it does not work (the Shelly does not power on) 🫤

Unfortunately, plus and minus in the above sketch are interchanged. Please use this diagram:
