Connecting eWeLink WiFi Relay to Urmet Intercom for Gate Opening Functionality

Hello
Would you kindly help me to wire my eWeLink wifi relay to my Urmet intercom to open the gates through the wifi







AI: Would you kindly let us know which wiring terminals or connection points are available on both devices, or share photos of the wiring diagrams if possible?

COM under 6
NO under 9

Thank you for your reply.

The guy who installed the intercom told me that 9 is the positive source of electricity (live) for my intercom handset and 6 is negative (neutral).

I know that the relay just closes the circuit just like the silver part (top right) with the 2 edges, when pressed they close the circuit.

So, is it correct to wire COM to 6 and NO to 9? Or, I should connect the COM and NO to the 2 edges of the silver part?

Besides, should I have a separate source of electricity for the relay or get it from the intercom?

Thanks
