    Hi, yeah. You can use each of the two outputs for that; in the Shelly Uni the ESP8266 Wi-Fi chip controls two TLP172GM photorelays that can be open and closed, "shorting" both leads and closing any circuit you attach it to.

    Thanks so much. I checked and the current required is 14mv. I connected it up as you said and it works perfectly.

    One question though. When I press the door open button (on the intercom itself) just for a second the door unlocks a stays open for 20 seconds. The button is spring loaded so turns off immediately as you lift your finger.

    When I tap the button on the Shelly app it stays on (the circuit is switched on) until I turn it off. Is there a way for it to turn off automatically after say 1-2 seconds? Or only staying active while being pressed?

    I tried setting the button to “momentary” but the button still stays on after taking your finger off it.

    I want to use a shelly uni to do two things :

    1) Sense the buzzer has been pressed on my intercom.

    2) Act as a switch to connect two 9v dc wires to open the door

    It seems the sensing function can be achieved by connecting the two wires to Shelly uni pins 3 and 6.

    However I am not sure if the Uni can act as a switch to close a contact between two wires.

    Could anyone enlighten me if this is possible and if so what would the wiring be for the two wires to be connected?

    Many thanks
