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.
