Hello, I have a problem with connecting a smart device and a bell button. I have a supla sonoff automat sonoff input 230 potential-free output connected to the control unit and to this I wanted to connect a bell button (pins +;- ; gnd; nc; no). Separately, the devices work, but when I connect and bridge the pushbutton together with the control unit, the pushbutton works and the control unit does not switch on the gate. Does anyone have an idea why?
