Thanks. My only hassle against using a SV is that I would need to install a outdoor access point for the WiFi signal reach the gate where I would install the SV.I used a Sonoff SV and had to pop off the resistors to make it dry contact. I know almost nothing about electrical engineering but I wouldn't put any voltage through it, it's supposed to just bridge COM and Trig to open the gate.
For the Sonoff basic route I would install it next to the gate monitor/intercom inside the house (with great WiFi coverage) which only has 220v terminal block (that the intercom is connected to) and the trigger wire & old video/audio wires for the gate hidden behind the intercom, I did find this video to mod the basic for dry contact:
