Here is another version that is a buck and a half cheaper with a much simpler looking board.

Actually thinking about trying one on my gate. I also want to rig up a camera on the gate. An intercom feature would be nice too but I can use cell for talking.
The relay gives you momentary contact, I think you have that figured out. There is other styles that use the same app, haven't played with those.
For your gate I think, you would not even need internet to the gate. The relay and a wireless router at the gate. Then for those that need access share the connection which is password protected. Of course if you want to open it for say a plumber, to get in, from work then you would need internet access. Then feed back for when the gate is actually closed and the plumber is not walking off with half your house would be nice. That would be the camera. Which I too would like to rip up. The system I bought was wireless and the wireless signal from the camera interferes with the wifi signal hug:mur:
For me it is simple it is about the ice. Getting out of the car, the loader or the 4 wheeler to open the door and slipping on the ice in the winter is the issue. Open the door get out on the level safe ground. So, i need to have the opener with me and working.
Slipping and falling on the ice is bad! I have had my hip replaced, knee and shoulder surgery. I want to be able to get out in the winter. When I had my hip replaced I had to take the 4 wheeler from the house to the shop, getting off to open the door was not an option.
So, for me for three doors, for a system that is reliable and I will always have with me was $80.
Now I have spent money on technology that has not been worth it or more trouble than it is worth. That would be the video camera system. I am generally pretty careful.
Technology has its place. if it was not for technology there is a lot of things we would not have today. It is thinking about it and using it and spending your hard earned money on it wisely that is key. In my case this technology has enhanced my life, it was cheap and easy to do and it should be shared.
It is change for the sake of change that I have issue with and if it ain't broke don't fix it.
