This one works? I thought this is merely a switch. It should be the other type which has separate power for control and switch itself.

Yes but I think the MINIR4M is the wrong one to use. My understanding of wifi switches is that there is two types. One that power itself like the one you mention MINIR4M. If you connect the L and N from the power, once you turned on the switch, the L will be channel to L out. You would not want to feed 230v to your DC autogate board.

Instead you should be using dry contact which feature an external power source which is separate from the circuit itself.

I myself also using something similar to what you mention. I had mine connected at my autogate wall switch instead in the autogate box because I fear of my wifi coverage not being good enough. Power using USB 5V (just use any regular phone charger).

Look for the transformer. There will be a couple of wires out of them. Then look at the board inlet power.

Why not take a picture and ask the installer to show you where the 12v are. Just hope it was not soldered dead like some of the board out there. Normal cheapo auto gate board all have screw in type which allow easy way to add extra wires.
