I have this idea of writing an app/something to make the gate, that we have in front of our house, smart. But I just don't know where to start. I assume that the gate uses IR because we have remotes for it, but I'm not sure. The gate also has a codepad and I want everything to work simultaneously. Meaning that when I'm done with my project the remotes and code still work.

So, can anyone help me to get started with this project?

  • Would it be logical for the gate to use IR? What would it use otherwise?
  • Should I try to read and emit the same signal using a Pi/Arduino?

As mentioned in the comments...

Assuming the controller has a button that will trigger the gate to open then you just need to find a way to "press" that button.

The simplest way is probably to attach a relay across the 2 wires to the button. The relay can be triggered by something like a esp8266 or the GPIO pins on a raspberry pi.

The question is then if it's a momentary press or if it needs to be held while the gate opens.

If it's momentary then the relay just needs activating for a second, if it's press and hold then you will need to activate the relay for the length of time it takes for the gate to open.

That is a very simple approach and doesn't cover things like feedback on if the gate is open/closed.
