A couple of years ago, I made this DIY add-on to my gate controller to manage it through Home Assistant. It’s Wi-Fi enabled, can warn me if it’s stuck, allows me to check its state, and control it reliably through Home Assistant, and didn’t cost much more than 15€.

Because the gate controller was provided with the house, I didn’t want to replace or damage it in any way, so I needed to make something that works in harmony with what I had.
