Up for sale is a wifi gate controller by nexx, it was specifically for u.s. automatic but could be wired to any gate really. End was cut off per instructions for install to older gate board. I had constant connection issues where 50% of the time it would need rest to reconnect to the wifi but I had it in a remote location with a point to point wireless connection, maybe you will have better luck I just replaced it with a unifi door hub. Asking 50$ was over a 100$ new
