Integrating Fibaro Relay Switch with LiftMaster Gate Controller

Hey everyone, I’m trying to figure out how to integrate my Fibaro Dual Relay Switch with my LiftMaster CB11 gate control board. The goal is to automate my gates using geofencing, so when I’m within a certain distance from my house, the gates open automatically.

From what I understand, the gate control board allows for a switch connection to open and close the gates. The Fibaro relay switch seems like a good solution, but I’m a bit stuck on the wiring details. I’ve read that connecting pins 17 and 20 on the gate board should mimic the functionality of the remote control, but I’m not entirely sure how to wire this up with the relay.

I’ve included some photos of both the gate control board and the relay switch for reference. If anyone has experience with similar setups or can provide some guidance on the wiring configuration, I’d really appreciate it!

Thanks in advance for your help! :pray:
