I got my system set up with a ratgdo 2.53i and an expansion board following the instructions provided by @hambandit. I’m using the ESPHome implementation. I initially had the SBC wires reversed so nothing worked on the first try but once I swapped them, I was able to open the gates successfully.
Issue is that I have HA has no indication of whether the gate is opened or closed. what do i need to do next?
edit: I answered my own question. I needed to toggle on the 3rd dipswitch for each aux relay because i have two actuators.
Thanks to all that contrtibuted to this excellent thread. Following along made this modification much easier than it otherwise would have been.
