It can be powered by 12-24V DC or AC, so you can power it off the accessory wiring of the device. It has two relays to control two different actions (my gate has a secondary partial open mode, to walk through it without opening all the way), and has two digital inputs to monitor state of the device (my gate exposes an "is open" and "is closed" state).
The setup in the app is a bit confusing though. Well the app seems like it was designed by a Unix neckbeard, but it is very powerful - I haven't needed to switch to MQTT/Home Assistant to do the automations I want.
My devices can be triggered by a momentary switch: press and release to open, press and release again to close. The app has a "Momentary" switch type, but that did not work for me. I had to use "Toggle Switch" then set a auto off timer for 0.1 seconds.
