I have a variety of Shelly 1 devices in my house, one of which is on the oldschool Garage Door opener (with a reed switch for open/close tracking) - Very inexpensive, flexible for other applications, and works with HA etc.

The Shelly Uni is the correct device to use for these applications:

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.

Huge fan of shelly. I wrote a little sinatra web-server that can just show the current state, and toggle the state, of a bunch of lights around my yard. I really appreciate that all you need is http, no cloud, no fuss to just put together a custom ui for them. Couldn't recommend them more highly
