Any solution for my gate & garage rolling door?

There are usually two different approaches for this kind of situation, although I’m a little uncomfortable from a safety aspect about trying option one with a garage door. It should be fine for the gate, though.

  1. add a relay with a momentary capability and essentially just hotwire the device. You didn’t say what country you are in, but if you are in North America the smartest House makes a good Z wave one on that frequency.

Their customer service is very good, so you can contact them with questions.

Some people will hotwire the button remote, which is probably the safest approach, although it may also be possible to hotwire the controller unit itself.

  1. Use a battery powered actuator, essentially a “robot finger,” to literally push a button on the remote. This has the advantage of not requiring any wiring and maintaining all of the existing safety features on the system. I use these for several applications in my own home.

Switchbot is a readily available Japanese brand that you can get from Amazon in either the US or the UK. It has an official integration with smartthings which works pretty well. You do need to also get one of the “mini hubs“ which is how you get the integration.

The biggest drawback on these is the cost. You will need one button pusher for each button, so if you have four or five buttons that can add up. But it is a good way to solve the “last Mile“ issue when retrofitting many devices

Here’s a recent review I did of the device:
