Simulate a push switch


I’m trying to automate my electric garage door opening/closing. It has a push button microswitch which if you push and release will open it/close it. Hence I was looking to use a relay (open to other ideas) that could be wired in parallel to the switch and act as a momentary short for half a second; there can be no power on that circuit.

Any ideas on products and how to wire them that could work? I was thinking about using a Fibaro Switch but wanted to reach out the the community on thoughts.
