Home automation is the residential extension of building automation.
It is automation of the home, housework or household activity.

The Meross is just a relay with wifi, so you would have to figure out whether you can close/open the door through one of the terminals. The terminals on the left are the high-voltage side, so I would not touch those.
You could try putting a jumper between terminals 19 and 20 which is the push-button connection. If the door opens or closes then you just attach the two wires from the Meross device to those terminals. If that does not work, you may need an attachment to the Meross unit or something else entirely.
Here is the wiring diagram for that opener - https://irp.cdn-website.com/cff40d41/files/uploaded/RD20X2TELL.pdf You should be safe connecting terminals 19 and 20 since those are low-voltage connections, but if you are unsure maybe talk to someone who knows more about those specific garage door openers.
