Listening for Garage Door Remotes with ESPHome

We are renting a house that has two old garage door openers. We have a switch by our front door that controls the garage doors. I think the landlords or the previous tenants lost the garage door remotes. We received two remotes when we moved in, but I couldn't get them to work, so I think they bought the wrong replacement remote for one of our doors.We have a Merlin M230T garage door opener, which is an older model sold between 1996 and 2001. This one uses DIN switches to configure the security code:It looks like the landlord or a previous tenant bought a newer M842R remote that uses "rolling codes" for security. This remote is for garage door openers made between 2001-2007.We needed an M802 remote for our old garage door, but a replacement remote costs $100.Two-Button Remote Control M802R (Blue Button) | Merlin AUEnhance your garage experience with the Merlin M802R Remote Control to conveniently support multiple legacy opener systems.
