I agree the splicing can be difficult. I also have a hard time dumping $96 for a garage controller, especially for a garage door opener that is 10+ years old. Most garage door openers have 15-20 year lifespans.
You can purchase a new garage door opener for ~$150 then an internet gateway for another ~$40. Installing a garage door opener is not too bad, took me a couple hours and no high power electricity. Currently rocking the liftmaster with gateway and pretty happy with the smartapp integration into SmartThings. I still use a tllt sensor.

There are several different routes you can take with this. Using a tilt sensor asking with the relay works. The problems I’ve seen are the door getting out of sync. But now that I think about it, most of those issues were with people using the Amazon echo.
I went the route of the nutone because it was cheap, had good reviews, comes with its own tilt sensor, and works great with my genie door controller.
It’s only a few bucks more than what you are going to send anyway, so I thought I would offer the option.
The “real” garage door opener is definitely a better solution but you can automate your garage door with the two devices. It will still look like 2 devices in SmartThings but it works and is the cheapest option. I have it installed and never had any issue with it for over 2 years now.
Setup is easy. Just follow instruction for the FS20Z-1 and connect it to power (you will probably need to buy a power cord and a electric surface mount box, total ~$10) and to the existing garage door opener (parallel to your remote/switch) and pair with SmartThings. Then change the device type to “Z-wave virtual momentary contact switch”… Done!
There are some more elegant ways of implementing the 2 devices (search the forum for updated device types/ apps) but this has been working fine for me. I usually don’t use the SmartThings app to open/close the garage door. So having two devices instead of one does not matter to me. I normally close/open the door as part of a routine, a button/widget on iOS Today, or via Homebridge/Homekit/Siri.
what am I looking for. I searched electric surface mount box at Home Depot and it brings a lot of stuff but not sure what I need. Also where my opener is mounted there are 2 plug points, one used the opener and I guess I can use the second one for the relay switch?
