I have zigbee contact sensors on my garage which tell me if it's open or shut. That works well. I have two, just in case one messes up.
I have a zwave dry contact switch wired into my garage door opener. I link it to some Hubitat web end points in this video. In the past, I opened the garage door on presense, but as you mentioned, it's not reliable enough, so I dont do that now.
The garage door switch is linked into google home (as a light switch), so I just say "Hey google, turn on the garage door" (either in the car approaching, or in the house walking to the garage). Works very well, for 12 months or more.
