I am putting automation for the door but only to make sure when I arm the alarm and leaving the house, that it is closed for sure.
As far as your finger is concerned.. it could happen if the same situation occurred and another member of the household was on their way home, triggered the opener with the remote from their car shortly before getting to the house - and not actually seeing if the garage door was already open, or if your finger was on the track. This is a standard feature :-) If anyone is standing with their finger in my garage door track when I go to bed - they deserve to lose a finger.
As far as long hair, if you are standing around the garage door, and your hair is long enough to blow to 7-feet into the air to where the door's wheels are when it initially when the door is all the way open - you must have a 7' tall wife, whose head is also resting on the door. If you are generally standing around it, you would have plenty of time to move before any hair gets pulled from your scalp, unless of course they braid their hair into the track - for this situation, same as above.
For HA integration, throw a CCTV camera into the garage as well, and check it before you hit the button remotely. Unless you just dont want your wife to have access to what you are REALLY doing in there :-)
Another possibly cheaper solution, would be to add a warning speaker and message which is activated when the button is pressed, warning anyone in the garage to move away from the door. Also have the signal to the garage opener delayed for XX seconds until after the message is done playing.
Without a camera how do you know the garage door actually closed by your remote input, and the signal wasnt missed? Without watching a live feed of this, someone could potentially jump the Line of Sight sensors and enter your garage as the door is closing, and you wouldnt know someone is inside your garage and possibly your home.
Obviously there are endless cases for most any HA situation, but as far as the garage door integration being safe, I dont think anything dangerous could occur by integrating this than what could happen with the standard remotes that come with the opener.
