This is what I do. When we are away, vacation and at night. I kill the power from my old garage door (chaimberlain) and it has been super reliable ever since. Have paired it with a Zooz relay and SmartThing garage door tilt sensor and have love every moment of it.
Only complaint is once every 8months-ish I have to replace the tilt batter since it also reports the temperature in my garage.
