Re: Auto-Open Garage Door when Carbon Monoxide levels too high
If you can install a system for your basement, you can install the same system in a garage for carbon monoxide. (and if you're that concerned about power failure, get a whole house generator)
OR... just install a fan in your garage on a timer. Schedule it to turn on and off intermittently.
