The safety and efficacy of this device will be determined once it is in widespread use in multiple settings. Just the same would not recommend charging youe EV in an attached garage while you and your family sleep.
You really shouldn’t charge in your garage. Park it in mine instead. And leave a key in case I need to move it out of the way. ;)
