Hard Wired Smoke/CO Detector

I love that Ring works with First Alert's z-wave smoke/co detector, but unfortunately those are only available as battery-operated. It's great because I was able to easily add them to additional places in the house that weren't wired for them. However, we do also have wired units in place. If Ring offered a wired option it would add a degree of safety since you're not at the mercy of a depleted battery. You could also add things like a nightlight and push notifications for low battery that just aren't realistic in a unit that runs on 2 AA batteries. Shoot, go ahead and make them a repeater for other devices on the system since you've got power anyway.
