I don't know why this thing exists.
Now hang on, I know why smoke detectors exist, but specifically I don't know why Roost made the Roost smart smoke detector.
I had high hopes for this thing.
This is the company behind The Roost's smart battery, which I really liked.
And I thought the smoke detector would up their game and compete with Nest, but it doesn't.
This Roost costs 80 bucks.
It detects smoke, fire, carbon monoxide, natural gas.
There's also a $60 version of the same thing that just does smoke and fire.
Both of them are hardwired with a battery backup.
But even though this is called a smart smoke detector, Literally nothing is smart about the smoke detector itself.
All of the smarts come from the battery.
So if you have a dumb smoke detector, you can do everything this guy can do just by buying that $35 Roost 9 volt.
So if you need a replacement detector, this is a fine buy.
It worked well in our test It's just not as smart as the [UNKNOWN] Protect and not as affordable as the Roost smart battery on its own.
