Best HomeKit smoke and CO detectors iMore 2021

When you're at home, it's important to have a smoke and carbon monoxide detector in every room, just for peace of mind. But if you have other Apple HomeKit accessories and devices in the house, it's worth picking up a smoke and CO detector that also integrates with HomeKit. That's because you can get notified on your best iPhone when there is smoke or carbon monoxide in the house. There aren't many of these products on the market, and they usually go in and out of stock regularly, so we recommend signing up for email alerts when they are back in stock. These are the best HomeKit smoke detectors that we have found so far.
