The First Alert OneLink Wi-Fi Smoke and CO Alarm offers similar functionality to the Nest Protect. The hardwired version costs $120 (£80, AU$165), or $110 (£75, AU$150) for the battery-powered alarm. And since this First Alert is compatible with Apple’s HomeKit, Siri can check the status of your alarm.
