Nest Protect Review


Nest Protect

Back in January, we bought a Nest Protect smoke and carbon monoxide alarm (Amazon link). Like other Nest products, it’s a smart, ‘internet of things’ device, so it does a bit more than your regular cheap alarm.

For me, its two best features are:

  • Push notifications to your phone when the batteries need changing, rather than random chirping at 2am
  • Being able to cancel an alarm if you’re accidentally burnt your sausages but have the situation under control

Set-up is easy; it’s done through the Nest mobile app before you attach the alarm to the wall or ceilling. We went for the battery-operated model, but you can also buy a mains-connected device if you have the relevant wiring in place.

The Next Protect has a small motion sensor (like the Nest Learning Thermostat). If it’s in a dark room and detects motion, it’ll briefly illuminate with a white light. The light will also glow red, yellow or green depending on whether it has detected any issues.

There’s also a small speaker and a microphone. As well as an alarm tone, the Nest Protect will talk to you to tell you that it has detected smoke or carbon monoxide. The microphone is for self-testing; periodically, the Nest Protect will have a ‘drill’ to ensure that it’s working correctly.

Nest products work together, and as we have a Nest Learning Thermostat, the Nest Protect will tell the thermostat to turn off our central heating boiler if it detects carbon monoxide.

Before buying the Nest Protect, I considered the Roost smart battery (Amazon link). Roost works with your existing smoke alarm, but adds some of the smart features. Unfortunately, as it’s slightly larger than a standard 9-volt battery, it doesn’t work with all smoke alarms.

The other factor that convinced me to buy the Nest Protect was an offer that was running at the time: free delivery and a free Google Home Mini. I’ll be reviewing the latter in another blog post.
