Google - Nest Protect 2nd Generation Smart Smoke/Carbon Monoxide Wired Alarm - White

First let me start by saying I highly recommend this product. Long story short I had a fire in my home. The nest worked and alerted me while I was away from home. I called the fire department when I noticed the temperature on my nest thermostat rising. We lost everything inside mostly due to smoke and water damage. The fire chief said had we called any later the whole house would have been gone. I will be buying these again. Tldr buy one you won't regret it, and do not ignore the alerts.

I am sold on these. We had one at our old house and had to get them in or new house. These are easy to set up and manage through the Nest app. They are not to sensitive which helps to eliminate false alarms, and when an alarm goes off the notification is sent. One of the great additional features is the lighted ring that illuminates when you walk past. We have these set up in hallways and it's nice to have a little light at night when hall lights are off. I would highly recommend to anyone looking to looking for a smoke/Carbon Monoxide detector in a smart home setting.

I love my nest protect wired smoke/carbon monoxide detector. It actively monitors and communicates. Also performs self-checks. Absolutely perfect.

Great addition to Nest home system as motion and light for basement

We are trying out the google smart home and gotta say these are pretty cool additions

Work perfectly. Great Design, Quality & Operation.

It's a great product. If it does alarm it tells you which one is alarming (if you have more than one). They talk to each other on their own secret network, so they work even if your internet goes down. And the wired unit has a battery backup if the power goes out. It even does self checks. Oh, and it's a night light.

My family already had one in our main level and wanted to add two more so each level is protected. They installed easily and connected quickly to the Nest app. This product does a great job at keeping us protected. I highly recommend these over your traditional fire alarms.
