Nest Protect Smoke and Carbon Monoxide Alarm - 2nd Generation (Battery): Nest Protect reliably detects and alerts you to the presence of smoke or carbon monoxide in your home. The alarm speaks to you in a calm, clear, human voice, telling you the location of the danger. It also provides smartphone alerts and battery status updates to help protect your home.
Protect your loved ones and your home
Detects levels of smoke and carbon monoxide within the home and tests itself automatically.
Receive clear direction in an emergency
Alarm speaks to you with a human voice and tells you the location and levels of smoke or carbon monoxide when they are present.
Send alerts to your smartphone
Provides battery and sensor status notifications so you're always informed, and safety history so you can see what happened over the last 10 days. You can even silence the alarm from your smartphone.
Get an early warning signal
If a cooking mishap leads to a small amount of smoke, Nest Protect will let you know without setting off the full alarm.
Stay on top of any situation
Synchronized sensors ensure that when 1 alarm senses danger, every alarm in the house will make you aware of the situation.
If carbon monoxide is present, Nest Protect links with your Nest Thermostat (sold separately) to automatically turn off your gas furnace.
Light your path at night
Pathlight illuminates your way in the dark. Adjust its brightness, leave it on as a nightlight or turn it off from the Nest Protect app.
A:AnswerNo. What you and I are looking for is a hand held something that detects secondhand smoke in our units, or something a property manage can use to inspect. I have severe asthma and COPD and am in a “non-smoking” building. Ha ha. Their is something called, Air Guard that has been built by a Dartmouth professor that is a sensor in the smoking units that detects and alerts a manager via the internet. It sells units and a program far beyond ordinary tenants income and access. I’ve pleaded with them to release a hand held device, but to no avail. Wouldn’t it be nice to have something that plugs into your phone that does this?
A:AnswerNo, however, you will not get notifications via smartphone if it's not connected the the Nest app. The purpose for a "smart" fire/CO device is to alert you when not at home via the app. In addition, it has other feature like automatically checking the devices batteries and sensors. The device will always alert you locally with an audible alarm for fire or CO, even without WiFi/internet.

A:AnswerYes, you can schedule a time/day for the self check in the app and you can set it up to remind you that it's supposed to happen, and even cancel it. The self check seems to be the alert tone and the voice, but I haven't been home for it yet. All of the devices self check at once.
A:AnswerI have 6 Nest protect alarms and I also have 5 Alexa devices. I don't feel that I'm missing any functionality with the Nest Protect and also using Alexa. One downside, although in my opinion, fairly minor is that you will need to download the Nest app to setup and maintain the alarms. The Nest Protect devices and the Nest app work really well together and enable the full functionality of the devices. You get alerts on the app no matter where you are ( as long as you have internet access) if an alarm sounds. Can also silence the alarms or get a notification if the battery is low.
A:AnswerIt isn't about square footage when it comes to smoke detectors. It is much more about layout. You can look up what codes are in your area, but generally you are supposed to have one in every bedroom (to awake anyone sleeping) one outside of every bedroom(s) or in other words the hallway to detect smoke or co if the door is closed. One in the garage since this is a common place for co and fires. One next to the kitchen area since this is also a common place for fires. One at the top of your stairs to pick up smoke rising from the basement, and one next to your utility room since the is a common place for co poisoning. If you can combine these areas and grow your square footage coverage great, like putting one at the top of the stairs right next to the kitchen. However there are building codes for a reason, your safety, so if in question, follow those.
A:AnswerYes, interconnect works on battery version and does not require WiFi once it is setup. From the Nest website:
"Once it is set up, Wireless Interconnect will work even without Wi-Fi in your home, since it operates on a different wireless protocol to connect all of your Nest Protects.
Nest Protect Wired (120V or 230V) and Nest Protect (Battery) are compatible and can interconnect with each other."
