Description

The Kidde Smart Carbon Monoxide Detector & Indoor Air Quality Monitor uses electrochemical sensor technology to detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm with a voice alert announcing "Warning! Carbon Monoxide!". The Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet and provides battery backup in the event of a power failure. The lithium battery backup lasts the full 10-year life of the alarm, so you'll have the benefit of never having to replace a battery. Up-to- date, real-time notifications are provided through the Kidde app, so your family & friends - even the pet sitter - can monitor your home's air quality & receive alerts to CO presence, high humidity levels that can lead to mold, unexpected high or low temperatures, or Total Volatile Organic Compounds (TVOCs). Setup is easy: simply download the Kidde app, scan the QR code at the back of the CO alarm, & plug the unit into your wall outlet. You can also use voice commands to check the connection & status of carbon monoxide or air quality by pairing it with your Amazon Alexa, Google Home, and select iPhone & Android smart devices. A digital display screen on the plug-in carbon monoxide alarm provides real-time information on the status of indoor air quality and carbon monoxide levels. Two buttons are provided for easy accessibility: the Test-Hush temporarily silences nuisance alarms, tests if the unit is operating properly, and silences a low battery or end-of-life chirp (up to 24 hours at a time for a maximum of 7 days), while the Peak Level Memory Button records the highest CO level reached since the button was last pressed. Install a smoke detector on each level of your home and inside and outside each bedroom. UL Certified with a 10-year limited warranty (not a battery performance claim).

    • Quality Kidde Device
I own a slew of Kidde devices, and I decided to add 3 of these to my collection. I got all three of them set up in less than 10 minutes. I'm using them to monitor the air quality and temperature in three different rooms. So far, so good. They're working like a charm. They seem a little pricey, but when you consider what they do, you'd come to the same conclusion as me that these are essential for keeping your family safe and healthy. ... show more

    • Fast and easy to setup, love the air quality monitoring too
After adding the smart smoke detector, I added one of these on each floor of our home. Even with other CO detectors its great to have these paired to my phone in case of an emergency. Having the air quality monitoring is a nice addition to keep track of humidity and air quality on each floor. Great product! ... show more

    • Great CO and Humidity sensor, unknown accuracy on VOCs
Easy to install and overall great humidity and CO sensor. I'm unconvinced of the VOC accuracy. I've done so many experiments to check why there are spikes in the VOC reading during my kids bedtime. I've tweaked lighting, temperature, flushing the room with air, occupancy, I've removed every cleaner and solvent from my house, etc etc. The only thing that has been consistent is that when my two year old goes to bed - the readings pop up to 600 ppb VOC. Is it just people breathing in the room? Seems like a potential error from a low cost sensor. Would love to hear more from Kidde on the accuracy of the VOC sensor. ... show more

    • UPDATED:Still trying to set up wifi...
I wrote the review below after having spent a hour trying to connect the Wi-Fi. After trying yet another hour, with no success, I packed it up and returned it this morning. We have a smart home, with several kitchen appliances, door locks, lightbulbs, Amazon devices and doorbell. We have fast Wi-Fi with lots of bandwidth, and it’s very unusual that there is a problem connecting to Wi-Fi on either the 2.4 or 5 network. This product had a card in it saying it was easier to call for assistance than return it, but that’s actually not the case. There are too many other good products out there, making it useless to keep trying to make something work that just doesn’t. BTW, it works only on the 2.4G network, which has always been the easiest one to connect to. Original review, at first giving 3 stars across the board: Today I bought an Amazon IAQ monitor and this one. I'm mainly concerned about VOCs since I have a pet bird, so I got 2 relatively well-rated devices to compare, and ensure that they are both properly monitoring. The Amazon device set up very easily, and I like the interface. This one I've been putzing around with trying to connect the wifi for the past hour or so. If it times out yet another time, I'll be returning it. I will update this review when I know if I will be keeping it, but so far it seems to be more trouble than it's worth. ... show more

    • Helpful alerts
When I was buying this, I thought its features were probably an overkill and we may never use all those. But it keeps sending various alerts about VOC levels and other air quality alerts to my iphone. It prompts us to open windows and keep indoors healthier. It even alerts us when it has lost wifi connectivity so it acts as an alert when our wifi is down :-) ... show more

    • Works well and easy to install
I made the hard-to-believe mistake of leaving my car on in the garage and it spooked me so much, that I decided to install a CO2 detector that can alert me if my garage fills with high levels of exhaust fumes. Fortunately, it hasn't gone off since I installed it and I hope that it never will (I'm assuming it works). Believe me, it's not hard to forget to turn off your car, especially with button type ignitions and quiet idling. The detector also senses high temperatures, which I suppose could be useful, but in my case, I live in Florida, so my garage is always hot. ... show more

    • Constantly Disconnects From WiFi
Great product when it works. I have very strong wifi and use devices in the room where the detector is located frequently with no problems (have also tested the wifi up/down in that room), but the detector is off 70% of the time. Sometimes it will reconnect, but not after being off for an hour or more; otherwise, I have to unplug and then re-plug it in for it to reconnect. ... show more

This is a great product particularly if you need to monitor things remotely. The air quality sensor is a particularly useful feature.
