Smokealert is selling their combination Carbon Monoxide - Smoke Detectors for $38.95 with free shipping. Mine didn't ring up with tax. I've seen it go as low as $30 in the past, but it has been a long time

Product Description from site:
Z-Wave enabled battery operated photoelectric smoke/CO combo alarm. It will NOT WORK with the Onelink System! It is compatible and will link the hubs from Nexia Home Intelligence, Iris Smart Hub, and other Z wave technologies. BRK ZCOMBO-G has been fully tested and complies with, UL217, UL2034, CSFM, NFPA 72, NFPA 720 and NFPA 101 and other agencies that model their codes after the above agencies. It meets building codes where battery operated Z-Wave wireless smoke and CO alarms are required along with silence features and with model building codes published by the ICC.

BRK ZCOMBO-G is a state of the art wireless combination smoke and CO alarm designed to provide early warning of a fire or CO. It features a fully insect screened Photoelectric smoke sensing chamber and an electrochemical carbon monoxide sensor, an 85dB horn, a supervised 3V (2 AA batteries) power supply, a full function test switch and a silence feature. This combination alarm will operate with 3rd party, certified Z-Wave devices and the basic command class required by all Z-Wave devices. By the requirements of the Device Class spec, this command class does not have to be mapped to any particular functionality for this device. The alarm supports one association group with up to 1 node, and sends its alarms to that group. The alarm supports configuration parameter #1, which has a size of 1, a default value of 0, and when set to 1 causes the device to send double alarm messages.

It also features tamper resistant locking pins that lock alarm to the mounting bracket and battery drawer to prevent removal of battery or alarm. Perfect for apartment, dormitory or hotel applications. Designed for wall or ceiling mounting. Includes mounting anchors and screws.

Not that slick. Amazon has this normally for $44, so this is saving $5 off a regular Amazon price.

Not a need-to-buy-now deal IMO.

Bummer that this can only run from batteries, which despite their claims will deplete very quickly (not only monitoring for smoke/carbon monoxide, but also constantly sending Z-Wave signals). Would have been so easy for them to add an AC line feature. Kills the value of this product.

I ordered 3 from them about a month ago at the same price. It was the best price per unit I could find at the time, even considering Lowe's 10 off 50 or 50 off 250 (which obviously adds tax). They shipped them via Priority 2-day for free.

After one month my battery levels are at 96, 94, 93%. They use AA batteries so you can use rechargeables. I plan on using Eneloops when the included Duracells die. But I do get how it would be inconvenient to change them more often than usual. The backup 9Vs in my hardwired detectors last about 5 years.

I've had these for 2 years. The batteries are fine and don't deplete very fast. You can also monitor them with whatever hub you have and replace as needed.

The big problem is that I got frequent false alarms with them and decided to stop using them where I got notifications. They work well as normal smoke detectors as I check them a couple of times a year with the smoke test.

However too many false alarms for something that when it notifies me it should be a real issue.

How do you know it isn't a real issue?

So this will not work with their onelink system, but if you have multiple then they are in a mesh zwave network, so will one going off not set the other one off, is that something you would have to configure on the software side? I want to get one that is dual power/battery where possible, but interested to know how the interaction will work regardless. A while back I was about to replace all my existing detectors with dual sensors onelink models and then use something like this to tie it in to the z-wave system to call out for the fire dept...

Has anyone else done anything like this?

I just bought 40 Kiddo combination smoke/carbon monoxide detectors with AC and 10 year lithium battery for $32 each. They aren't ZWave but honestly, who gives a shlit about that? Nobody is checking their phone for smoke alarm status. I own a few apartment buildings and even I don't see any value in that function.

A for effort, but the lack of hard line or lithium battery kills it for me. Changing batteries every couple of months is annoying as hell, even for a personal home. Get the 10 year systems and thank me later. Alkaline is dead, boys; get on my level.

You don't check your phone from time to time for alarm status, it push notification and text you when the alarm is on.

I'm speaking more toward the status of the alarm with regards to battery replacement. That's the number 1 pain in the ass with detectors, and with a combo device such as this and a lack of hard line connection, you'll be checking and changing all the time. PITA

It would be the same as a non smart detector. It beeps when the battery is low. As a good habit, one should change the battery twice a year for all smoke and CO detector before even the battery went low.

Actually, the batteries last quite a while. In addition, I can check the battery state of all of my battery powered Z-Wave items from my smartphone or PC anytime I want. If I have a detector with lower % I can simply replace it... on my schedule... before it ever beeps once or goes dead. No more frantic 3:00am (do smoke detectors ever die mid-day?) battery replacements for me thanks. Cool

"quite a while" is a subjective descriptor. If I have to change more than 2 times a year, then it is too long. Also, the cost of 9V or AA batteries adds up. For example, I just bought 40 Kiddo combo detectors for $32 each. They don't have ZWave built in, but it's fine since I don't have to worry about them for a long time. I simply don't see the value in having a status on the phone over not even caring about the status since they are good for 10 years.
