Smoke detector

I'm having trouble adding mine to my ring setup. I'm holding the add button as I close the battery slot but the hub never finds it. Did you do anything different?

I figured it out. I had to reset the unit first by holding the button until I got 1 beep and then a second long beep. Once you do that it will pair when you follow the pairing instructions.

although I don't get the point of this because I believe that carbon monoxide is a heavy gas and stays close to floor, I would rather have it lower.
Even if CO were heavier than most air components, it is typically a combustion by-product so it is almost always hot and would therefore rise.

I wonder if Amazon ship these to New York because these kinds of alarms with removable batteries are banned in the state.
Someone else posted the link to the NY law.

Detectors with radios (ie the zwave part) are exempted, as long as you connect them to an alarm system or other monitored network. Meaning in NY these need to be tied to a zwave controller that notifies people of an event to qualify. You can't just stick these up and not have a zwave controller and still be compliant.

If you use it with ring alarm, do you still need smartthings?

We bought these a few months ago. While they are great and all, we've had two false alarms due to dust on the sensor. Both were within a few days of each other, turning on ceiling fans and the such...they are very sensitive.

Many CO deaths occur without fire. A combo detector is an inherently flawed design.
… I'm not really sure what you're getting at. Combo detectors alarm for either condition, they don't require both to go off. These will sound for just CO. And the ceiling placement is fine for CO detection.

You are confusing CO2 with CO. CO2 is generally not harmful, even at many times the concentration found naturally (400ppm).
No confusion. We are talking CO.

CO2 is heavier than air. If you have CO2 up to the ceiling aren't you dead already?

Just a friendly PSA from a fireman, please make sure you have enough smoke alarms and carbon monoxide detectors, many people also dont know they go bad, so if you have them already take a look on the back of them they will have an end of life date, if it's close replace it please.

These things and keeping bedroom doors shut while sleeping are some of the best things you can do to help in the event you have a fire, and carbon monoxide kills people far more often then you would think based on the news, don't let it happen to you or your family.

Looks like a pretty good deal, even if it's not the best it's ever been, if it's time for one you should just be getting it not waiting around for a better deal, it only takes one bad day.

Sorry off my soapbox
Thank you for your Post

Was confusing the value, sure, but the question still stands.

If CO is heavier than air and you're detecting it at the ceiling... wouldn't you be dead by the time the alarm goes off?

Would it work with any general z wave hub then? I have frontpoint alarm system so would like to add more to our home. Tia
Works great with my Smartthings Hub.
