Obviously, if we visit your home twice a week because of this, we'll want to have a conversation - otherwise, my statement stands
I have 7 of these and they are VERY prone to misfiring, usually at the late hours of the night/early morning. I've replaced 4 in the past only to find out that a can of compressed air usually solves the misfiring. If you read the reviews there is a consistent pattern of this.
I run these in HomeKit via Homebridge. In hindsight, I would avoid these and go with a standard smoke detector from Costco.

They didn't update the model number, and there really isn't any mention of the 1st gen on their web site. All instructions are for 2nd Gen, though they mostly avoid any Gen references.
Check the dates of any info. Anything after about October 2019 is 2nd Gen.
I think the only difference is in the Z-Wave chipset. The Smoke and CO sensors are the same.
These documents had the only references I could find.

From the second page:
Note:
The 2nd Generation ZCOMBO has a year of manufacture of 2020 or later and has a QR code printed on the back of the alarm. If your alarm does not have a QR code, skip to the next section for 1st Gen ZCOMBO pairing steps.
Here's the 1st Gen manual: https://data2.manualsli
I think the 2nd Gen will be a much better Z-Wave experience. I'll be buying these in a couple of years when my 1st Gen reach EOL.

*Smoke rises--it will fill the room from the ceiling down, so you should position a smoke detector near the ceiling.
*Carbon Monoxide (CO) sinks--it will fill the room from the floor up, so you should position a CO detector near the floor.
Putting those two together, there is no way to position a combined alarm so that it is optimized for early warning in both cases. And the whole point of these alarms is to get as early a warning as possible. I suppose you could position one near the ceiling and another one near the floor, but it would probably be cheaper to get a smoke alarm to put near the ceiling and a CO alarm to put near the floor.
If you have a hub that works with zwave plus, i'll pay you to get this new set, and you can give me your old ones

Similarly, even though most of the smoke rises up to the ceiling, some of it spreads to the floor, just less concentrated.
