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.

Can these work stand alone to send alerts to my phone/email?
Is there any other home automation that is designed to listen for dumb smoke alarms? I do not have a central hub smart system though.
"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. "

Too bad Wyze doesn't support z wave. I still went ahead as price is great and at some point I will have to change the monitoring service.
Any idea

*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.

As for the these detectors, I have the 1st gen and never had a nuisance alarm. Also most CO detectors, including these, are not sensitive enough and only sound the alarm at CO levels 70 ppm or higher for an extended period of time. If you really care about CO detection, buy a Low-Level Carbon Monoxide Monitor and place near the water heater and/or furnace but more than 15 feet away. Those aren't cheap, however. Expect to pay $100-200.

Similarly, even though most of the smoke rises up to the ceiling, some of it spreads to the floor, just less concentrated.
TL;DR: one of these ceiling mounted on each level (preferrably inside bedroom and near mechanical room) is plenty of coverage.
