Don't want to poop poop on the deal, but you can make your current existing interconnected smoke detectors Z-wave smart. The Zooz Zen 55 can be wired into your existing interconnected smoke detectors and will send notifications for Smoke/Fire and CO. I used to have a different solution that used modules and open and closed switches, but switched to Zooz and it's been working great.

Same with SmartThings 👍🏻
Edit: Maybe not. ZCOMBO model works great with ST. These are the replacement (SMC0410) and may require the V3 ST hub.

Pretty sure I got a three-pack for a Benjamin a couple of years ago, but those were different times.
Still flogging my old Vera, and they work with that. Have what I need for HA, but I keep procrastinating on that struggle ...

Based on this thread, it looks like it would work fine with HA: https://community.home-assistant....0/903536/3

The biggest difference between this 2 pack and the older 3 pack we'd see for about $100 in the past is that these have the 10 year battery built-in (which is nice as these units should not be used beyond their expiry anyhow).

To work with Smartthings, I had to upgrade my v2 hub with the v3 hub

Looks like they've extended the service life to ten years also, rather than the seven years before.

the first generation of these were finicky and needed a custom integration in HA. they are starting to go bad 7y later (they beep constantly, no amount of resetting will stop it, when they are EOL). been slowly replacing them with these newer ones that work out of the box. don't need any at the moment but may get a couple spares anyhow.

Can these be silenced from your phone? Do they communicate with each other? One of these days I'll have to replace my now discontinued Nest smoke/CO detectors.

As others have mentioned, with SmartThings you need a V3 hub. I have a V2 and was pulling my hair out trying to get these to connect until finding out that they wouldn't work.
