Is there any other smoke + CO alarm besides Nest Protect that is not Z-Wave?

Hey,

I'm looking for a smart smoke + CO alarm (I don't want two separate alarms) that is preferably battery powered. Google Nest Protect is commonly suggested but the ha-nest-protect integration seems a little clunky with its cookie authentication method. I would like something more reliable considering the alarm's purpose (and for the same reason I'm looking for a certified alarm). I also know First Alert makes a Z-Wave combo alarm but I don't have a Z-Wave network and not planning to establish one, my options are either Zigbee or WiFi.

Unfortunately I am not able to find an alarm that would meet my requirements. Are you guys aware of any options?

Thank you!
