I need in install 6 smoke alarms in my house addition. 2 bedrooms and 1 hallway upstairs, 1 bedroom and 1 hallway downstairs, and 1 basement near the oil boiler. I’d also like to connect these to 5 other alarms on the old side of my house where there are currently only battery powered alarms. I’d like to be able to get alerts on my phone if I’m not home. So far I have a mishmash of smart products such as Lutron Caseta switches, Wyze plugs, and lorex cameras so eventually I will have to get home assistant or something to integrate everything into apple HomeKit.
I feel something like google nest protect will get silly expensive. I’m wondering if I can just get all standard kiddie hardwired alarms and only smart kiddie alarm to get notified if any alarm gets triggered?

These are “interconnected” using RF which is now acceptable by code at least it’s when I checked with San Diego Fire Marshall. But YMMV. SD has interconnect (only within each apartment) and dual-power requirement in high-rise dwellings.
If there’s an interconnect dongle for old hardwire-connect detectors, you’d find it on/linked from above link.
They all have a 10 year mandated lifetime anyway. Maybe just replace all now?
