… titan water valve actuator automatically closing when a leak sensor detects a leak, ratgo garage door closing at night incase I forget to close it, zoos zen55 co2/smoke detector and an automation to send me an email incase it detects something. Probably my biggest ones.

Z-WaveWorks LocalTaps hardwired smoke alarm interconnect to report smoke or CO in HA

Obvious shill post but i'll bite. DO NOT buy any specialized smart smoke equipment. Use your already linked dumb detectors that are already installed in the correct/compliant places and just buy a relay like Zooz ZEN55 detector bridge. It can piggy back on your existing system and notify you when either alarm goes off. Spending a bunch of money on something with an expiration is not necessary. Home Automation can be a hassle sometimes and there's no reason to complicate these alarms. Ever have to re-pair or troubleshoot a smart device? Great it's on the ceiling.. Who needs extra sensors and …

Z-WaveWorks LocalWired to Kidde detectors; 2 users happy, industry-standard alarms for insurance
Saved copy
A Zooz ZEN55 Detector connected to traditional smoke detectors - in my case Kidde wired w/battery backup. I would MUCH rather have an industry-standard smoke detector that my insurance isn't going to turn it's nose up at if (god forbid) I ever have a fire. Super happy with this setup!

Z-WaveWorks LocalPairs with any dumb smoke detector; warnings triggered through HA entities
Saved copy
Any dumb smoke detector connected with the Zooz Zen55. It's about as close as you can get without pathway lighting. You can set up the warnings through HA using the Zen55 entities for triggers.

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
