Smoke/Co detector recommendation

[BillConroy]

I have been attempting to research a smart wired smoke/co detector. It appears from the research there aren’t any devices that are wired US mains, capable of sending out notification so I could trigger an automation.

The automation I want to create is to shut down 2 HVAC system upon notification of alarm and turn all interior lights on. My HA instance is new being put in to replace an obsolete HAI Omnipro installation. Only devices installed so far include are switches, plugs, and thermostats integrated to HA through hubspace. I am open to any local protocols that can run the automation by HA. If I can find a smart wired/battery backup detector with an interface to HA that can send out the alarm I would add the hardware required to get signal to HA. I have 11 Nest devices that are reaching their 10 year limit in next 60 days so I would like to find something pretty soon but could wait if folks know of anything about to be released. It seems there may be some devices using matter protocol but I only have found rumors. Any suggestions to look at would be appreciated.

I have 2 of these Z-Wave Ecolink listeners that are mounted within 1ft of existing wired dumb smoke detectors. I have performed multiple accidental tests of detector near kitchen and the Ecolink has detected the alarm 100% of time.

I found out recently, that my apple homepods detect and send alerts to my phone when the smoke detecter went off.

I hope this thread will be result in a mains powered Matter smoke alarm with wireless interconnection to other alarms.

Heiman zigbee and matter smoke alarm proposal

Dear Matter, Zigbee2mqtt and HA experts and fans, This is Leo from Shenzhen Heiman Technology Co., Ltd. we started a new team to focus on the experiences for DIY users, we’ve got a lot of feedback of adding more functions to our smoke alarm, like the mute alarm, remote test and interconnection, etc, and now, here we are … we are going to start with our zigbee smoke alarm which model named HS1SA, if you guys love it, we will do these updates to more models of our smoke and CO sensors. including…

If it comes then I will switch all my Cavius smoke alarms, which I can only monitor over 868Mhz and it is one way communication. What is worse is that the alarms only transmit when there is an event, like an alarm or a low battery warning, which can be years apart, so in the mean time I am sort of worried if they work at all.

I have one of these as well and it works well. Zooz makes a hardwire version that connects to your existing smoke/CO detectors Zooz Z-Wave Plus Smoke and CO Detector Bridge ZEN55 800LR - The Smartest House

Have you looked at the First Alert products? We don’t have smart smoke detectors at home, but I would strongly prefer a big brand name detector.

Apparently First Alert (smoke detectors) and Honeywell Home (thermostats) recently merged into Resideo, which is targeting smart residential devices. So it should be better than just throwing a Zigbee chip on a product as an afterthought.

With exactly smoke/CO2 detectors that is what I would prefer.
This way the alarm circuity should work independently and the smart functions are just an interface.
