Is there a Smoke Detector/CO2 Detector that works with ST and can also be hardwired for backup power? I’d like to replace my existing smoke detectors but I want to use the existing hardwiring of my home as well.
Nest Protects come in a hardwired configuration and they will work with Nest Manager 2.5 though not officially supported by ST. I have 9, work great.
I know this is not exactly what you are asking for but wanted to share as a potential option:
The Nest Protect uses proprietary wireless interconnect (not the third wire). I’m not aware of any other hardwired alarms that can be connected without additional hardware. There are a couple potentially in the works from Birdi and Halo Smart Labs. They are both 1+ years behind their original anticipated availability dates, so I wouldn’t wait if your need is urgent. You can also use devices like Leeo to communicate through IFTTT.
He was asking about backup power not the interconnect which is why I included the nest protect.
It really pisses me off that my $99 smoke detectors won’t use the interconnect wire to play well with other detectors.
In some locations the Protects would never pass inspection because they don’t have a hard wire way to communicate.
The odd part is that the pin is there so I wonder if the cable had the third wire if it would work?!
Shouldn’t be too hard to try.
The Fibaro Smoke Sensors (only smoke, sorry not CO2) appear to support hardwire connect, anyone tried these?
They look very cool
This would be bad-ass if they had “capability.speechSynthesis”.
just think… “The front door has opened.”
def contactHandler(evt) {
smokes?.speak(evt.eventDescription)
}
I gather you can detect a contact closure using the Schlage Contact Sensor, instead of triggering it using the magnet. This is not obvious from the Schlage manual. Where can I find out how to do that?
What I’m really after is a wired (interconnected), powered smoke detector to replace my First Alert 7010B, but that can connect to SmartThings.
I understand your post is more than 2 years old; I’m hoping you’re still there.
Correct… here is a picture of how to wire it:
I am not aware of a device that is a wired smoke alarm and can connect to SmartThings at the same time. You will need to get the relay (see post I linked) and a z-wave contact sensor with external contacts. Ecolink now makes a z-wave plus version and I just replaced my schlage sensor with it:

Thanks for your quick reply. That gives me the answer I needed. Obviously I could choose the Normally Open or Normally Closed contact to alarm on either Door Open or Door Closed.
I had thought about using the FortrezZ MIMOlite interface module to respond to a relay closure, but using the Schlage Door Alarm seems to be a cheaper, and simple, alternative, even though it isn’t advertised for that purpose.
There seems to be a missing product here - how about an inexpensive Z-Wave device that would accept 8 binary inputs? You could use that for all sorts of stuff.
Sorry… I may have no idea what I am talking about… but an Arduino device may be what you are looking for. (I have never used one or know any details…)
I wired a kidde relay add-on to my kidde detectors that were already wired together in the house. I ran the signal lines from the relay to my alarm control panel…which is the actually the Konnected.io solution. (Esp8266/NodeMCU) The kidde relay ran about $12-$15 and the ESP8266/nodeMCU ran $10. ST now notifies me if any of the detectors go off. It doesn’t tell me which one.
