What's required to use this battery-powered Onelink Smoke & Carbon Monoxide Detector?
You'll need to download the Onelink Home App to your phone or tablet, and for the non-alarm features, you'll need home Wi-Fi with 2.4Ghz and an 802.1 lb/g/n router
Once the Onelink unit is installed in my ceiling, what are the next steps?
Once the alarm is installed, the unit will walk you through setup with the Onelink Home App. If you have more than one unit, set each one up though the app as you install it before moving on to the next one.
How many Onelink Smoke and Carbon Monoxide Alarms can be interconnected?
The NFPA (Natiional Fire Protection Association) states that up to 18 total units can be interconnected, with a maximum of 12 of those being smoke alarms.

"The First Alert Onelink 2-in-1 smart smoke and carbon monoxide alarm alerts you to both types of danger in your home. Emergency notifications alert you to danger via your phone, while voice and location technology tell you the type and area of danger; the alarm also uses a traditional 85-decibel siren. Wirelessly interconnect with other existing traditional hardwired alarms and other Onelink devices (sold separately) to create a smart home safety network, so if one alarm sounds, they all sound. This alarm is also compatible with Amazon Alexa; you can ask Alexa to check the status of your Onelink alarm. The Onelink Home App is compatible with both Android and iOS devices. The easy-access door makes battery changes simpler. If battery power is getting low, Onelink will let you know via a notification in the app before the alarm starts to chirp."

There was a problem filtering reviews right now. Please try again later.
I experienced many of the Onelink app setup issues that others on here have reported. With a little patience and two or three attempts I was able to get the smoke detector setup in the Onelink app and showing up as a HomeKit device in the Home app. I then hit the test button in the Onelink app and the smoke detector sounded. The interconnected smoke detectors also sounded a moment later. The test event was logged in the Onelink app. Everything was good...or so it seemed.
Pressing the test button on an interconnected smoke detector also sounded this one. I will note that this event was not logged in the Onelink app nor did I receive a notification for it. I saw that another reviewer mentioned this before I purchased it so I wasn’t too surprised when this didn’t work for me either.
For a true test I purchased canned smoke for testing smoke detectors on Amazon. I followed the instructions and discharged the canned smoke under the smoke detector. As expected the smoke detector sounded and the remote interconnected smoke detectors also sounded. Unfortunately I never received the push notification for the smoke event from the Onelink app. I saw some reviewers mention that it took a couple minutes to receive so I waited. Eventually the smoke dissipated, the alarm cleared and the smoke detector automatically silenced. Eventually I opened the Onelink app and refreshed the smoke detector. In the recent history the last event showing was the test event from when I installed it. There was no record of the smoke detected event (and still is not days later). Furthermore, Apple Homekit was also never notified which would have trigged my automations and also sent a separate alert to via phone from the Home app. In the end none of the smart features on this smoke detector worked during my simulated smoke test.
I ended up contacting support about the push notifications I was told that this is a known issue and the developers were working on a fix. I never received that fix but was contacted to help them troubleshoot a couple days later. After a asking a few questions about my related issues via email I was told that HomeKit alerts are not currently supported. In other words if the alarm was activated it would not notify Apple HomeKit and therefore my automations would never be triggered. This would also prevent me from receiving notifications from the Home app (which should not rely on Onelink’s infrastructure).
In the end I am returning this smoke detector since it does not function as advertised. After learning that this device does not have full HomeKit capabilities I did not continue to troubleshooting with Onelink. They did appear to be interested in troubleshooting and fixing their push notifications but the lack of full HomeKit support is a deal breaker for me.
Words of advice:
- Make sure you keep your mobile device close during the setup process. This isn’t a guarantee that it will work the first time, but most HomeKit devices are designed to have the iOS device close. This does become painful, as it’s on the ceiling.
- You will probably need to reset the alarm a few times to get it to pair. Be patient, and it will join both HomeKit and your WiFi... eventually. So, keep your ladder nearby.
- Set up the device through the Onelink app. Yes, this app is terrible. I attempted, during my second try, to use Apple’s Home app first and go back to the Onelink app to finish. Nope. Failed again.
- Again, patience.
- If you get the “Setup Completed with Issues” message (you will) go back to the main screen. More than likely, the alarm won’t be there. Refresh the screen a few times, and if that doesn’t work, force close the app and open it again. It should appear with an error message to “pair” the device. Click on it while your phone is near the alarm and scan the HomeKit code (yes... again). It should pair this time around.
- If it doesn’t pair after scanning the HomeKit code... reset the alarm by pushing the bottom 5 times and start again.
Per the usual, Onelink can’t seem to make the setup as intuitive as most other products for HomeKit. Now that it’s paired, I’ll give it a few weeks to see if it’s going to do anything sketchy like drop the WiFi network. I’m giving it two stars solely for the painful setup. I’ll adjust my review if everything remains stable.
After installing this device, I ran tests on it. They worked as a normal smoke detector would, but my phone didn’t receive an alert. Moreover, it doesn’t even show up in my history! I had the unfortunate experience of dealing with their support department after this.
Aside from having to bounce you around until they find someone who actual has some technical experience, they still had to “elevate” the matter. I made four phone calls and spent nearly three hours total on the phone just for it to be thrown over the fence to someone else. I’m supposed to be called back within 24 hours. I called them yesterday. Given that it’s Christmas today, that call isn’t happening.
If this were not bad enough, the installation issues described in the other reviews happened with me as well. The app is needed to install and it was glitchy, skipping needed dart steps before timing out. This is probably because the device is developed to only allow changes when in Bluetooth range and the device has to be wired into the ceiling before the app recognizes it (I tried to use the app before turning the breaker back on and the device wasn’t found). Given the two restrictions, it’s easy to fall outside of Bluetooth range unless you’re on a ladder holding the two in close proximity.
I have no intention of keeping a $100 product that is LESS smart than a $20 product at Home Depot. I’ll update this post if I ever manage to get my phone call and they’re able to resolve this to reasonable expectations...
I was contacted by customer support via email Christmas evening informing me that I would be called the next day. A manager called me in the morning and scheduled a precise time that a technician would call. The technician called me on time and had me reboot my router, my phone and disconnect the device from power. Then I unpaired the device and went through the procedures to pair it again (still took me three attempts). After doing all of this, I started to receive history and push notifications.
The history reflected a test that I conducted as well as a simulated event with smoke. I disconnected my phone from WiFi and Bluetooth again to do this. After the device sounded the alert, I received a push notification within a minute of it going off.
The software seems glitchy to me, but I’m satisfied that it works well enough at the moment to meet my needs. The technician filed a report on my experiences and hopefully they work the bugs out.
Today is January 2d. After the debacle with the first product was resolved to acceptable terms, I attempted to install a wireless version on a separate level of my house. After multiple attempts to get through the installation steps, I survived the process to successfully sync it to my HomeKit app.
Yesterday, I started a fire (in my fireplace), but in a moment of absent mindedness I did not immediately open the flue. Within minutes, the wireless smoke detector went off. After opening the flue, I immediately looked to my phone to silence it, except my phone never received the alert, so I couldn’t. Even more of an issue was that the device refused to be silenced even after manual attempts. And finally - as an ultimate fail, it never set off the wired device. Given both of these were set up using the Onelink app and both were shown in my HomeKit app, the wired device should have definitely been triggered. This afternoon, I looked through the history of both devices, but as expected, yesterday’s alert was not reflected in the history archives of either device.
I called customer support to let them know in hopes that the repeated failures would produce an improved response to make amends but, sadly, I was prompted to create another ticket. Onelink customer support operates as if they are the only option in this field. I have returned both devices and have asked for my refund. I will be looking to Nest or a similar provider to sell me a product that works!
