EDIT: after 2 months some of the weaknesses become more clear. Whenever the product is disconnected from the WiFi, the nightlight defaults to full brightness forcing you to reconnect to set it back to auto-brightness.
I just spent 2 hours replacing all 12 of my smoke detectors with Onelink Safe and Sounds to get Alexa in every room. I can tell you, I definitely found some improvements to how I would've started installing from the 1st one. So here I am sharing what I learned. It shouldn't take you more than 2 minutes to install each one.
1. Don't rewire. Each detector comes with 3 different adaptors presumably for different brands of smoke detectors. I rewired my 1st one before just using the provided adaptors.
2. Don't take the screws for your old mounting bracket in the electrical box completely out. Simply unscrew a little bit, take your old mounting bracket out, and replace with the Onelink's mount. Make sure the side of the mount with the picture of the screw is facing down or your alarm won't turn on or stop chirping.
3. Make sure you set up all the devices one at a time ON YOUR PHONE as SOON AS YOU INSTALL THEM. Don't be a knucklehead like me and install an entire floor before trying to sych. I had to wait until they stopped flashing then moving the ladder around to press the button 3 times to reset each. Otherwise my phone would detect the hallway when I wanted to set up the bedroom.
Out of 12 I got 1 dud which wouldn't stop chirping no matter what after wiring. But when I used another Onelink where that one was supposed to go in the closet, that one worked. So I'm in the process of getting that one replaced from amazon.
I mainly bought the OneLink for its Alexa integration. I have basically replaced all my lights in the house with Phillips Hue and having voice control is invaluable to me. In this aspect, the OneLink and Alexa do a great job together to allow me to turn off all the lights. I am also in the process of setting up an IFTTT alert which will turn on all the lights in my house when smoke alarms are triggered. I'm ok with the rest of the features.
The only disappointing feature is the nightlight. The Nest has a motion sensor that turns on the nightlight when you pass under it. The OneLink has an autodim setting which dims the nightlight when it gets dark but I would prefer to have the motion sensor.
Speaker quality is okay. It's a bit quiet and you get an equalizer with a balanced setting and a default setting. Default setting sounds better but balanced setting is louder but flatter. Don't expect bumping bass at all especially at low hz. It's passable but if you crank it up, warping starts. You can definitely listen to Top 40 with no issues in your room.
The alarm itself is just a normal smoke alarm screeching however this is in-line with other products including the Nest. It would be nice to be able to switch to different alarms. Room announcements are limited as well by what's pre-programmed. It would be nice for me to be able to use text to speech for room names instead of them being pre-programmed "master bedroom" "kids bedroom" "guest bedroom." I thought Alexa could do text to speech?
The OneLink app is also a little difficult to use. Other than my slight mishap of trying to sync all the alarms on one floor, sometimes I would accidentally miss the very easy to miss "alexa integration" button on the bottom of the GET STARTED. I would then have to reset the smoke detector again to get the prompt back up. That was annoying.
Overall I think it's a good product with excellent Alexa integration which is why I bought it. However, the nightlight, speaker, and
