Yolink is a great system! You're gonna feel so much safer!
We bought this to go with our new Yolink leak detectors so we could have a central location for an alarm. Once we hear it , I check my app and it tells me where the leak is detected. The notifications are easy to understand and I've had no issues with the range of each sensor with the alarm. We also bought the Yolink door alarms and the Key FOB (which is mainly for my husband who doesn't want the app or the notifications). Both are compatible with this alarm also. The app is really easy to setup and use. We had a different kind of door sensors before Yolink and I'm really glad we swapped to Yolink. I feel safer with this Yolink alarm.

Reliable and easy to set up
The alarm is easy to set up. It has three volume settings: loud, loudest, and hearing damage!! To silence the alarm there's a big button on the front or you can use the app from your phone. This alarm is especially useful for anyone in your home- for us it's an essential addition because we don't always have our phones nearby.

I like the fact this has a switch on the side to change volume!
I’m totally blind! The first thing I noticed about this when I took it out of the box. I noticed a switch on the left side of it and that it had a screw hole on the back to mount it on a wall. I next felt around on the back and found the battery cover. I wondered what the slide switch was for being it has 4 point altogether. So I put 2 AA batteries in it and nothing happened. So I slide the switch up one spot and the siren sounded. I slid it up another spot and the siren got louder! And the top spot is the loudest setting. I really like that. Makes it easy for a totally blind person to be able to set the volume without having to guess how to set the volume. I also noticed that the Micro USB port is on the left side as well. My own thinking is I think that the port really should have been on the bottom. That away when it is put on a wall, the cable comes out the bottom and not the left side. On the front of the unit is a button in the middle. This button looks to manually start or stop the siren. Took the batteries back out of it and then scanned the QR code on the siren and plugged it into USB power and the unit came online to the hub. Then I put the batteries back in and plugged it back into USB power. The rest of the stuff as far as I can tell, needs to be done from within the App. Looks like you can set the siren to sound anyware from 10 seconds to never shut off. You can also control the siren with Alexa if you have your YoLink account connected up to Alexa. Alexa turn on Siren. Alexa turn off siren. You can also use it in Alexa Routines as well. The YoLink App. As far as automation needs improvement for a totally blind person to use that function of the App. There are unlabeled button in the screen that make it so a totally blind person trying to setup automation for the siren to have to do it by trial and error. But I did get it done. I currently have it setup to turn on the siren when the motion detector that is in the mailbox triggers. It is responcive when motion is detected. It triggers about 3 seconds before the Alexa routine announces that the mailbox door is open!

Good product, bad tech support!
The product is of very good quality, and seems to be very reliable. Would have given 5 stars but the support is not good. If you have to contact tech support you're probably gonna encounter problems getting answers. I had issues like getting partial answers, to nobody ever responding to my questions, to a rep stopping me messaging me halfway through the setup process. It was very, very aggravating

Extremely pleased
After several incidents of main drain clogging and having to deal with the after effects of debris backing up into my basement, and worst of all, not knowing about it, I stumbled upon the YoLink products. I installed water leak sensors in key areas of the basement (the laundry room, next to a boiler, water heater and basement bathroom). The sensors are equipped with several contact points and as soon as a drop of liquid touches them, sends an instantaneous notification to my e-mail, and most importantly, my phone, so no matter where I am, I’m aware of an issue that needs my attention. The app is incredibly well thought out and intuitive. It took minutes to set up and get the entire system running flawlessly. The signal strength of the sensors from all the way in the full basement is incredibly strong. I also bought two door sensors I wanted to monitor, and a very load siren connected to the system. All work flawlessly with instantaneous notifications. I did have a question regarding the app, and tech support responded to my e-mail within an hour on Saturday night. If I could give YoLink 10 stars, I would. Buy their products, you’ll be very happy you did.

Yolink Smart Siren
The siren connects and performs very well. Sound quality is low to mid quality. Why the 3-star review? Well, it looks like a prototype rather than a finished product. It uses Micro USB Micro. This is 2025, NOTHING should come with Micro USB. Why does this matter you ask? It is hard to find good cables that are shorter or right angled in white. For USB-C (today's standard), these cables are easy to find. Many devices today have neat mounts that hide the cables. Look up mounts for Nest Mini, EERO, Echo Dot, Blink Sync Module etc. They all have mounts that either completely hide the cables or greatly diminish the cable profile. There are a couple mounts that I think would ALMOST work for this. However, the cables that come with them are...you guessed it, USB-C. This device has a huge USB wall adapter that the USB cable plugs into in a way that has a big profile (not flat or 90 degree) and a long cable. It is an absolute eye sore. Yolink should develop and sell or ask a third party to develop and sell a clean wall mount for this. Overall, performance is fine. Aesthetics and finish are not quite there.

In my opinion siren is very loud, afterall it's indoor use. So depends where you installed you may want to lower the volume. Connection wise no issues. Great product.

Pour le prix, il est bien. Un système d'alarme a bon prix, par contre le système n'est pas très intuitif et pas facile a configurer. Avec un peu d'effort on y arrive finalement. J'ai aussi un petit soucis avec le fait les motions sensor ne puisse pas appartenir a plusieurs strategies de sécurité. A moins que ce soit moi qui n'arrive pas a bien le configurer. Je recommande vivement si vous voulez installer une system de sécurité a moindre coût, les senseurs fonctionnent bien et le système est très réactif.

Terrible, you need to buy their HUB to use it. They don't tell you that on the ad. You only realize it once you are trying to set it up. I'm not buying anything else from them. It would save customers some grief if they specified it on the Amazon ad. Returned it the same day.
