Smart Siren Alarm, Wireless Home Security Alarm with 110 dB Loud Audible Alerts, Remote Control, Compatible with Alexa, Google, Home Assistant, IFTTT - Hub Required

I purchased the Yolink Hub and Water Leak Sensor Kit in 2021. I also purchased the Yolink Smart Siren Alarm and 3 additional sensors. Last night about an hour after going to bed I was awakened by the Yolink Siren Alarm. I grabbed my phone and the Yolink app had sent me a notification of a water leak under my kitchen sink. I got out of bed to investigate and found that hot water was leaking from the pipe under the kitchen sink. Hot water was already starting to overflow from the floor of the under-sink cabinet onto the kitchen floor. I immediately shut off the hot water valve, which stopped the leak. I then got a bunch of towels and quickly soaked up the hot water from inside the cabinet and the floor. I finished drying as best I could with paper towels and then got a large window fan to circulate air in the cabinet to dry it out completely.I can only imagine what would have happened if I had not had the Yolink water sensor under the kitchen sink. I would have slept through the night while hot water spread for hours from my kitchen into the living room, dining room, guest bedroom. Carpets and furniture would have been ruined. Baseboard molding and drywall would have had to be replaced. What a nightmare!The Yolink water sensor saved me what would have been probably several thousand dollars in water damage to my home and belongings. I’ve got their water sensors under every sink, behind every toilet, behind the refrigerator (water line to ice maker), beside the clothes washer and the dish washer, next to the hot water heater, everywhere there is the potential for a water leak. You can imagine how glad I am that I have the Yolink water sensor system protecting my home and possessions.

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!

Easy to connect and works very well! I needed something that would give an audible alarm for in the middle of the night or if I’m unable to let my family know I received an alert. This works perfect and is loud enough to alert anyone at home there is an issue.

YoSmart technical support has been AMAZING to deal with. After reading my review, they've been proactively emailing me and working on a fix, which works for one alarm. Now i want it to work for two. I'm upgrading this to 4 stars and will give them a fifth when the last issue is resolved! Way to go, YoSmart.Like all YoSmart products, this installs flawlessly and works like a champ! Having said that, however, I am finding this difficult to work in my scenario. If there is a way to make this work, I'll upgrade my rating.Here is the scenario:I have a yolink siren, water sensor, and door sensor.I want the water sensor to sound the siren, always, when it detects waterI want the door sensor sound the alarm only when I am out or sleeping. Not when I'm home.Here is the issue. YoSmart automation is very limiting. It does let me enable or disable the siren based on "home/out/sleep/wake", but it disables the entire siren. I don't want to disable the entire siren, just the doors.You'd think this is a pretty simple use case but for some reason I can't make it work. Sure, I can use a schedule but that's not what I want. I want to be able to disable the door alarms when I'm home and I can't seem to make that work. Perhaps I can use an Alexa or IFTTT automation to accomplish this, but I would really like to keep all this functionality in one place....

If, like me, you've purchased YoLink water "Sensor 1" type water leak detectors, you know that they do not have any type of internal audio alert. As a result, if a sensor goes into alarm when you are away from your phone (or away from home), nobody in the house is likely to be aware of the leak, which completely negates their functionality. This siren / alarm will make a loud enough noise so that anyone in the home will be alerted to the potential leak. This product is the missing piece of the YoLink puzzle, which makes for an excellent alerting system once added.

Excellent product and customer service.
