YoLink Outdoor Security Siren & Smart Alarm Controller Kit - Loud 110 dB, Wireless, Battery-Powered, 1/4 Mile Range, Android-iOS App, Alexa, Google, IFTTT, Home Assistant, Hub Required!

I have many Yolink products and this was one of the essential reasons I got into Yolink in the first place - building an alarm system with no subscription fees that was 100 percent under my own control and which doesn't require Internet connectivity or cloud dependence. Like my other Yolink products, (water shut-off valve, leak detectors, temp sensors, outlets, etc) this is well-made and solid and not some cheap piece of plastic. A hub is required to get any of it functional, but they practically give those away with their equipment bundles so it's no big deal. I have this siren indoors and it's loud enough for that purpose, but it's inaudible from outside and I don't think would be very useful if even mounted outdoors. But inside it works fine, for outside I put two (non-Yolink) outdoor sirens that are VERY loud when activated by two Yolink power outlets, which are set to power on when the system is armed and tripped. I originally purchased two Yolink "alarm fobs" which - to my complete bafflement still to this day - are not capable of arming/disarming the alarm system. For that I needed a "Flex Fob", which I purchased instead and returned the first ones. The Flex Fobs do the arm/disarm task, plus they not only have two additional buttons available for other tasks, (I use the others to open/close my garage door), but they also have short & long-press configurations for each button, so there's actually 8 actions available for each fob. (4 buttons x 2 actions each button.) All of it can function independent of any wi-fi network or Internet connection, although obviously Internet would be needed to send out notifications. The Yolink app can be somewhat confusing, especially when it comes to configuring an alarm system. I needed to consult quite a few of their support documents to get this dialed in correctly, but once you understand the mechanics of the Yolink app and how it wants to do what it does, it gets easier to work with. It's far too complicated a process to go into here, but basically it amounts to enabling or disabling an alert policy, therefore "arming" or "disarming" the alarm system. (Disabling makes alerts do nothing, enabling makes it trigger other devices and send out notifications or whatever you configure it to do.) Yolink support documentation is there for help, and their tech support is also very good - twice I had to contact them regarding linking devices and why the original "alarm fob" wasn't arming my alarm. Both times they responded quickly in English and got me through my problems. I don't use any motion detectors so I can't attest to them, but I assume they work as well as the rest of my Yolink devices. Their contact sensors, temp sensors, and leak sensors have all worked flawlessly, hub configuration was painless, integration with Alexa was equally painless, and although it took some puzzling on how to configure everything in the alarm system, in the end it's been money very well spent.

PRO Features Diversity of product line Integration capabilities as a smart home device Low cost Battery Life CON 1/4 Mile range advertised likely clear line of site In wooded area reliable range was more like 300 feet Antennas, range extenders not available Unsupported range extender works but limits features Some limitations For house monitoring of crawl space temp/humidity, water leak detection, motion in attic etc., the product line works extremely well and has excellent smart home integration. The goal was to simplify install, minimize/eliminate wiring for sensors, and to gain smart device capabilities. When working for external device monitoring such as driveway gates, package delivery box notification at a range of 450 feet through wooded areas challenges were uncovered. For the package delivery box, the original concept was to mount a garage door sensor flush (horizontal) on the bottom of the lid that would toggle when the lid was opened. From what I could glean the device is designed to be installed on the inside of a garage door (vertical) with door closed. There was not a software option on this sensor to alert on normally open vs normally closed. Therefore a bracket needed to be assembled to mount the sensor in a vertical position for the device to operate. Would be nice if the device offered this option. During the process the range was learned to be a challenge. Moved hub outside, tried different orientations to try to optimize internal antenna (vertical / horizontal) different sides facing device and was not able to mitigate signal limitation. Yo-link does not offer an antenna, and/or range extender. Found a helpful "non-supported" solution to create a signal relay solution. This uses a yo-link Security Siren & Alarm controller and yo-link Outdoor contact sensor. Between these two devices a relay is required. I found and electronic relay with NO normally open and NC normally closed output contacts; "OONO DPST 1NO 1NC 8Amp Power Relay Module, AC/DC 12V Control Voltage" which worked perfectly. Configure the remote device to trigger the Alarm controller. Replace with siren with the input to the relay module. Attach the contact sensor to either the NO/NC contacts as appropriate for your project. This solved the range issue in this case. However, the ability to monitor if the device remains open and is not closed is lost. A goal was to add this solution to the driveway gate and obtain a notification if the gate was not closed. At this time I do not know a solution to the range challenge combined with some of the additional features yo-link offers. I am using these devices outside of their intended design, so I will still rate them highly. However, it would be nice for yo-link to have an extended range solution that supports all of the device capability as well as a tilt sensor (garage door sensor), that allowed the NO/NC configuration to be modified. Overall I have been impressed.

This is a nifty, simple and cost effective alarm. It’s decently loud, small/low profile and easy to setup. I don’t like that there is no LAN only support- your app and hub both have to travel all the way to the cloud to activate or deactivate the alarm (support says it’s in USA, not China, but I haven’t verified this yet). This causes lag and the app sometimes claims the siren command failed but a few seconds later the siren does activate/deactivate. I contacted their support team about this and they admit it’s a problem but they had no real solution other than exchanging for a new hub. Not great. This hub/siren does integrate with home assistant, despite what someone else said in the comments. I have it activated with a zigbee push button through an open source hass integration. To create a hass automation, install the integration and then tie it to a service call, selecting the installed service.

As an early adopter of yo-link hub and sensors I have been requesting an alarm with outside siren for a couple years now. I purchased their first siren alarm hoping to be able to get it to activate my large "wake the dead within a mile radius" old school outdoor siren that came with my original, monitored alarm system. I had it hooked up to a 110/12v converter plugged into a yo-link smart plug but could not figure out how to program a sequence to activate it when the white siren was activated. I purchased this new unit when it came out and just got around to installing it. I usually pretty good at figuring out setups ,but this one had too many options. Once I had it connected to my hub and visible in the app it the drop down menu options for the siren had a "call tech support" option. This is why I rated this a 5 stars. [Fortunately I was connected to someone other than "Eric" who made promises to me that were not kept, a real BS artist] The tech that helped me was able to see my system, get in and with a few actions on my part set this up to my specs for simple, easy control. Very nice. The "almost" perfect rating comes from the fact this unit can still not be setup to activate my old school siren, but the tech told me enough customers where, like me, wanting to utilize an existing siren that yo-link is about to release an alarm sensor that can. So if you have an existing system you're looking to modernize I'd wait until the new one come out. Otherwise this is loud and simple and a great companion to all the other super yo-link sensors. I have sensors, plugs and deadbolts in my yo-link system and of all smart home products they are by far the easiest to setup, scan the QR code and it is in app/system. As a result when looking for smart home products Yo-Link is the first place I look. Hey Yo-Link how about a temperature controller that I can program to turn my hot tub heater on and off. I've seen the thermostat with probe but it doesn't look like it can control anything.

With the YoLink Alarm Kit yes, simple physical installation but this system does not function good or properly. I gave YoLink a chance and ordered KERUI Alarm Kit. This system was as easy to install and functions as an Alarm System should with no catches. If I had an option to contact the seller of YoLink. I would have allowed YoLink to make a deal but now. I will ship both the 2 YoLink Alarm kits back and only purchase KERUI! Thank you KERUI!

It does exactly what you want it to do, make a loud audible alarm sound. The battery package comes with it, and the batteries will last a good enough time for prolong use. I would get it again if I needed. Side note, mount this high up in a place that isn’t easy to get to but in a place that is central to the house/location you are wanting good coverage. Mounting it high up makes it harder to stop for an unwanted guest.

Have several YoLink devices including the hub, water sensors, water main remote shutoff, motion sensor, door sensor, and smart plugs. I really like the app, which has no subscription cost. It's super easy to navigate, understand, and allows control / monitoring of all the devices. Also very easy to connect new devices to the app, just takes a couple seconds. All of the products are high quality and work well. A+
