YoLink, a US corporation based in Lake Foreset, California, is a line of smart products for residential and commercial use, utilizing wireless technology initially utilized for industrial and other large-scale applications. This technology, LoRa, short for Long-Range, by Semtech, is unique to the smart home market, and provides benefits that include over a 1/4 mile range, superior obstruction penetration (including metal!) as well as extended battery life (up to 10 years!). YoLink benefits include a more secure home or business network, due to a centralized and encrypted internet connection, since the devices are not connected to the internet and they do not rely on WiFi. All communication is encrypted and controlled by Amazon Web Services, for finance-grade security, backups and redundancies. Our patented “Control-D2D” device-to-device pairing allows for establishing device behaviors in advance, ensuring functionality even with the loss of WiFi, internet and AC power*, making it perfect for your critical (must-work) operations, including but not limited to water leak detection & automatic shut-off and intrusion detection and general security systems. *battery powered or backed-up devices
Many Uses! Burglar alarm, panic alarm, intrusion siren, trespassing and theft deterrent – activate the siren manually from the app and/or by motion detection or other automations (using the convenient free YoLink app)
Wireless & Flexible! Self-powered and wireless controller, just install the siren and controller wherever it is needed. No additional wires needed! Or, install the Controller connected to existing wiring, with the siren installed outside. (Both are outdoor-rated, but installing the Controller in plastic junction box or enclosure to protect wiring from elements, etc, is recommended)
Team Me Up! The siren & controller is best when teamed up with other YoLink products such as our Outdoor Motion Sensor, as well as Plugs and In-Wall Switches for flood lights and other exterior lighting control: activate the siren upon detection of activity on your property after-hours, and turn on flood lights to deter criminals and alert others
Longest Range, By Far! Only YoLink, powered by LoRa is capable of up to 1/4 mile range in open air, allowing you to locate the siren virtually anywhere on your property, with no concerns about WiFi signal or dependability
Seamlessly Works with SirenFob: SirenFob is specifically built to work seamlessly with the siren, allowing you to easily start the alarm, stop the alarm, mute the siren (disarm), or unmute the siren (arm) with the press of a button, providing reliable and efficient control for your security system.
A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business!

Great alarm system, siren okay for indoors only though
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.

Yo-link – Features, Range, Extender, Limitations
PROFeaturesDiversity of product lineIntegration capabilities as a smart home deviceLow costBattery LifeCON1/4 Mile range advertised likely clear line of siteIn wooded area reliable range was more like 300 feetAntennas, range extenders not availableUnsupported range extender works but limits featuresSome limitationsFor 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.

Easy setup, okay app, support is polite
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.

From 1 to 10 the sound is loud about 7. Enough to alert neighbours and may be worry an intruder. Needs to hide it, because it is battery operated, if the intruder spot it, will be easy to switch it off. Require a hub, expensive as well. It does the job.
