Easy setup, long range, reliable alerts
Bought this sensor to monitor my RV that is parked at the barn about 100 yds from the house. Winterized it, and setup the YoLink temp sensor inside, indoor motion sensor, and outdoor motion sensor. The speakerhub is in the house on wifi and gives alerts from the devices for motion and low or high temp. Have had it setup for a few months now. It's been very reliable, handles the distance well. The alerts are configurable, I use email, and the app notifications. Was super easy to setup, device batteries haven't needed any attention so far.

This sensor has a range which is beyond imagination
Well there have been so many sensors. So why buy yolink? If you are thinking of this question then stop thinking and buy first and the read my review. I have been experimenting with smart home products since last 7 years when they were barely launched starting with smart bulbs and moving on to all different products and using Alexa to bind them and then comes these sensors. Frankly I have wasted tons of money on contact and motion sensors. I have tried sensors linked to hubs via zigbee and zwave which have their own problems with regards to range and going offline etc etc Then comes wifi sensors which require routers in every room and they have a significant lag ofcourse. And if your wifi is down then bye bye to them Frankly I was so fed up I stopped using any sensors. Controlled everything with voice which works atleast 99% of time And then I read about yolink. Their loran technology. I am from aviation and yes we have knowledge of long range technology and different wavelengths as such. So we'll it seemed interesting. But I had wasted enough money and now I cannot trust anyone unless I try my hands on. For a change just ordered 2 motion sensors and one hub just to experiment knowing I will lose my money again I stay in part of world where we use brick and concrete walls where even drill machines give up, forget any sensors. And when nothing works it's YOLINK which works. And they were flawless. I did a stress test. Kept their hub in living room and I installed motion sensors in bathroom which are inside my bedroom. There are like quite a few walls and doors between hub and sensors. And oh my god they just work instant. Like super instant. They are truly truly SUPER LONG RANGE So they can pass through walls concrete bricks doors and what all and still respond instant Best thing each set up literally takes 20 secs flat. I bet not more than 20 secs ever. I was so happy I order so many more sensors. As of now I have 12 window door sensors, 5 motion sensors, key fob and their speaker hub. To set all these sensors over all it took me like less than 5 mins. Such straight forward pairing and app is straightforward. Also do register for their newsletter as I ended up getting 20% coupons which saved quite an amount. Overall I feel nothing can beat these sensors ever in terms of simplicity reliability and range which is my fav as its superrrr looong range. Hats off for such wonderful products and technology.

This is the best system for smart home use with Alexa and smartphone or apps
i have this 1000 feet from my home and they work flawlessly. I have 25 different types of Yo-link devices ( water leaks, motion. temperature, humidity, light switches) I monitor 3 barns for motion inside and 3 for temp/ humid, , greenhouse temps and humidity, 2 sump pumps, 2 ejector pumps, next to washing machine, under all sinks, in mailbox, on long drive entrance, in my pond. Every one has worked flawlessly. It caught an ejector pit overflowing onto basement floor and i got to before damage could occur. If I forget to turn off barn lights (400 feet away) I can just tell Alexa to shut them off- other brands do this but not a 1/4 mile away from home! I know exact moment mail is delivered. The temperature of my 1 acre pond. I'm alerted to trespassers and if some gets into my pole barns! It all displays on my echo show, smartphone, apple watch, and all of my alexe's tell of leaks in house, motion or temp when asked. Easy breezy setup. Low priced!

Absolutely LOVE YoLink products, what a great company!!
We have so many YoLink products, but since this review is specifically about this indoor motion sensor, I'll try to stick to that. First, this is much smaller than it appears in the pictures which was a great surprise for me. We're using this to monitor the evening activities of a senior dog so it is mounted on the side of a table in our living room, which means the small size was welcomed. Like all YoLink products, it was a snap to install, just a few taps in the app, and it was ready to go. And it works as expected. Every time it senses motion it sends an alert (depending on config) and it reliably senses motion. Almost too much sensitivity for our needs, so we had to turn the sensitivity down to "low" so that it was only catching when our dog actually got up and moved, not just when she twitched or raised her head or kicked her legs in a dream. The only reason I gave 4 starts instead of 5 was for a few options that I think are missing in the setup and configuration for this motion detector. First, I would really love a way to turn it off during certain times. You can turn off alerts by using alert schedules, but you can never turn it "off" unless you physically turn it off which we of course don't want to do. It would be really nice if the app allowed you to configure an "active time", a time during which you wanted to track motion, and an "inactive time", a time during which you didn't want or need motion tracked. Since you don't have to be alerted, I know it seems like a small issue, but I don't see any point in wearing down the batteries to have it sense motion during times that I don't care. The second issue is that I would really like to be able to schedule different alert schedules for different users. This is an issue with many of their products, not just this one. When you configure a device for an alert schedule in the app, it uses that alert schedule for EVERYONE that uses the app, which doesn't make a lot of sense to me. We have a lot of their products and my husband and I definitely have different wants and needs for being alerted by the devices, and there doesn't seem to be a good way to configure different behaviors for different app users. Most devices have behaviors that apply to the device, not the user. THANKFULLY because these products integrate with Amazon Alexa (very easily, I might add, by simply activating the YoLink skill), I'm able to do what I want to do using that software instead. But it would be nice to do it directly through the YoLink app. YoLink support has been very responsive to my questions and assures me that what I want doesn't currently exist in the product or app, but they do mention they will pass it along as a feature request. I don't know if they'll actually implement it anytime soon, or ever, but at least they responded!

This is a great sensor to bundle with other YoLink products. Also, can work with routines on Alexa. The signal is strong, even a considerable distance from my house, and I’m still on the original batteries almost 1 year in. I use this motion sensor to turn on outside lights in the night near the edges of my property. So far so good. It is mounted on a tree.

I have been using YoLink products for 4 years now. This is another great product of theirs. Simple to install, great battery life and does a great job of what it’s supposed to do. Best thing is the long range. No more worrying about whether your Wi-Fi signal is going to be strong enough, YoLink products use LORA, which is a low frequency, long range radio wave system that gives up to 1/4 mile range. I have YoLink sensors as far as 800’ from my hub and no problem. With the 40 or so YoLink sensors I have, I’ve had to deal with YoLink tech support a few times and have always found them to be over-the-top excellent in their response, even going so far as to send me replacements as long as several years after my purchase. I’m an electrical engineer with a specialty in digital communication and I design radio frequency communication products among other things. I have nothing but good things to say about YoLink products and support.

Love the Yolink brand. This sensor works great. I have it set up in the basement and it will let me know each time my cat goes to his liter box. The vet wanted to know how often he was going to the box as he has a UTI. The logs were helpful keeping track of the data. I also have it turn a smart outlet on that has a floor lamp plugged into. The lamp only turns on when it is dark but the sensor reports 24/7. The sensor also turns the light off after 10 minutes of no activity. Getting another for my garage.

Works great with my Yolink hub monitoring temperatures all over the house. Very unobtrusive and sensitive. I would not trust this in an uncovered place to be honest but that's just me. I mounted mine over the door where it is well sheltered from the elements by the overhang. Very useful when I am in the shop and can't hear the driveway alert. Phone beeps and I glance at the camera feed and I know there is a package or whatever. Exactly what I wanted as I hate the Ring system.
