## Description

desertcart.com: YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range for Fridge, Green House, Pet Cage, App Alerts, Emails, Text/SMS alerts- Hub Required : Patio, Lawn & Garden

Review: Cheap peace of mind! - I wish I would have installed this immediately after I received it! It would have saved me hundreds of dollars and hours upon hours of prepared meals that were lost. Live and learn. This little device is well worth it! Very easy set up and it is sensible to minor temperature changes. I get multiple alerts when the temperature or humidity has changed. I was literally ready to sell my freezer that was only a couple of years old. I live in Costa Rica and there are unpredictable power outages and/ or surges that have caused the freezer to go out. No more. Recommend without hesitation.
Review: Highly recommend - We have tested various devices for a few weeks. I have to say that we are very pleased. The first thing we noticed when unpackaging was that everything seem to be designed and made with attention to detail and care. That was a little surprising for us. Many times you get cheap packaging and apps that look like they were created in a single afternoon. Not so in this case. We had to double check to verify that this is a start up company. By all outward indications, it feels like it’s a well polished company that has been in business for quite some time. All manuals and set up information is available online. Do not expect much in the box. We had a little difficulty finding the information we needed at first but we were grateful, and still are, for the fast response from the company. Since we mentioned the company, we have to note that any kind of support request is answered promptly, even at odd hours of the night. That was surprising. But they have always been friendly and helpful, even when we should have checked product documentation first. The initial set up was a little challenging with Wi-Fi. But that is not due to product limitations. It is due to limitations on the wireless routers we used. The wireless routers we used did not allow us to separate the 2.4 GHz and 5 GHz networks. This system uses the 2.4 GHz network, which is needed in order to have the range. In the end, which simply hooked up the network hub to the router using the provided ethernet cable. Everything has been pretty much smooth sailing. Again. The system requires a 2.4 GHz Wi-Fi network. If you have trouble getting it to connect wirelessly, the issue is almost certainly your wireless router failing to separate the two networks or failing to allow the device onto the 2.4 GHz only. It’s not a product limitation or defect. Our recommendation is just to hook it up with the ethernet cable since the range is very long, anyway. Before using the system, we recommend updating the firmware on all devices manually. Depending upon how long it has been sitting in the desertcart warehouse, you may have an older version of firmware and might experience a few bugs. That was our case. We had a few problems with erroneous notifications that were rectified as soon as the firmware updated. The update, you find the firmware version in the device and tap it. The firmware does update automatically. But if it’s your first time setting up, it’s good to manually update the devices. We would love to see a way in the app to review the firmware status of all devices on one screen and manually trigger a firmware update for all devices from that same screen with a single click. But this is merely a want, not a flaw. Do not forget to edit the alarm strategy before you start using the system. It appears to default in the app to multiple strategies, which can mean getting an app notification, an email notification, and or text message notification each time something is opened or motion is detected. That might be something to look into on the app development side as far as prompting you during set up to choose your desired preferences. We have had no difficulties with the devices maintaining contact with the network hub. The network hub has reported itself going offline once or twice overnight, but this appears to be momentary and related to a firmware update automatically applying and automatically rebooting the device. Battery life so far appears to be really good. We are surprised by the quality of the 3M self adhesive tape on each one. There is no alcohol wipes provided, but we used simple rubbing alcohol and a cloth to clean the surfaces prior to sticking the devices on. You can do similar or just make sure that it’s really clean. As a test, we applied some of the devices to a surface that was not prepared/cleaned ahead of time. those devices have no problem sticking to the surface and have not fallen down. They appear to be well secured when we try to tug on them. We would love to see the adhesive strips offered as a replacement item for purchase. We can see down the road people moving devices around, say if they’ve changed their minds about location or if they move. We had also thought about having an extra mount for the motion sensor so we could move the motion sensor between different locations at different times. This was because we were only able to buy a limited quantity due to inventory at that time. But that is something that others might be interested in purchasing at a later date. The motion sensors have been updated to include sensitivity adjustment. They can be pretty sensitive, detecting slight movement even in the dark. We have no complaints. The range and spread appear to be great. The door/window sensor performs equally well. it can be mounted in virtually any orientation and still function so long as the sensor portion of each piece is within about 1/2 of an inch to the other. so you could even mount one of them at a 90° angle to the other. So long as they are within that distance to each other, they still function perfectly. We found this to be necessary with one door where we had a proper clearance on the door but did not have proper clearance on the frame. The products integrate seamlessly with IFTTT. We would love if the temperature/humidity sensor had the option to show more frequently than one hour on the history graph in the app. But the graph is clean, uncluttered and easy to read. We will soon be testing additional products. We are adding additional door sensors and motion sensors to the system, which will then have approximately 20 devices connected. We are also going to be testing for the first time the garage door motion sensor (ordered). We were originally going to test the motion sensor/ garage door opener combo, but none of the garage door openers we have available appear to be compatible. Afterwards, we will test additional devices on our “wish list.“ We have found zero indication of user data tracking, analytics tracking, or communication with ad servers on the app. It really does appear to be simply designed to do what it is supposed to do and nothing more. It’s refreshing. So to summarize, we can’t really find anything wrong. We have struggled to find anything to critique with the devices or the app. Everything works as intended and we are extremely pleased.

## Questions & Answers

**Q: Can you have more than one temp/humidity sensor in the same house running on the hub and app?**
A: Yes, You can. One Yolink hub can support more than 200 YoLink devices in real test. YoLink Hub covers more than 300 feet indoor and 1000 feet in the open air. Normally one hub is enough for one house.
Hope this answer is helpful to you

**Q: How often does the sensor check the temp and humidity for automation?  Is the sensor only checked after a certain number of minutes?**
A: The sensor updates the app each hour, minimum, but also updates if any of the following occur:

At least 0.9 F degree change over a period longer than 1 minute

At least 3.6 F degree change within 1 minute

At least 5% humidity changes over a period longer than 1 minute

The device reaches a pre-set high or low alert level (set by the user)

Or the SET button on the device has been pressed

**Q: Does this work with smartthings and do i need the yolink hub?**
A: Sorry, YoLink system is not compatible with smarrthings now, YoLink uses LoRa protocol and YoLink Hub is required. Thanks!

**Q: I see the YoLink hub is required for all smart features.  Is there an alternate way to just connect wifi and monitor from ios without the hub?**
A: No, YoLink hub is required. YoLink smart devices use a special wireless technology based on LoRa, which can offer extreme long range (1000 feet compared to 100 for WiFi, outdoors, line-of-sight) and superior obstruction penetration including concrete and metal, but they do not use your WiFi. They need to wirelessly connect to one of our hubs. Thanks!

### ⭐⭐⭐⭐⭐ Super easy setup, great app, really does work from inside a metal fridge. Alerts work well.
*by J***P on December 29, 2024*

Setup: Setup could not be easier. 1. Install app, 2. setup hub 3. add sensor(s). 4. Update Firmware. To make the hub setup quick and easy it's best to connect the hub to your router with an ethernet cable. The instructions have you scan a barcode on the hub using the app to register it, then power it up. It came online within a few seconds. WiFi can then be setup while it is connected via ethernet cable. If you wish to use WiFi power off and relocate the hub. It takes about 30 seconds to join WiFi after being powered up. Adding the sensor(s) is similar. Scan the barcode on the device with the app, then turn it on using a switch on the back of the unit. It will connect to the hub quickly. It is best to configure all the alerts and other settings while you have the sensor on a desk, then when the configuration is complete place the sensor where it is needed. Both the hub and sensor had the latest firmware as delivered which is awesome. Use: The LCD's still work even at freezer temperatures of -5f. The batteries in the LCD sensors will not last very long in a freezer. maybe 9 months, I have ordered some sensors that do not have an LCD and come with Lithium batteries good for 5 years. I'm really impressed how well the sensors work inside a freezer clear the other side of the house from the hub. It lives up to the hype. Sensors contact the hub about once per minute. App: The app is very good, there are some really detailed statistics you can view and there is an option to download data. I have included a screen shot of one of the charts showing a 24 hour view, Alerts: After setting thresholds, alerts can be sent via the app on your phone, an email, or SMS. SMS is limited to 15 SMS's per month but email works just fine and has no limit. Yolink Eco system: The number and variety of devices you can add to the hub is impressive. Given how easily the system and app works I'll be adding devices in the future. Highly recommended. Update:Jan 2026. The batteries showed half a charge after 14 months in a fridge. I replaced the alkaline AAA batteries with Energizer Lithium cells.
