YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage, Smartphone Alerts - Hub Required

I got this to monitor the temperature in a storage shed. I wanted to link it with Alexa and set up a routine to turn on a vent blower at a certain temperature range. Turns out this links with Alexa fine, but only shows the temperature. Thats it. The humidity does not even show in Alexa. You cant even ask Alexa to state the temperature from it, you have to manually look at it. And Alexa will not recognize it to set up a routine like I wanted either for some reason. Well, at least I can monitor the temperature and get a notification from the Yolink app when the temperature gets too high. Keeping it because I might use it elsewhere, but Ill be buying something else to trigger the vent blower.

I ordered an additional temperature sensor as I have a few already and I am happy with them. I also have some water leak sensors. I was having a little trouble setting it up and contacted customer service and they walked me through it as they always do -I am very happy with the product and the service!

I like the compact size of the device. Its on the back deck right now, where the temperature is a cool 7.7 F. (at 8:40) and the YoLink says it was 1.4 F at 7:55 and that time difference makes it hard to know if the YoLink is correct. But, early this morning I did see it 0.2 F displayed on my phone, and the local weather station (down the street) recorded a low this morning of 0.6 F. So, I think its working pretty well. Before I put this outside on the deck, I noticed that changing from C to F or F to C, would instantly display the current temperature (on the LCD and the app). So, it can be forced to sample, display and send data to the app. The only negative I can see right now, is the slow sample rate that Im seeing when the sensor is outdoors. I can ask Alexa what is the temperature in the Prius and she says The Prius Temperature is 5.7 Degrees. But, I dont yet know how to create an Alexa routine that can trigger an action when the temperature is <= 5.0 F.. So, this sensor isnt very useful yet. Maybe I should see what IFTTT can do for me. ~~3/26/2023 I ordered a Yolink SpeakerHub. I can trigger a Yolink Routine when the temperature hits an alarm limit! I set the limit for 90F and put in a south facing window. When the sun comes bright, it gets up to 90F and commands my Yolink speaker to say (custom) Hey Google, turn on the Inverter. My Google Hub, controls Meross Outlet 120Vac switches. The switch named Inverter turns on, drives a relay that activates my 3000W Sine Wave inverter. The Alert Interval is set for 60 mins. (if the sun is still warm, we get a new Alert every hour). My Merross switch is set to run max run time of 65 mins. If it gets a restart every 60 mins, it keeps the inverter running until the sun is about to go down. My inverter is driven by a 48vdc battery bank, but when its charged, I can use the 800w solar panels to run some the loads in the basement. Freezer, Fios system, inhouse ethernet gear and a PlaneFinder tracking system. The main loads are the sump pumps. When the basement floods! Like we just had when all the snow melted. Both Alexa and Google speakers can work to control the solar inverter, Im using a Google speaker hub, because it was already installed near the Yolink Speaker Hub.

works great amazing range

Works great. I can now monitor the temperature in my house wherever I am as long as I have internet.

Easily monitor temperature when not home, alert if it exceeds limits. Very easy to set up with the app.

I have 7 of these that I use. All but one seem to function with good accuracy. I have one that seems to be off from other thermometers by almost 5 degrees at times. Overall a good product with pretty good reliability.

I have several of these units monitoring high and low temperatures. They work well, even when cold; they alert me when the freezer gets too warm. Alexa integration is lacking, however; you can’t trigger events in Alexa when the limits are exceeded. The in-app alerts work, but aren’t as flexible.

I stumbled upon YoLink while searching on the internet for separate smart temperature and smart humidity sensors for several automation projects in my home, so I was excited to find they have a temperature/humidity sensor (in a single unit). As an electronics and home automation enthusiast, I have since been adding them all over my home. Here are a couple pictures, and here are some applications Ive tried out or will be implementing in my home: Automating control of exhaust fan in bathroom - turn on fan before the room steams up during a shower/bath Keeping an eye on a fridge on its last leg Monitoring the temp and humidity of a bearded dragon tank. Both are very important. I also have automations to turn the heat lamp on if it gets too cold. My daughter, its her pet, has the app installed and receives notifications of problems with the temp or humidity. I also have a general tank light on a smart plug, on a schedule. I am going to be installing a whole house fan soon, and I want to use these, in most rooms of the house, to slow or turn off the fan, as well as to control ceiling fans in the bedrooms (to turn them down or off as it starts to get too cold at night, with the WHF running all night, otherwise). The ceiling fans are on Lutron Caseta switches, but the Alexa and IFTTT.com integration allows for automations that include multiple brands. Very flexible! I can see additional uses for this, keeping an eye on a wine cellar, a leaky basement (in conjunction with their Water Sensor), an unoccupied property or building or room subject to damage from freezing, extreme heat or humidity (and mold and other resulting issues). Thats a great price, too. Which is good, because I plan to get more of them!

Easy to instal - includes downloadable manuals and videos.
