    This is exactly what I needed to keep track of how hot and humid the server room is. I already had a base to detect water in the server room, so this was a great addition.

    Love it

    Reviewed in the United States on June 11, 2022

    Style: Without HubVerified Purchase

    I decided to buy the Yo-Link base station, 2 motion sensors, and 2 outdoor temperature sensors.
    One motion sensor is in the living room and is very sensitive and detects the slightest movement. The other sensor is in my mailbox. I get an instant notification, and email whenever there is movement in my apartment. I had mail stolen from me. It is nice to know when I get mail, or if someone is tampering with my mailbox. The mailbox is on the other side of my apartment building, probably at least 1,000 feet away. I was surprised my base can get a signal on my mailbox that it is so far away. I have an outdoor temperature sensor to tell me the current temperature outdoors, and an outdoor temperature sensor in my car. I can now get the temperature of my car on cold winter days when I use the remote start. I had troubles integrating it with Alexa, and haven't used it. So I am only giving it four stars. Using the Yo-Link app, and the notifications are fine with me though. I have an indoor temperature sensor that works fine, but I have not integrated any automation on it to turn on alexa enabled plug to run the air conditioner or heater at certain temperatures, but the feature is there. The only gripe I have, if I need to keep temperature records.. The temperature sensors only report to the base every 15 to 30 minutes. It will miss high and low temperatures for the day. The same thing with a car temperature, sometimes by the time I remote start my car… The car will already be warmed up by the next time the sensor reports to the base. It is probably built that way to save battery life. Also, I have set up an alert if the car reaches 110 or 120 degrees during the summer, to remind me to take out electronics that have batteries, or anything that can explode in high heat. The Yo-Link temperature and motion sensors have a wide variety of uses, good range, and overall I am satisified. Just had issues connecting it with Alexa.

    This is so much more reliable than Apple weather. I can actually know what the temp is at any time which is great in an area where the temps can swing a lot. Range is fine. I installed on the back leg of a deck post so it isn't in direct sunlight.

    Bought 11 months ago, and has worked flawlessly up until now. Manual well written with troubleshooting guide. Tried everything and could not get it to work. Reached out via email to customer service. Within 15 minutes got return email asking for the unit id. Replied back about an hour later. 10 minutes after that, customer service explained they are shipping out a new unit today. No fuss. This is what customer service is all about and SO REFRESHING to deal with a company that cares and replies so quickly. They have a great variety of sensors a few I have bought. App layout very user friendly. Bravo!

    Very accurate and easy to setup. For now, it's outside at mild temperatures 3 C and works great. Also reports humidity levels. I placed it at a spot of my house (west side) so it does not get direct sunlight and provides "real" temperature readings.

    Reviewed in Canada on May 19, 2023

    You need to purchase a hub for this piece. This keeps track of temperature and humidity in real time. We are farmers and this lets us know what the temperature was overnight in a graph. The thermometer sends data to the app every hour if the temperature doesn't change, or more often if there are bigger temperature fluctuations. When I get up in the morning I can tell if the temperature was below zero for 10 minutes or all night. You can set alarms to let you know about temperature changes or you can just check the app. The range is awesome. I have a tin roof on my house and this thermometer is at least 500 feet from my house.
