- Place inside a refrigerator or freezer, to prevent the loss of expensive refrigerated and frozen foods due to equipment failure or power loss
- Monitor the temperature of rooms or buildings without temperature control, for example, receive a low-temp alert before water pipes freeze
- There are numerous pet care applications:
- For reptile tanks (turn on a heat lamp if the temperature gets too low, or turn off the lamp if it gets too hot)
- Place one an outdoor dog house, to know if it’s too cold for them
- Place in a barn, to ensure your horses or livestock are comfortable and safe
- Receive alerts if sensor levels fall outside of your customized ranges

Q: Is there an Alexa command that will read out the temperature?
A: Yes, you can query Alexa. If your sensor name is ATTIC TEMP HUMIDITY, as it is in my own home, you can say "Alexa, what is the temperature of the attic temp humidity sensor?" And Alexa will return with "The attic temp humidity sensor temperature is 111 degrees."
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: 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.

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.

What I love about Yolink
1. Does not bog down your internet because only the base goes online
2. Amazing wall penetration and signal range
3. Super easy to set up devices
4. The software is relative, easy to understand and use
5. Dependable actions and alerts
6. No monitoring fees
7. Great customer service
I have an underground root cellar and a steel out building about 75 ft from my home which I thought there was no way the motion and temp sensors inside those buildings would be able to communicate with a base inside my home. But to my surprise they did. I was sold. I have since purchased several more motion sensors (interior and exterior), sirens, water leak sensors, thermostats, smoke alarms and some other devices. I purchased these several months ago and so far I am extremely pleased. The devices have been dependable and are not running through batteries quickly. I feel like I have an expensive system, but it was not expensive. Moreover, the customer service is exceptional. I had a question and was able to call and speak to someone knowledgeable and helpful immediately. I am so impressed I have recommended yolink to my family and friends.

I bought the YoLink Temperature and Humidity Sensor to automate my whole house fan, in combination with a YoLink mini plug and a new YoLink hub. Setup for all three devices was easy, the instructions were clear and the devices were immediately recognized by the app.
I created an automation to turn on the fan based on time and the high temperature alert on the temp sensor, and a second automation to turn the fan back off. Both have worked reliably so far.
The choices for a temperature monitor (sensor) that can trigger actions, even through IFTTT, is very limited. I was happy to find one that could not only do that, but also included a display AND was very economical. I will definitely order more temp/humidity sensors and wall plugs to further automate my home.
