Review: Pig to set up! - The hub is an absolute pig to set up but once you have done then it’s a great piece of kit for ensuring that I’m notified if the freezer out in the garage fails. I’m using the other sensor to keep an eye on the temperature in the freezer in the house. * important to note that it will initially tell you that no internet has been found - just ignore it and carry on with the set up*
Review: Works well as a warning system for monitoring your freezer temperature - Bought this to use in my freezer as an early warning system for loss of power or a freezer failure. It was simple to install and integrate with the free app. You can setup alerts to send email or SMS messages if the temperature goes above or below the thresholds you set. It also records the data so you can see over time how the temperature fluctuates which was interesting to see how much the temperature changes just by opening the freezer door for just a few seconds.

## 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!

### ⭐ Needs a hub to work with the app
*by L***A on 7 September 2024*

Very disappointed that there was no mention of needing a hub in the advert … needed this for a freezer in a garage so it had to work with an app. Returned. The refund was quick and efficient though!
