If you have a wine cellar in your house, you probably know that keeping it at constant temperature is important.

If it is cold at night but hot during the day, the air inside each bottle contracts and expands, gradually loosen the cork, spoiling the wine inside. Temperature variation as little as 3°C can be bad for your wine. 

If air humidity is too low, the cork can dry up, if too high, mold can grow. While human prefers dryer climate, the optimum humidity for wine storage is between 60% and 80%. 

How do you check that your wine cellar temperature is stable enough, and humidity is always optimal, without staring at the thermometer 24/7? And what can do you if it is not? 

You will need:

Needless to say, you will get super easy to use temperature/humidity graphs (Example from actual wine cellar #1, #2, #3, #4, #5) by just placing the Wireless Tag inside the cellar, from which you can check daily temperature and humidity variations. 

First enable temperature and humidity monitoring from the Wireless Tag main interface (from clicking on the temperature and humidity buttons). 

Now you can use these IFTTT applets: turn on heat, turn off heat, turn on humidifier, turn off humidifier.  KumoApp, however, will provide more flexibility.  


After setup, you launch either iPhone or Android app for Wireless Tag while connected to the same WiFi as your WeMo plug. It should find the WeMo, and allows you to link the WeMo (from "+Associate" screen) so that it can be used by KumoApps.

Click the green KumoApp button. You will see these screens. Pick an app (rules) that allows you turn on a Wemo switch when it is too cold, and off when back to normal. There is also apps to turn on a Wemo switch when it is too dry, and turn it off when back to normal. Some KumoApps allows you to delay the turning on. You can also fine adjust the temperature monitoring in main interface to only trigger the KumoApp when N successive too cold/too dry readings are obtained.

When KumoApp was first released 5 years ago, it had been much less reliable. Since then, we have been continuously improving its reliability, and now KumoApp is entirely different from that time. We are confident to recommend using it this way.
