This app remotely controls "Wireless Sensor Tags" cloud temperature/humidity/motion recording, monitoring and lost-item-finder device. Use it to make each tag beep (helps find lost items) and receive push notifications when each tag detects motion, door/window open/close, water presence, temperature or humidity exceeding normal range. Cloud-record temperature and humidity graphs, view them anywhere with Internet, and get notified when temperature or humidity exceeds user defined normal range.

"Wireless Sensor Tags" are integrated with WeMo switches/LEDs, various Internet-connected thermostats and IFTTT. Multiple "KumoApp" automation scripts can be written from web interface and configured inside the app to allow automated rules using information from Tags sensor data, chosen phones location data, and more, to trigger WeMo devices and thermostats.

Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life. This applies only if you install and enable KumoApp automation scripts that use/monitor your phone's location.

No more cameras ;(

Peace of mind knowing the beautiful fish I've caught is frozen and will stay that way till I'm ready to enjoy. An alert if power or freezer fails and while I'm gone and I can have a friend bring ice... Lots of ice!

Temperature tracking


This has been great for tracking steam radiator temps and seeing which radiators get hot first. Now I want more sensors to get ambient room temp and outdoor temp to compare.

Great product


Edit April 2017, developers are releasing new features fairly often and my sensors are working with relatively little issues. Still happy with the system!

If you like data and smart home automation...this app and the sensors are great for just that!

Edit June 2016: my review below was answered VERY quickly. The developers added every detail that I requested. I am very happy and appreciate the responsiveness!

My next request is for additional smart control products to be supported such as the TP link wifi switches. Also I would like to see a waterproof reed sensor and PIR sensor.

April 2016:
Looking for a new feature to be added. I would like the ability to swipe on a notification on the lock screen and a "pause for an hour" button appears. Ideally the time frame could be configurable for each sensor. Also this button should be available on the Apple Watch when the notification appears there. Also another button (I believe you can do two) to disarm the sensor for a configurable amount of Time as well. This way I can stop notifications if I am in/out of the back door, during a specific time period or disarm the tag from affecting other smart items in the house.

I really hope this is a feasible feature that can be added.
