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.

What's New

Version 2.11.10

Fixed a bug that crashes the temperature graph of Outdoor Probe for some users.

Ratings and Reviews



Once I found out that the outdoor probes don't associate unless the battery is at 3.6v. Easily fixed by swapping batteries with probes that had associated.
Support has been great. Very responsive. Firmware was updated specifically for a requirement I had.
Seem to be robust.
About to roll 20 sets out into the field for stress testing prior to roll out of many hundreds of sets if as successful as expected.
I'll write another review in a few weeks.

Needs refining


WirelessTag is a fantastic concept. Easy to set up easy to use. Just some daily annoyances that make it three stars.
Unable to silence annoying beeping alerts that occur when things have gone out of limits. I get notifications, great! I don't then need the app to beep when I open it. It's not a lot of use being beeped at if the error is not highlighted st the time.
Lots of times when looking a graphical data the previous items vowed are still ticked. Sometimes they are not. It's just inconsistent and annoying.
Temperature scheduling can be done by time schedule but not by occupancy without getting into java script yourself.
It would be nice if there was more flexibility about how parameters are set up to use for controlling temperature/humidity etc. Lots of potential and still a rapidly expanding sector in the IoT market.
Getting the app and the interface right is imperative otherwise less capable systems will dominate the market if they are easier to get and implement.

Best System out There


I have been using this app for the last 19 months and its by far the best out there at the moment. Jam packed with features. The PIR senosr sends instant Push alerts, emails to your Iphone/ipad. The range of the sensors are better than any other on the market, I have tried them all! The CAO support team are always adding and improving the app and system, where others only give one or two updates a year. You will not be disappointed.
