TellMeWhen is a fun and easy to use application which notifies you when a certain threshold has been reached or passed, based on rules you create yourself. It utilizes the relayr WunderBar sensors which gather information about temperature, humidity, light, proximity and noise levels. Just choose the measurement types you wish to be notified about, set a respective threshold and get notified whenever a threshold is exceeded. It's as simple as that!

TellMeWhen is an open source application, so you are more than welcome to download this repository and implement the code in your own Android or iOS / OSX projects. You are able to explore the code, review it and learn from it, however, please note that due to the use of an external database service, you will not be able to use the code as is. Due to security reasons we are unable to provide credentials for use of the database.

NOTE: The purpose of this application is to exemplify a useful and easy-to-implement manner of utilizing the WunderBar sensor modules. It is in no way intended for use in mission critical or life critical situations. Furthermore, delivery of push notifications cannot be guaranteed as they rely on the up-time and functionality of services external to the relayr platform.

For information about our sensors, have a look at our Making Sense of Sensors page.
