Wunderbar has its own limitations. There is no memory in the modules, so sensor values are not stored. Since the whole concept relies on the cloud service which is also the memory and data storage for the sensors, they must have a connection to the Internet all the time. And with only WIFI connection, use cases are stationary rather than mobile. While this could be evaded with additional mobile WIFI AP, Wunderbar starts to lose its meaning.
For fast and primitive prototyping, Wunderbar may sound as a a good choice, since it offers an easy way to gather sensor information from various spots with a single board. But problems with connection from sensor to phone and from sensor to master module, will rule out this device for us in most cases. The platform may function better in spaces with a good single WiFi network.
