/*

This example defines three datapoints.
The first two are TEMPL type datapoints and have their own callback.
When no specific callback is attached to a datapoint, it uses the global callback.

Note the difference in return value between the callbacks:
for tempCallback uses value.getFloat() as TEMPL datapoints return a float.
globalCallback uses value.getString(char*,size_t). This method is independent of the returned type.
