Release Battery/Temperature smartapp dump to mySQL database

Hey there,

The data collection is only reading the DTH values so this has no impact on the physical sensors.

The setup is described on this GitHub link:

Fee free to adapt to you own usage like adding more type of sensors to monitor or different information to record.
