Feature: Extend dumpSecure by device information

[CFenner]

dumpSecure is used to print diagnostic info in Home Assistant easily.

It would be nice, if the device data were provided here as well next to the data point.

It would especially be helpful to see to which device type, model and roles the data points belong.
