The powerspectrum plugin

Available since version: 0.10.0

Description

The powerspectrum plugin and widget creates a graph to show the power spectral data that the Enertex Smartmeter can send on the KNX bus.

Settings

For a general understanding of how the configuration files are structured and what elements and attributes are it is recommended to read this section first: visu-config-details.

The behaviour and appearance of the powerspectrum plugins can be influenced by using certain attributes and elements. The following tables show the allowed attributes and elements and their possible values. The screenshots show, how both can be edited in the editor.

Attributes underlined by ..... are mandatory, all the others are optional and be omitted.
