A lot of the inspiration for this integration came from the excellent PowerCalc by bramstroker, without adapting code from PowerCalc I'd never have worked out how to add additional sensors to a device.

Huge thanks to @bmos for creating the issue form & automations for adding new devices.

Thanks to everyone who has submitted devices to the library.
