So HS3's Energy panel seems unusable. Only 1-2 devices seems to be read, and HS3 seems to read those just occasionally.

I see some other Energy plugins are available, but as far as I can see those rely on specific devices (energy monitors).

Are there any plugins capable of reading kw/h readings from plugin-modules? For instance fibaro modules report watts and kw/h, as well as some other brands.
