A more reasonably priced, but quality device (definitely not biliger China scrap). It shows the current consumption in watts, stores consumption in kw / h, and uptime. Plus min. and max. measured consumption in watts. There mains voltage and frequency are still displayed in current values.
You can set a basic rate (it then shows the consumption costs), but you do not! The display goes out when you look at it from the network, but do not scare - the last values are stored and can be displayed by pressing a button (it must have a permanently installed battery have).
