Smart sockets that can not only be switched via software but also measure consumption are very useful aids. Especially in conjunction with photovoltaics, and even if it is “only” a balcony power plant, the energy can be used much more efficiently if configured correctly.

But it doesn’t always have to be smart – on the contrary:
Sometimes, an adapter socket should not be smart at all. Instead, it should be able to withstand full power, which is usually not the case with smart sockets. 10 A at 230 volts is the rule rather than the exception, which reduces the maximum possible power consumption of the plugged-in device by more than a third.

Some time ago, Kaufland offered an energy cost and feed-in meter from Schwaiger, a company actually known for satellite technology for a mere €7.99 per unit. The item number is “NET0010” and you can find the device directly at Schwaiger here. The instructions for use are also available from the manufacturer.

What can this inexpensive measuring socket do better than many others?

The position of the LCD display is really good and: rotatable!

16A at 230 volts equals a full 3680 watts, with no limitations on possibilities. I am currently using it to measure the power requirements of our Proxmox servers, where a simple display with as little power consumption as possible is sufficient. Otherwise, the ideal application is temporary or permanent local measurement – well suited for things like idle consumption or troubleshooting.

This adapter has been running smoothly for a few years now and is highly recommended for anything that doesn’t need to be smart at the price asked. There are many similiar products available*.
