ᐅ Measuring the electricity consumption of the house

Alternatively, a second meter can be installed after the utility provider’s meter. It can usually be fitted quite compactly into the electrical cabinet at first glance.

I hope you understand that your own S0 meter will measure significantly different values compared to the provider’s meter. Standard S0 meters are designed only for specific types of loads. If your loads don’t match these specifications, your S0 meter is likely to give inaccurate readings. This is quite common in residential buildings. Utility meters are generally designed for a much wider range of loads and usually provide more accurate measurements. If you install your own sub-meter, make sure that inductive loads and loads from ballasts with dimmers are measured correctly.

Otherwise, search for "Smart Meter often measures incorrectly." This should help you understand the issue of differing measurement results when using two meters.

Oh, is it really that bad? I would have assumed that a MID-certified meter would be good enough. If the energy supplier doesn’t have a decent meter, I will probably install one of these anyway. I’m more concerned about the relative energy consumption.

This is done thousands of times. No problem.
But yes, it would of course be easier to take the consumption from an existing meter. That’s clear.

Is KNX involved? Then you could consider a meter from Lingg & Janke.

I just count the red blinking.

Also an option, but for now better to install a new meter with S0 interface. Currently, there is only a very old one with a spinning disk. Implementation will have to wait a bit longer.
