Last week, someone from the network operator was here and wanted to install an intelligent measurement system. In the process, he found out that there was no space in the cabinet for the additional hardware needed because the APZ field reserved for the network operator was blocked by a small submeter for our heat pump. He then left without accomplishing anything and said we should schedule a new appointment once we have relocated the meter and freed up the field again. It’s annoying that our electrician doesn’t have time for such small stuff before summer. grin
