Niko Home Control Energy - My NHC bus system reads the smart meter data from the wireless bridge and my Niko Home app is showing that my energy consumption is far too much.

This situation may occur when your NHC bus installation is equipped with a measuring module and a wireless bridge that also reads from the smart meter.

In order to avoid the measurements from the digital meter and the measuring module being added together, you can use the NHC programming software to adjust the "measurement type" parameter to "sub-measurement" for this measuring module.
If the "measurement type" parameter is left at universal measurement, the measurement data will be added to the measurement data for the digital meter.

You may be able to use this measuring module to measure other circuits then too.
