Note: If HWg-PWR does not find any connected meters, re-check the M-Bus connection (in
particular its polarity) and the baudrate and parity configuration, or try to look up these
values in the documentation of your meter. Repeat the search until you find all meters.
When only some of the meters are found but not all, the problem may be in different
communication parameters. Repeat the search with other Serial Baudrate and Serial Parity
settings.
