The program receives and decodes C1 telegrams
|
|
|
|
(using the wireless mbus protocol) to acquire
|
|
|
|
utility meter readings. No configuration file
|
|
|
|
exists, you change main.cc, recompile and run
|
|
|
|
to output the values you are interested in,
|
|
|
|
typically to log and be processed by another tool.

(After you insert the im871A USB stick, do:
|
2017-08-09 10:02:42 +00:00
|
|
|
|

chown me:me /dev/ttyUSB0

|
|
|
|
2017-08-09 10:00:11 +00:00
|
|
|
to avoid having to run the program as root.)
|
|
|
|
|
|
|
|
Currently only supports the USB stick receiver im871A
|
|
|
|
and the water meter Multical21. The source code is modular
|
|
|
|
and it should be relatively straightforward to add
|
|
|
|
more receivers (Amber anyone?) and meters.

Code can print total water consumption! But everything else is
|
|
|
|
missing. CRC checks anyone? :-) Don't rely on these measurements
|
|
|
|
for anything really important!
