​installation rtl-wmbus:

Download xaelsouth-rtl-wmbus-master.zip from Link: https://github.com/xaelsouth/rtl-wmbus

Unpack the source code

Open terminal to the top level directory rtl-wmbus-master and insert command:

make

Running:

Open terminal to the top level directory rtl-wmbus-master and then use one of these three options:

To save IQ-stream on disk and decode them off-line:
 
rtl_sdr samples.bin -f 868.9M -s 1600000cat samples.bin | build/rtl_wmbus

To run continuously:

rtl_sdr -f 868.9M -s 1600000 - 2>/dev/null | build/rtl_wmbus

To count "good" (no 3 out of 6 errors, no checksum errors) packets:

cat samples.bin | build/rtl_wmbus 2>/dev/null | grep "[T,C]1;1;1" | wc -l

Carrier-frequency given at "-f" must be set properly. With my DVB-T-Receiver I had to choose carrier 50kHz under the standard of 868.95MHz. Sample rate at 1.6Ms/s is hardcoded and cannot be changed.

samples2.bin is a "life" example with two devices received.
