.TH WMBUSMETERS 1
.SH NAME
wmbusmeters \- listen to wireless mbus radio traffic and relay the decoded telegrams to other software
.SH SYNOPSIS
.B wmbusmeters [options] <device>{:suffix} (<meter_name> <meter_type>[:<mode>] <meter_id> meter_key>)*
.B wmbusmetersd <pid_file>
.SH DESCRIPTION
Wmbusmeters acquires wmbus telegrams, decodes them and relays them to
some other software for further processing. It can for example listen
to radio traffic using dedicated wmbus dongles like (im871a amb8465 rfmrx2 cul d1tc)
or a generic software defined radio dongle (rtl_sdr).
After the received telegram has been decrypted and parsed, it can then
be relayed using a shell command, or stored in a log file. The shell
commands can for example relay the telegram using MQTT (eg
mqtt_publish) sent to a REST API (eg curl) or store it in a database
(eg psql).

.SH DEVICES
.TP
\fBauto:c1\fR detect any serially connected wmbus dongles and rtl_sdr dongles and configure them for c1 mode. (You do not need to use --c1 or --listento=c1 when suffixing the device with the linkmode.) Always try to use auto first.
.TP
\fBim871a:t1\fR look for an im871a dongle attached to any of the serial ttys and configure it for t1 mode.
.TP
\fBim871a[12345678]:t1\fR look for the im871a dongle with this particular id.
.TP
\fB/dev/ttyUSB0:amb8465:c1,t1\fR expect an amb8465 on this tty.
.TP
\fBrtlwmbus\fR use software defined radio rtl_sdr|rtl_wmbus to receive wmbus telegrams.This defaults to 868.95MHz, use for example \fBrtlwmbus:868.9M\fR to tune the rtl_sdr dongle to slightly lower frequency.
.TP
\fBrtlwmbus[alfa]:433M:c1,t1 rtlwmbus[beta]:868.9M:c1,t1\fR Use two rtlsdr dongles, one has its id set to alfa (using rtl_eeprom)
and the other set to beta. Alfa has an antenna tuned for 433M, beta has an antenna suitable for 868.9M.
.TP
\fB/dev/ttyUSB0:9600\fR read serial data from tty at 9600 bps, expects raw wmbus frames with the DLL crcs removed.
.TP
\fBstdin:rtlwmbus\fR read rtlwmbus formatted data from stdin.
.TP
\fBmyfile.txt:rtlwmbus\fR read rtlwmbus formatted data from this file instead.
.TP
\fBsimulation_xxx.txt\fR read telegrams from file to replay telegram feed (use --logtelegrams to acquire feed for replay)
.SH METER QUADRUPLES
.TP
\fBmeter_name\fR a mnemonic for your utility meter
.TP
\fBmeter_type\fR for example multical21:t1 (suffix means that we expect this meter to transmit t1 telegrams)
.TP
\fBmeter_id\fR one or more 8 digit numbers separated with commas, a single '*' wildcard, or a prefix '76543*' with wildcard.
.TP
\fBmeter_key\fR a unique key for the meter, if meter telegrams are not encrypted, you must supply an empty key: ""
.SH EXAMPLES
.TP
.TP
Wait for wmbus dongles to be inserted and then listen for c1 telegrams.
Print a summary of the telegram and whether wmbusmeters has a driver for decoding it.
% wmbusmeters auto:c1
Listen to C1 traffic using an im871a dongle attached to some tty.
% wmbusmeters im871a:c1
The im871a dongles have an id number that is printed when the dongle is started.
You can use this to specify which dongle to use for which linkmode.
% wmbusmeters im871a[12345678]:c1 im871a[22334455]:t1
.TP
Listen to both T1 and C1 traffic using rtl_sdr|rtl_wmbus and the standard frequency 868.95M, which
might need tweaking depending on the rtl_sdr dongle you are using.
% wmbusmeters rtlwmbus:868.95M
You can identify rtlsdr dongles this way as well. The id of the rtlsdr dongle is
set using rtl_eeprom. Assuming you want to listen to multiple frequencies, one dongle
has one type of antenna attached.
% wmbusmeters rtlwmbus[alfa]:433M:t1 rtlwmbus[beta]:868.9M:c1
.TP
Execute using config file /home/me/etc/wmbusmeters.conf and meter config files in /home/me/etc/wmbusmeters.d
% wmbusmeters --useconfig=/home/me
.TP
Start a daemon using config file /etc/wmbusmeters.conf and meter config files in /etc/wmbusmeters.d
% wmbusmetersd --useconfig=/ /var/run/wmbusmeters/wmbusmeters.pid
