.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> (<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)
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 OPTIONS
\fB\--addconversions=\fR<unit>[,<unit>] add conversion to these units for json and shell envs (GJ,F)

\fB\--debug\fR for a lot of information

\fB\--exitafter=\fR<time> exit program after time, eg 20h, 10m 5s

\fB\--format=\fR(hr|json|fields) for human readable, json or semicolon separated fields

\fB\--listento=\fR<mode> listen to one of the c1,t1,s1,s1m,n1a-n1f link modes.

\fB\--listento=\fR<mode>,<mode> listen to more than one link mode at the same time, assuming the dongle supports it.

\fB\--c1 --t1 --s1 --s1m --n1a ... --n1f\fR listen to c1,t1,s1,s1m,n1a-n1f telegrams.

\fB\--logfile=\fR<dir> use this file instead of stdout

\fB\--logtelegrams\fR log the contents of the telegrams for easy replay

\fB\--meterfiles=\fR<dir> store meter readings in dir

\fB\--meterfilesaction=\fR(overwrite|append) overwrite or append to the meter readings file

\fB\--meterfilesnaming=\fR(name|id|name-id) the meter file is the meter's: name, id or name-id

\fB\--oneshot\fR wait for an update from each meter, then quit

\fB\--separator=\fR<c> change field separator to c

\fB\--shell=\fR<cmdline> invokes cmdline with env variables containing the latest reading

\fB\--shellenvs\fR list the env variables available for the meter

\fB\--useconfig=\fR<dir> load config files from dir/etc

\fB\--verbose\fR for more information

.SH DEVICES
.TP
\fB/dev/ttyUSB0\fR to which an im871a or amb8456 dongle is attached

.TP
\fBauto\fR look for /dev/im871a or /dev/amb8465 or /dev/rtlsdr (these will only show up automatically if the appropriate udev rules have been installed)

.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
\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 multical21/flowiq3100/supercom587/iperl/multical302/omnipower/qcaloric/apator162/amiplus
(Can be suffix with :<mode>, eg apator162:t1 to tell wmbusmeters that you expect only t1 telegrams.
This is necessary since an apator162 can be configured to send either c1 or 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

Listen to T1 traffic using a wmbus dongle attached to ttyUSB0.

% wmbusmeters --t1 /dev/ttyUSB0

.TP
Listen to C1 traffic and assume that a wmbus dongle is either /dev/im871a or /dev/amb8465 or /dev/rtlsdr

% wmbusmeters --c1 auto

.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

.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

.TP
An example wmbusmeters.conf:

.nf
loglevel=normal
device=auto
logtelegrams=false
meterfiles=/var/log/wmbusmeters/meter_readings
meterfilesaction=overwrite
logfile=/var/log/wmbusmeters/wmbusmeters.log
shell=/usr/bin/mosquitto_pub -h localhost -t "wmbusmeters/$METER_ID" -m "$METER_JSON"
.fi

.TP
An example wmbusmeters.d file:

.nf
name=MyTapWater
type=multical21
id=12345678
key=001122334455667788AABBCCDDEEFF
