wmbusmeters/CHANGES

IMPORTANT CHANGES THAT MIGHT AFFECT YOU!

** No udev rules

Wmbusmeters new default behaviour is to NOT exit if no wmbus
device is found. It stays running all the time even if no
wmbus device is detected. As soon as a device is inserted
it will detect/configure and start using the device.

When reading stdin and files, then wmbusmeters will exit
as soon as there is no more data.

This means that the udev rules no longer are needed and must be
removed. This will be done automatically by the install script.

** Use stderr for logging, stdout for data.

wmbusmeters now uses STDERR as default for info/verbose/debug/trace output.
This will not affect you if you run wmbusmeters as a daemon,
but if you start wmbusmeters yourself you should check where stderr is going.
To use the old style add --usestdoutforlogging.

** New features

To list the shell envs for a meter do --listenvs=multical21
To list the fields avilable for a meter do --listfields=multical21
To list all meters do --listmeters
To search for a meter do --listmeters=water or --listmeters=multi

Version 0.9.36: 2020-09-08

Added support for detection of the proper driver
based on the manufacturer, media and version fields in the telegram.
This driver is printed when listening without specifying any meters.
The driver will be reported as unknown! for meters not yet supported by wmbusmeters.

Avandorp added support for the AquaMetro / Integra Topas Es Kr water meter.
Thanks Avandorp!

IzeCube added the Techem Compact V heatmeter!
Thanks IzeCube! Though we still need an example telegram for
testing this meter to prevent regressions. So it is currently
not as well supported as the other meters.

Version 0.9.35: 2020-08-23

Added support for alarms (shell command triggered)
and resetting of dongle when no telegrams have been received
for a preset time, or if there are communication errors
with the dongle.

Added support for the Waterstar M meter.

Bug fix for long term problem where wmbusmeters did not properly
shut down background rtl_sdr|rtl_wmbus pipeline.

Eric added support for the Multical 403. Thanks Eric!

Bibo made snapcraft fixes. The snap now builds properly! Thanks Bibo!

Version 0.9.34: 2020-07-09

Wmbusmeters should now properly handle
partially encrypted telegrams in mode 5 and 7.

The docker image now builds rtl_wmbus from the weetmuts
fork.

Bibo supplied code to auto-update the Docker hub README.

Version 0.9.33: 2020-07-01

Bibo made docker fixes. Now rtl_sdr, rtl_wmbus
and rtl_433 are part of the docker image. Thanks Bibo!

Version 0.9.32: 2020-06-30

Added support for the Lansen Smoke detector, Door/Window sensor
and Pulse counter.

The tool wmbusmeters-admin can now factory reset your amb8465 dongle.

Version 0.9.31: 2020-05-09

You can add comments in the conf and meter files.
A comment is a line that starts with #.

When using --format=fields you can now supply
--selectfields=id,total_m3 to print only the selected fields.
Run with --listfields to see all the avilable fields from a meter.

Improvements in the izar driver. Thanks Erwan!

Bug fixes in the amd8465 driver. Thanks Henry N.!

Version 0.9.30: 2020-04-22

Erwan added support for building on FreeBSD. Thanks Erwan!

Version 0.9.29: 2020-04-03

Re-add the wmbusmeters.service file so
that the daemon can be easily started without
udev rules. Check the README.

Version 0.9.28: 2020-03-08

Improved docker work, thanks Bibo!
Better shell scripts for installing and daemon mode,
in preparation for rpm packaging. Thanks Damian!

Version 0.9.27: 2020-02-26

Added support for the apator08 meter.
Fixed important bug that caused rtl_sdr to hang
when daemon was stopped/restarted.
Added support for both T1 and S1 modes for the CUL-dongle.
Added helpful messages when startup of daemon using rtl_wmbus
fails because /usr/bin/rtl_sdr or /usr/bin/rtl_wmbus are missing.

Version 0.9.26: 2020-02-07

Cinemarene added support for the Techem
FHKV Data III heat cost allocator. Thanks cinemarene!

Version 0.9.25: 2020-02-07

Fix bug i esyswm and ebzwmbe that printed zero values
for phase 2 and 3.

Version 0.9.24: 2020-02-06

Added the electricity meter eBZ wMB-E01 (ebzwmbe)
Fixed bugs with detecting the wmbus dongles.
Fixed bug in im871a driver that could
get out of sync and never receive any more telegrams.

Version 0.9.23: 2020-02-02

Added the electricity meters:
ESysWM-20 (esyswm) from EasyMeter
eHZ Generation P (ehzp) from EMH Metering

Added the water meter:
Q400 (q400) from Axis Industries.

Fixed a bug in the auto-start from udev that
prevented rtlsdr/rtlwmbus to work properly.

Version 0.9.22: 2020-01-19

Bibo added docker support. Thanks Bibo!
Checkout https://hub.docker.com/repository/docker/weetmuts/wmbusmeters

Version 0.9.21: 2020-01-19

Michal Bursa helped improve detection of a failing USB device
and added support for automatically starting multiple wmbusmeters
daemons if several dongles are inserted at the same time.
Thanks Michal!

Note! The wmbusmeters.service file is replaced with wmbusmeters@.service
and the contents of the udev file is changed. The install script
will properly install the new files and copy the old ones to ~/old.xxxx.backup files,
and tell the user how to reload the systemd and udev daemons.

Version 0.9.20: 2019-12-11

Added support for meterfilestimestamp
to get the effect of log rotation of the meter files.

Version 0.9.19: 2019-11-26

Chester4444 added support for the nanoCUL usb stick. Thanks chester4444!
Michal added a utility program (kem-import.py) to import KEM files. Thanks Michal!
Added support for the Diehl HYDRUS watermeter.
Added proper support for Multical302.

Version 0.9.18: 2019-11-10

Jacek added support for the Sappel/IZAR 868 meter. Thanks Jacek!

Version 0.9.17: 2019-11-03

Thanks to afl-fuzz I found and added
some (in retrospect pretty obvious)
missing checks to deal with
corrupted telegrams that crashed
wmbusmeters.

Now afl-fuzz does not trigger any crash
after running for a couple of minutes.
Lets fuzz more....

Version 0.9.16: 2019-11-03

Significant rewrite of serial.cc.
WMBusmeters can now specify stdin as <device>
and continuously read wmbus frames from stdin.
Either raw, or rtlwmbus formatted if stdin:rtlwmbus
is supplied as the <device>. Check the README for
more additions.

Version 0.9.15: 2019-10-20

Added Bmeter (rfmamb) and Lansen room sensors (lansenth).
Added support for the rfmrx2 dongle.
Added rawtty (eg /dev/ttyUSB0:38400) support for dongles
that only transmit raw telegrams on the serial port.
Added the ability to add static json data tailored for the meter.

Version 0.9.14: 2019-09-16

Added negative match rule for ids. You can now write:
id=78*,!7812345*,!78222222
which will match any meter whose id begins with 78
but not match any meter whose id begins with 7812345,
nor the meter with the exact id 78222222.

The order of the match rules does not matter.

Version 0.9.13: 2019-08-14

Fix bug that prevented rtl_wmbus to run inside daemon.

Version 0.9.12: 2019-08-12

Added experimental detection for apator162 where the total water consumption
is located within the proprietary data.

Version 0.9.11: 2019-06-20

Added --meterfilesnaming=(name|id|name-id)
to choose the file name written meter file.

Naming using id or name-id is necessary when a meter
specification listens to many different meters using id
wildcards.

Version 0.9.10: 2019-06-13

Update logrotate to trigger HUP when rotating log files.
This will re-initialize the serial connection to the usb dongle
and reload the config files as well.

Added reload command to systemctl.

Version 0.9.9: 2019-06-11

Added support for the signal HUP to trigger wmbusmeters(d)
to reload config files.

Added significantly better tracking of listening modes (C1,T1,S1 etc)
and notify the user if the wmbusmeters configuration would not hear
certain meters specified.

The apator162 meter can send either on c1 or t1. Thus if you have
an imst871a dongle that can only listen on one of c1/t1, then
you have to specify which link mode you expect the meter to use.
You do that by suffixing the meter type with the link mode, like
this: `apator162:c1`

If you do not do this, then wmbusmeters will assume that it must
listen to both c1 and t1 at the same time. Which might
be fine for amd8465 and rtlwmbus dongles, but not for imst871a.

Version 0.9.8: 2019-05-22

Added support for the EurisII heat cost allocator from Innotas.

Version 0.9.7: 2019-05-04

FeatureExpert added support for the Vario 451 heat meter. Thanks FeatureExpert!

New feature: --addconversions=GJ,L

This feature required a major rewrite of how meters print their data.
When the new option --addconversion=<unit> is used, then
any meter that outputs a compatible unit (like kWh) will have
the additional unit (like GJ) also added to to the json.

So if there is a total_energy_consumption_kwh in the json,
there will now also be a total_energy_consumption_gj

For the human readable output and the fields output, the kWh is replaced with GJ.

ATTENTION! change in json keys!

Some untyped json field names, like "flow_temperature":10 had to
change name to "flow_temperature_c":0 (so that if --addconversions=F
is used, then "flow_temperature_f":32 will be added.)

Version 0.9.6: 2019-04-27

Added support for the MK Radio 3 water meter. Thanks FeatureExpert!

Version 0.9.5: 2019-04-26

Improved install/uninstall scripts. Thanks Bibo!

Fixed wrong default sample frequency for rtl_wmbus. Thanks inc90!

Version 0.9.4: 2019-04-03

The device auto can now detect an rtlsdr dongle and start
rtl_sdr|rtl_wmbus properly. It can only detecht the rtlsdr
dongle if the new udev rule has been installed, which will
create the symlink /dev/rtlsdr when the dongle is inserted.

Added the meter vendor Echelon to the generic amiplus meter type.
(The Echelon meter seems to be a standard electricity meter with a
wmbus addon sourced from Develco.)

Version 0.9.3: 2019-03-20

Added initial support for the generic Tauron Amiplus electricity meter type (amiplus).
This is actually a generic meter type, that will match the meter vendors
that provide meters under the Amiplus brand to Taurn. The first vendor to
be supported is from Apator.

Added support for the at-wmbus-16-2 snap on meter (apator162).
Unfortunately it uses a vendor specific protocol,
that is merely wrapped inside a wmbus telegram. Lets hope
the offset to the consumption is stable between
meters of this type.

Verison 0.9.2: 2019-03-12

Add max_flow to the iperl meter. This is based
on a guess that the flow value is actually the max
flow.

Note! Since max flow was added to iperl, there is an extra
column in the human output and --format=fields output.
There is also "max_flow_m3h"="123" in the json output, but that does not
affect existing code depending on json.

Verison 0.9.1: 2019-03-05

Added support for listening to multiple meters
with the same key (or no key). Simple use '*'
as meter id, or make a comma separated list.

Added experimental support for listening to
--n1a to --n1f and an imst dongle. Might not work.

Version 0.9.0: 2019-02-26

Reading the meter settings from config files
in /etc is now supported.
Running wmbusmeters as daemon is now supported.
Using rtl_wmbus to receive wmbus messages from
rtl_sdr is work in progress.
Updated README
Updated some command line options robot is now format.
Listening to qcaloric now seems to work.
Added support for MacOSX.

Version 0.8.4: 2019-02-23

Add config files support and daemon mode.

Version 0.8.3: 2019-02-17

Add experimental support for qcaloric.

Version 0.8.2: 2019-01-27

Properly supports short C1 frames after it has received a long frame.
(Ie the format signature hash is properly calculated and used.)
Now properly extracts temperature from short frames!
Added support for Multical21 meters with max flow configuration.

Note! Since max flow was added to multical21, there is an extra
column in the human output and --format=fields output.
There is also "max_flow_m3h"="123" in the json output, but that does not
affect existing code depending on json.

Version 0.8.1: 2019-01-04

Fixed memory leak in shell invocation.
Improved dvparser to properly handle the supercom587 telegrams.
(It still does not extract all the data, but the data is properly parsed and chunked.)
Added address sanitizer to debug build.
Added static analysis check.sh.

Version 0.8: 2018-11-29

Multical21 now reports flow temperature and external temperature.

Version 0.7: 2018-11-23

David Mallon contributed the iPerl water meter! Thanks David!

Version 0.6: 2018-11-02

Added --shell command to invoke for example: mosquitto to send an MQTT message
or psql to insert received data into a database.

Added proper T1 telegram support. First meter to use T1 is supercom587.
A large part of the supercom587 message is not yet properly decoded.
However the important part, the total consumption, is correct.

Version 0.5:

Added difvif parser to extract as much as possible automatically
from the the telegram.

Added initial support for Omnipower electricity meter.

Version 0.4:

Added initial support for heat energy meter Multical302.
Restructured to source to more easily support multiple meters.

ATTENTION! There is a difference in the command line interface.
You must now proved the meter type. Thus for each meter you
supply quadruplets instead of triplets.

Version 0.3:

Added support for wmbus USB receiver Amber AMB8465.

Version 0.2:

Initial working release supporting wmbus USB receiver IMST im871a and the meter Multical21.
