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.
