Ok, now it is time to program.
|
||||
|
||||
To add a meter type, make a copy of meter_supercom587.cc to
|
||||
meter_mymeter.cc and add your meter to LIST_OF_METERS in meters.h
|
||||
and add the driver lookup values (mfct,type,ver) to METER_DETECTION.
|
||||
To add a meter type, make a copy of meter_supercom587.cc to meter_mymeter.cc
|
||||
(No other file needs to be changed, not even the Makefile.)
|
||||
|
||||
Add the line $(BUILD)/meter_mymeter.o \
|
||||
to the Makefile.
|
||||
|
||||
In meter_mymeter.cc, search and replace supercom587 for mymeter
|
||||
possibly adding a new meter type in meters.h if your meter is not a
|
||||
water meter and inheriting from that new meter type instead.
|
||||
Change all supercom587 strings to mymeter.
|
||||
|
||||
Build with address sanitizer and gdb debug info:
|
||||
make DEBUG=true

Run your code:
|
||||
./build_debug/wmbusmeters simulation_mymeter.txt

|
||||
Now its time to change processContent.
|
||||
Some meters contain values that can be found using findKey:
|
||||
if(findKey(MeasurementType::Unknown, ValueInformation::Volume, 0, 0, &key, &t->values)) {
|
||||
extractDVdouble(&t->values, key, &offset, &total_water_consumption_m3_);
|
||||
t->addMoreExplanation(offset, " total consumption (%f m3)", total_water_consumption_m3_);
|
||||
}
|
||||
|
||||
Some meters use vendor proprietary fields, typically error codes,
|
||||
those are found with:
|
||||
extractDVuint24(&t->values, "03FD17", &offset, &info_codes_);
|
||||
t->addMoreExplanation(offset, " info codes (%s)", status().c_str());
|
||||
|
||||
Add any addPrint:s in the constructor to get your decoded values into the json.
|
||||
|
||||
Now test your code:
|
||||
./build_debug/wmbusmeters --format=json simulation_mymeter.txt Water MyMeter 12345678 <key>

|
|||
(Do the daemon reload command if such is requested.)
|
||||
sudo systemctl start wmbusmeters.service
|
||||
|
||||
Eventually we have to add a regression test for MyMeter. The regression tests
|
||||
are really really important! This is done by adding a telegram in simulations/simulation_t1.txt
|
||||
and typically updating tests/test_t1_meters.sh and tests/test_listen_to_all.sh
|
||||
|
||||
You can always email me one of your telegrams and I can help you add it to the regression tests.
|
||||
I typically anonymize the telegram by changing the id to something random and it is stored
|
||||
decrypted in the simulations file, so no key sharing is necessary.
|
||||
Update the regression tests in the end of meter_mymeter.cc
