Nigel 594db890fe Merge pull request #110 from debug-richard/master
Adds support for the Sagemcom T210-D-r smart meter
2022-10-16 12:49:55 +02:00
Richard Schleich 09f4afcada Adds support for the Sagemcom T210-D-r smart meter installed by Austrian grid operators.
The smart meter uses the DSMR/P1 standard and embeds the data in an encrypted and authenticated "DLMS General Global Cipher" frame.
The encryption/decryption is handled by the "dlms_cosem" lib.
Test cases are included.
Adds OBIS codes for reactive energy.

Client module usage
@@ -42,10 +39,136 @@ process because the code is blocking (not asynchronous):
for telegram in serial_reader.read():
print(telegram) # see 'Telegram object' docs below
**Socket client**
Read a remote serial port (for example using ser2net) and work with the parsed telegrams.
It should be run in a separate process because the code is blocking (not asynchronous):
.. code-block:: python
from dsmr_parser import telegram_specifications
from dsmr_parser.clients import SocketReader
socket_reader = SocketReader(
host='127.0.0.1',
port=2001,
telegram_specification=telegram_specifications.V4
)
for telegram in socket_reader.read():
print(telegram) # see 'Telegram object' docs below
**AsyncIO client**
To be documented.
For a test run using a tcp server (lasting 20 seconds) use the following example:
.. code-block:: python
import asyncio
import logging
from dsmr_parser import obis_references
from dsmr_parser.clients.protocol import create_dsmr_reader, create_tcp_dsmr_reader
logging.basicConfig(level=logging.INFO, format='%(message)s')
HOST = MY_HOST
PORT = MY_PORT
DSMR_VERSION = MY_DSMR_VERSION
logger = logging.getLogger('tcpclient')
logger.debug("Logger created")
def printTelegram(telegram):
logger.info(telegram)
async def main():
try:
logger.debug("Getting loop")
loop = asyncio.get_event_loop()
logger.debug("Creating reader")
await create_tcp_dsmr_reader(
HOST,
PORT,
DSMR_VERSION,
printTelegram,
loop
)
logger.debug("Reader created going to sleep now")
await asyncio.sleep(20)
logger.info('Finished run')
except Exception as e:
logger.error("Unexpected error: "+ e)
asyncio.run(main())
Note the creation of a callback function to call when a telegram is received. In this case `printTelegram`. Normally the used loop is the one running.
Currently the asyncio implementation does not support returning telegram objects directly as a `read_as_object()` for async tcp is currently not implemented.
Moreover, the telegram passed to `telegram_callback(telegram)` is already parsed. Therefore we can't feed it into the telegram constructor directly as that expects unparsed telegrams
However, if we construct a mock TelegramParser that just returns the already parsed object we can work around this. An example is below:
.. code-block:: python
import asyncio
import logging
#from dsmr_parser import obis_references
#from dsmr_parser import telegram_specifications
#from dsmr_parser.clients.protocol import create_dsmr_reader, create_tcp_dsmr_reader
#from dsmr_parser.objects import Telegram
logging.basicConfig(level=logging.INFO, format='%(message)s')
HOST = MY_HOST
PORT = MY_PORT
DSMR_VERSION = MY_DSMR_VERSION
logger = logging.getLogger('tcpclient')
logger.debug("Logger created")
class mockTelegramParser(object):
def parse(self, telegram):
return telegram
telegram_parser = mockTelegramParser()
def printTelegram(telegram):
try:
logger.info(Telegram(telegram, telegram_parser, telegram_specifications.V4))
except InvalidChecksumError as e:
logger.warning(str(e))
except ParseError as e:
logger.error('Failed to parse telegram: %s', e)
async def main():
try:
logger.debug("Getting loop")
loop = asyncio.get_event_loop()
logger.debug("Creating reader")
await create_tcp_dsmr_reader(
HOST,
PORT,
DSMR_VERSION,
printTelegram,
loop
)
logger.debug("Reader created going to sleep now")
while True:
await asyncio.sleep(1)
except Exception as e:
logger.error("Unexpected error: "+ e)
raise
if __name__ == '__main__':
try:
asyncio.run(main())
except (KeyboardInterrupt, SystemExit):
logger.info('Closing down...')
