For some reason the processing of the data stopped today, it worked again once I restarted home-assistant. Any ideas why that would be?
Connection loss is not handled atm, which I think is what you are hitting here. I am not sure, but I think it is not implicitly handled by the asyncio protocol/transport. For serial this is less of an issue, but for tcp disconnects can happen more often. I am already looking into implementing this. Iāll let you know when you can test it.
Just to be sure, can you please check the logs to see if there are any disconnect errors.
Iāam a bit indisposed at the moment, it might take me a few days before I can look further into this.
I can say that no more disconnects have occurred since the first one.
When I have time I will give more feedback/ check the logs.
At my side, the new TCP connection is working like a charm (aside from some āNo line class found forā warnings like @SuperCyril mentioned). Iām using ser2net as a proxy to my USB (to serial) connected Smartmeter (Landis+Gyr ZCF110 (DSMR 4.2)).
@aequitas, in your commit, I saw that you explicitly enabled DEBUG logging for the dsmr_parser. I guess thisāll be reverted back to ERROR in the final release? It pollutes the logfiles quite a bit now 
Good to hear its working as expected. Logging will be set to error again in the release indeed. I am working on fixing reconnects, after that I will put it up for merge with HA.
@SuperCyril @AlexMekkering @ThinkPad @fversteegen
TCP & reconnect support, now also included V4 CRC checking:
If you could be so kind to test if this works for you.
Working at my end! Just a, stupid, question; I currently still use DSMR.py through custom_components shouldnāt I remove this and go to the official release?
Iām having some trouble with failing CRCs now at my end. I think V4 CRC calculation is incorrect and have issued https://github.com/ndokter/dsmr_parser/pull/13 which fixes it. Other than that, it works as expected (with adapted CRC calculation).
EDIT: Iāve issued https://github.com/ndokter/dsmr_parser/pull/15 now instead.
Is it possible to create a sensor that displays the total power consumption ?
like sensor.power_consumption_low + sensor.power_consumption_normal
Sorry for the late response. I think it should be easily doable with a template sensor: https://home-assistant.io/components/sensor.template/
Just to let you all (and especially @aequitas) know: this is now running flawlessly for several weeks at my end 
not a single issue or bad reading.
Hi all,
I have a question, it has not nothing to do with the component but more with the hardware:
I created my own RJ11 to USB cable (from this), and if I connect it to my Windows laptop and open a connection with putty, I can see the data fine.
But if I connect it to my raspberry pi and open a screen session, I only see a blank screen and the cursor moves around as if lines are displayed only they are empty linesā¦
Iāve tried a lot of settings, but canāt get it workingā¦ Anyone knows what the problem might be?
Thanks in advance!
This question is indeed a bit off topic for this thread, but ok. My best bet is that your cable is set to the wrong baudrate. You can check this by issuing
sudo tty -F /dev/ttyACM0 9600
Which is for 9600 baud. Usually it is either 9600 57600 or 115200. Of course: change ā/dev/ttuACM0ā to the right port name.
thanks, tried that already (as all other settings, databytes, stopbits, parity, etcā¦) but no joyā¦ I will get another usb to serial converter, what kind of converters are you using?
Just encountered the same problem with /dev/ttyAMA0 access rights for modbus module on RaspberryPi, your solution worked perfectly, thank you.
@aequitas thank you very much for all your work - it is really nice to see realtime updates of my power usage - since I have a DSMR5 meter it is even updated every second ;-).
Is it possible to upgrade your DSMR sensor to use the latest (>= 0.8) dsmr_parser?
Currently you use 0.6 and that has no support yet for DSMR5. I have received the ISKRA AM550 (DSMR5) and I was only able to get my setup working after I disabled the validate_telegram_checksum in parsers.py from the dsmr_parser. I expect that after upgrading to 0.8 that issue should be solved since it was addressed in version 0.8.
BTW @piotr I have manually built the P1 wifi gateway (I had an ESP12E laying around) from http://www.esp8266thingies.nl/wp/ and it works smoothly with @aequitas plugin.
I added it as a task, I probably can get to it in the next few days. https://github.com/home-assistant/home-assistant/issues/6218
Iām not sure if the question is allowed, if not please remove. 
Is there anyone in the Netherlands who can help me with a wireless hardware solution that works with this code?
My HASS PC is to far away from the P1 port so USB is not an option.
Maybe an easy manual or a address to buy one, thanks in advance 
For the creators of the code, awesome work, thanks. 
I use this (see link below) but still did not have a chance to test. I think there are people also using this, pls check the whole threat.
