Hi! I've archived this repo and @daniel-jong is maintaining a fork of the DIY, so please adjust the url for a more recent and maintained version :) I doubt that it's still needed with the new [project by Marcel Zuidwijk](https://github.com/zuidwijk/dsmr/)) but for completeness :)

A sensor platform for Dutch Smart Meters which comply to DSMR (Dutch Smart Meter Requirements), also known as 'Slimme meter' or 'P1 poort'.
- Currently support DSMR V2.2, V3, V4, V5, V5 Belgian and V5 Smarty through the dsmr_parser module by Nigel Dokter.
- For official information about DSMR refer to: DSMR Document
- For official information about the P1 port refer to: P1 Companion Standard
- For unofficial hardware connection examples refer to: Domoticx
This integration is known to work for:
- Iskra ME382 / MT382 (DSMR 2.2)
- ISKRA AM550 (DSMR 5.0)
- Landis+Gyr E350 (DMSR 4)
- Landis+Gyr ZCF110 / ZM F110 (DSMR 4.2)
- Kaifa E0026
- Kamstrup 382JxC (DSMR 2.2)
- Sagemcom XS210 ESMR5
USB serial converters:
- Cheap (Banggood/ebay) Generic PL2303
- Smartmeter Webshop
- SOS Solutions
- AliExpress

Optional configuration example for ser2net:
# Example /etc/ser2net.conf for proxying USB/serial connections to DSMRv4 smart meters
2001:raw:600:/dev/ttyUSB0:115200 NONE 1STOPBIT 8DATABITS XONXOFF LOCAL -RTSCTS
or
# Example /etc/ser2net.conf for proxying USB/serial connections to DSMRv2.2 smart meters
2001:raw:600:/dev/ttyUSB0:9600 EVEN 1STOPBIT 7DATABITS XONXOFF LOCAL -RTSCTS
Docker users have to allow Docker access to the device by adding --device /dev/ttyUSB21:/dev/ttyUSB21 to the run command:
$ docker run --device /dev/ttyUSB0:/dev/ttyUSB0 -d --name="home-assistant" -v /home/USERNAME/hass:/config -v /etc/localtime:/etc/localtime:ro --net=host {{ site.installation.container.base }}
Options
To configure options for DSMR integration go to Configuration >> Integrations and press Options on the DSMR card.
Time between updates
Typically the smart meter sends new data every 5-10 seconds. This value defines the minimum time between entity updates in seconds. Setting this value to 0 will update entities each time data is received from the smart meter.
Technical overview
DSMR is a standard to which Dutch smartmeters must comply. It specifies that the smartmeter must send out a 'telegram' every 10 seconds (every second for DSMR 5.0 devices) over a serial port.
The contents of this telegram differ between version but they generally consist of lines with 'obis' (Object Identification System, a numerical ID for a value) followed with the value and unit.
This module sets up an asynchronous reading loop using the dsmr_parser module which waits for a complete telegram, parser it and puts it on an async queue as a dictionary of obis/object mapping. The numeric value and unit of each value can be read from the objects attributes. Because the obis are know for each DSMR version the Entities for this integration are create during bootstrap.
Another loop (DSMR class) is setup which reads the telegram queue, stores/caches the latest telegram and notifies the Entities that the telegram has been updated.
