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 and V4 through the [dsmr_parser](https://github.com/ndokter/dsmr_parser) module by Nigel Dokter.

For official information about DSMR refer to: [DSMR Document](http://www.netbeheernederland.nl/themas/hotspot/hotspot-documenten/?dossierid=11010056&title=Slimme%20meter&onderdeel=Documenten)

This component is known to work for:

- Iskra ME382 / MT382 (DSMR 2.2)
- Landis+Gyr E350 (DMSR 4)
- Landis+Gyr ZCF110 / ZM F110 (DSMR 4.2)
- Kaifa E0026
- Kamstrup 382JxC (DSMR 2.2)

,USB serial converters:

- Cheap (Banggood/ebay) Generic PL2303
- https://sites.google.com/site/nta8130p1smartmeter/webshop
- https://www.sossolutions.nl/slimme-meter-kabel

And Serial to network proxies:

- ser2net - http://ser2net.sourceforge.net/

```yaml
# Example configuration.yaml entry
sensor:
  - platform: dsmr
```

Configuration variables:

- **port** string (*Optional*): Serial port to which Smartmeter is connected (default: /dev/ttyUSB0 (connected to USB port)). For remote (i.e. ser2net) connections, use TCP port number to connect to (i.e. 2001).
- **host** string (*Optional*): Host to which Smartmeter is connected (default: '' (connected via serial or USB, see **port**)). For remote connections, use IP address of host to connect to (i.e. 192.168.1.13).
- **dsmr_version** string (*Optional*): Version of DSMR used by meter, choices: 2.2, 4 (default: 2.2).

Full configuration examples can be found below:

```yaml
# Example configuration.yaml entry for USB/serial connected Smartmeter
sensor:
  - platform: dsmr
    port: /dev/ttyUSB1
    dsmr_version: 4

group:
  meter_readings:
    name: Meter readings
    entities:
      - sensor.power_consumption_low
      - sensor.power_consumption_normal
      - sensor.power_production_low
      - sensor.power_production_normal
      - sensor.gas_consumption
```

```yaml
# Example configuration.yaml entry for remote (TCP/IP, i.e. via ser2net) connection to host which is connected to Smartmeter
sensor:
  - platform: dsmr
    host: 192.168.1.13
    port: 2001
    dsmr_version: 4

group:
  meter_readings:
    name: Meter readings
    entities:
      - sensor.power_consumption_low
      - sensor.power_consumption_normal
      - sensor.power_production_low
      - sensor.power_production_normal
      - sensor.gas_consumption
```

Optional configuration example for ser2net:
```sh
# 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
```

[HASSbian](/getting-started/installation-raspberry-pi-image/) users have to give dialout permission to the user `homeassistant`:

```
$ sudo usermod -a -G dialout homeassistant
```

and after that you need to reboot!

```
$ sudo reboot
```
