A sensor platform for Belgian, Dutch, Luxembourg and Swedish Smart Meters which comply to DSMR (Dutch Smart Meter Requirements), also known as ‘Slimme meter’ or ‘P1 poort’. Swedish meters with a ‘HAN port’ are not supported by this integration.
- Currently support DSMR V2.2, V3, V4, V5, Belgian V5 variant, Luxembourg V5 variant (Smarty) and the Swedish V5 variant through the dsmr_parser module by Nigel Dokter.

- For official information about the P1 port refer to: P1 Companion Standard
- For unofficial hardware connection examples refer to: Domoticx
- For official information about the Swedish variant refer to: Swedish specification.

To configure options for DSMR integration go to Configuration >> Integrations and press Options on the DSMR card.
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.
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
- Ziv E0058 ESMR5
Connection can be done directly to the meter via a USB to serial connector, or through a serial to network proxy
Docker users have to allow Docker access to the USB to serial converter 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 ghcr.io/home-assistant/home-assistant

Adding DSMR Slimme Meter to your Home Assistant instance can be done via the user interface, by using this My button:
If the above My button doesn’t work, you can also perform the following steps manually:

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.
Smart meters in Belgium, Luxembourg and Sweden provided telegrams with largely the same contents.
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.
