DSMR binding

Jump to bottom
Martin van Wingerden edited this page Oct 23, 2016 · 8 revisions

Introduction

The DSMR-binding is targeted for Dutch users having a smart meter ('Slimme meter' in dutch). Data of Dutch smart meters can be obtained via the P1-port. When connecting this port from a serial port the data can be read out.

This binding reads the P1-port of the Dutch Smart Meters that comply to NTA8130, DSMR v2.1, DSMR v2.2, DSMR v3.0, DSMR v4.0 or DSMR v4.04.

If you are not living in the Netherlands but do want to read a meter please have look at the IEC-62056-21 Meter Binding.

Global Binding Configuration

To enable the binding please include the following configuration in openhab.cfg

######################## DSMR Binding ###########################

# Port of the DSMR port (mandatory, e.g. /dev/ttyUSB0)
dsmr:port=/dev/ttyUSB1

# Configuration of additionel meters (channel 0 is used for the main
# electricity meter)
#dsmr:gas.channel=1
#dsmr:water.channel=2
#dsmr:heating.channel=3
#dsmr:cooling.channel=4
#dsmr:generic.channel=5
#dsmr:slaveelectricity.channel=6

The channel of the additional meters correspond to the M-Bus channel of the smart meter that the additional meter is connected to. Since the main electricity meter is always at channel 0, configuration of this meter is not necessary (and not supported).

Differences between DSMR versions

The serial port settings for DSMR v4 and up (115200 8n1) differ from NTA8130, v2.1, v2.2 and v3.0 (9600 7e1). The DSMR binding will automatically detect the applicable serial port settings.

Logging

Use the following setting in logback.xml to increase verbosity of the logging

<logger name="org.openhab.binding.dsmr" level="DEBUG"/>

Generic Item Binding Configuration

In order to bind an item to the DSMR binding, you need to provide configuration settings. The syntax for the DSMR binding configuration string is:

dsmr="[dsmr item id]"

The following table shows the full list of available dsmr values:

1 This item isn't part of any specification however, the ITRON ACE4000 GTMM Mk3 does use this value. 2 Gas values for DSMR v3.0 are available in a list of max. 10 entries. The binding assumes the first value is the most recent (and thus available in gValue)

Examples

``` Number P1_Actual_Delivery "Actual usage [%.3f kW]" {dsmr="eActualDelivery"} Number P1_Meter_DeliveryLow "Meterstand reading low tariff [%.3f kWh]" {dsmr="eDeliveryTariff1"} Number P1_Meter_DeliveryNormal "Meter reading normal tariff[%.3f kWh]" {dsmr="eDeliveryTariff2"} ```

Remarks

  • A meter that conforms to DSMR v4 or higher includes a CRC on the complete message. The binding does not check the CRC yet.
