# DSMR Binding

The DSMR-binding is targeted towards Dutch, Belgium and Luxembourger users having a smart meter (Dutch: 'Slimme meter'). Data of Dutch/Belgium/Luxembourg 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:

  • Dutch Smart Meters that comply to NTA8130, DSMR v2.1, DSMR v2.2, DSMR v3.0, DSMR v4.0, DSMR v4.04, and DSMR 5.0.
  • Belgium Smart Meters that comply to e-MUCS v1.0.
  • Luxembourg’s electricity meter "Smarty" that comply to V1.0.

Although DSMR v4.2 is not an official specification, the binding has support for this version.

If you are not living in the Netherlands/Belgium/Luxembourg but do want to read a meter please have look at the SmartMeter Binding. Because the Dutch Meter standard is based on the IEC-62056-21 standard it might be desirable to build support for other country metering systems based on that standard in this binding.

# Serial Port Configuration

The P1-port is a serial port. To configure the serial port within openHAB see the general documentation about serial port configuration.

# Supported Things

# dsmrBridge (The Netherlands/Belgium)

dsmrBridge: This is the device that communicated between the binding (serial) and its internal meters. You always have to have a 'Dutch/Belgium Smart Meter'-bridge. The bridge contains the serial port configuration. Specific meters are bound via the bridge to the smart meter. A smart meter consists typically out of minimal 2 meters. A generic meter and the electricity meter. Each meter is bound to the DSMR protocol the physical meter supports. For each meter it is possible to set a refresh rate at which the status is updated. The physical meter might update with a high frequency per second, while it is desired to have only values per minute.

The Belgium e-MUCS protocol is an extension to the DSMR standard. Belgium meters have emucs in the thing name. Due to it similarities the bridge for Belgium meters is also a dsmrBridge.

# smartyBridge (Luxembourg)

smartyBridge: This is the device that communicated between the binding (serial) and its internal meters. You always have to have a 'Smarty Smart Meter'-bridge. The bridge contains the serial port configuration.

# Discovery

The dsmrBridge and meters can be discovered via the discovery process. The smartyBridge can be discovered. Because the smartyBridge requires a decryption key. You need to set the decryption key when the bridge is added. After the decryption key is set a new discovery can be started to discover the meter.

If a bridge is manually configured it is possible to auto detect available meters.

# Configuration

The configuration for the dsmrBridge consists of the following parameters:

Parameter Description
serialPort The serial port where the P1-port is connected to (e.g. Linux: /dev/ttyUSB1, Windows: COM2) (mandatory)
receivedTimeout The time out period in which messages are expected to arrive, default is 120 seconds
baudrate Baudrate when no auto detect. valid values: 4800, 9600, 19200, 38400, 57600, 115200
databits Data bits when no auto detect. valid values: 5, 6, 7, 8
parity Parity when no auto detect. valid values: E(ven), N(one), O(dd)
stopbits Stop bits when no auto detect. valid values: 1, 1.5, 2

The configuration for the smartyBridge consists of the following parameters:

Parameter Description
serialPort The serial port where the P1-port is connected to (e.g. Linux: /dev/ttyUSB1, Windows: COM2) (mandatory)
decryptionKey The meter specific decryption key (mandatory)
receivedTimeout The time out period in which messages are expected to arrive, default is 120 seconds

Note: The manual configuration is only needed if the DSMR-device requires non DSMR-standard Serial Port parameters (i.e. something different then 115200 8N1 or 9600 7E1)

# Troubleshooting

If there are unexpected configuration issues. For example a meter could not be found or not all channels expected are available. Than run the discovery process and look into the log file. There are extra checks that can give more information about what might be wrong.

# Meters

The information in this paragraph in necessary if you choose to configure the meters manually in a .things file.

note 2. The power failure log has a dynamic number of entries starting at 0. So emeter_power_failure_log_timestamp0, emeter_power_failure_log_duration0 refers to the first entry, emeter_power_failure_log_timestamp1, emeter_power_failure_log_duration1 refers to the second entry, etc.

Channel identifier: dsmr:<ThingTypeID>:<bridge id>:<id>:<channel type id>

  • ThingTypeID. See table with supported meters
  • BridgeID. The configured id for the bridge
  • id. The configured id for the ThingType you want to address
  • channel type id. The channel type id

The following configuration must to be added to an item configuration file. E.g. things/dsmr.items

ItemType <name> "<description>" (<Group>) {channel="<Channel identifier>"}

Examples

Number:Energy MeterDeliveryTariff0 "Total electricity delivered to the resident during low tariff period [%.3f kWh]" {channel="dsmr:electricity_v5_0:mysmartmeter:electricityV5:emeter_delivery_tariff1}

# Full configuration example

    Things:

# Determine M-Bus channel

By manually trigger the discovery process, you can use the logging to find out a M-Bus channel. Look for the following logfile line: <Timestamp> [INFO ] [<class>] - New compatible meter: [Meter type: M3_V5_0, channel: 1, Meter type: ELECTRICITY_V5, channel: 0]

Here you find the ThingTypeID (it is stated only in capitals) and the M-Bus channel. The above example would lead to the following Thing definition

Bridge definition {
    Things:
        m3_v5_0 mygasmeter [channel=1]
        electricity_v5 [channel=0]
}
