:description: Instructions for setting up DSMR Meter component in ESPHome.

|
||
Component/Hub
|
||
-------------
|
||
|
||
The DSMR component connects to Dutch Smart Meters which comply to DSMR (Dutch Smart Meter
|
||
Requirements), also known as ‘Slimme meter’ or ‘P1 port’.
|
||
|
||
This integration supports plain non encrypted telegrams and also encrypted as used in Luxembourg.
|
||
In case your equipment has encryption you must get a 32 character long encryption key from your energy company.
|
||
|
||
This component is passive, it does not transmit any data to your equipment, the equipment always transmits
|
||
data which this component decodes and updates the configured sensors at the pace the data is received.
|
||
|
||
- For official information about DSMR refer to: `DSMR Document <https://www.netbeheernederland.nl/dossiers/slimme-meter-15>`__
|
||
- For official information about the P1 port refer to: `P1 Companion Standard <https://www.netbeheernederland.nl/_upload/Files/Slimme_meter_15_a727fce1f1.pdf>`__

|
||
|

|
||
Configuration variables:
|
||
|
||
- **decryption_key** (*Optional*, string, :ref:`templatable <config-templatable>`, 32 characters, case insensitive):
|
||
The key to decrypt the telegrams. Used in Lux only.
|
||
- **gas_mbus_id** (*Optional*, integer): The id of the gas meter. Defaults to ``1``.
|
||
- **crc_check** (*Optional*, boolean): Specifies if the CRC check must be done. This is required to be set to false for
|
||
older DSMR versions as they do not provide a CRC. Defaults to ``true``.
|
||
- **max_telegram_length** (*Optional*, integer): The size of the buffer used for reading DSMR telegrams. Increase
|
||
if you are reading from a smart meter that sends large telegrams. Defaults to ``1500``.
|
||
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the UART hub.
|
||
- **request_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The pin that can be used for controlling
|
||
the P1 port's Data Request pin. Defaults to not using a Data Request pin.
|
||
See :ref:`Using the P1 Data Request pin <sensor-dsmr-request_pin>`.
|
||
- **request_interval** (*Optional*, :ref:`config-time`): The minimum time between two telegram readings.
|
||
Defaults to ``0ms``, meaning that the pace at which the smart meter sends its data determines the update frequency.
|
||
This works best in combination with a ``request_pin``, but this option will work without one too.
|
||
- **receive_timeout** (*Optional*, :ref:`config-time`): The timeout on incoming data while reading a telegram.
|
||
When no new data arrive within the given timeout, the device will consider the current telegram a loss and
|
||
starts looking for the header of the next telegram. Defaults to ``200ms``.
|
||
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID of the DSMR if you have multiple components.

|

.. _sensor-dsmr-request_pin:

||
|
||
P1 Data Request pin
|
||
-------------------
|
||
|
||
From the P1 companion guide: The P1 port is activated (start sending data) by setting "Data Request" line high
|
||
(to +5V). While receiving data, the requesting OSM must keep the "Data Request" line activated (set to +5V).
|
||
To stop receiving data OSM needs to drop "Data Request" line (set it to "high impedance" mode). Data transfer
|
||
will stop immediately in such case.
|
||
|
||
**Advantages when using a request pin:**
|
||
|
||
- After reading a telegram, the dsmr component will stop the data transfer until the telegram has been
|
||
fully processed. This separates retrieving and processing data and can thus be seen as a form of
|
||
hardware flow control.
|
||
- The interval at which sensor readings must be updated can be controlled cleanly by only starting a data
|
||
transfer when needed. This configuration option ``request_interval`` can be used to define this interval.
|
||
|
||
**Required hardware support**
|
||
|
||
Many DSMR reader circuits link the +5V pin of the P1 port directly to its Data Request pin. Doing this will
|
||
make the smart meter send telegrams at a pace as defined by the smart meter firmware. For example many
|
||
DSMR v5 meters will send a telegram every second.
|
||
*Circuits that use this type of wiring cannot make use of the* ``request_pin`` *option.*
|
||
|
||
However, when a circuit is used that allows switching the Data Request pin between +5V and high impedance
|
||
mode from a GPIO, then this GPIO can be configured as the ``request_pin``.
|
||
|
||
Best results have been achieved by using an optocoupler circuit to handle the switching. Direct GPIO output
|
||
or a transistor-based circuit are not feasible options. Here's an example circuit design:
|
||
|
||
.. figure:: images/dsmr-request-pin-circuit-example.png
|
||
|
||
.. _sensor-dsmr-improving_reader_results:
|
||
|
||
Improving reader results
|
||
------------------------
|
||
|
||
When telegrams are sometimes missed or when you get a lot of CRC errors, then you might have to do some
|
||
changes to get better reader results.
|
||
|
||
It is recommended to set the ``rx_buffer_size`` option of the UART bus to at least the maximum telegram size,
|
||
which defaults to 1500 bytes. The default UART read buffer is quite small an can easily overflow, causing
|
||
bytes of data getting lost.
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Example configuration
|
||
uart:
|
||
pin: D7
|
||
baud_rate: 115200
|
||
rx_buffer_size: 1700
|
||
|
||
dsmr:
|
||
max_telegram_length: 1700
|
||
|
||
It's best when a hardware UART is used for reading the P1 data. Whether or not hardware UART is used can
|
||
be checked in the config dump that you get when connecting to the API logger. Example logging output:
|
||
|
||
.. code-block:: text

|
||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
||
When using an ESP8266, then GPIO13 (e.g. pin D7 on a D1 Mini) can be used for hardware RX. However, to
|
||
actually make it work, serial logging must be disabled to keep the hardware UART available for D7.
|
||
|
||
.. code-block:: yaml
|
||
|
||
# Example configuration for ESP8266
|
||

|
||

|
||

|
||
|
||
