A sensor platform for Dutch Smart Meters which comply to DSMR (Dutch Smart Meter Requirements), also known as 'Slimme meter' or 'P1 poort'.
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, V5 Belgian and V5 Smarty through the [dsmr_parser](https://github.com/ndokter/dsmr_parser) module by Nigel Dokter.
- Currently support DSMR V2.2, V3, V4, V5, Belgian V5 variant, Luxembourg V5 variant (Smarty) and the Swedish V5 variant through the [dsmr_parser](https://github.com/ndokter/dsmr_parser) module by Nigel Dokter.

### Configuration
- For Belgian meters, choose DSMR version `5B`
- For Dutch meters, choose DSMR version `2.2`, `4`, or `5`
- For Luxembourg meters, choose DSMR version `5L`
- For Swedish meters, choose DSMR version `5S`
### Options
To configure options for DSMR integration go to **Configuration** >> **Integrations** and press **Options** on the DSMR card.
#### Time between updates
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.
<div class='note warning'>
Reducing the default time between updates will increase the amount of events generated and can potentially flood the system with events.

### Connecting to the meter
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 seriacl converter by adding `--device /dev/ttyUSB21:/dev/ttyUSB21` to the run command:

### Technical overview
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.
