# dsmr2mqtt
This utility reads the telegrams from your DSMR-compatible smart meter and sends it
to a MQTT broker. I made use of [dsmr-p1-parser](https://github.com/lvzon/dsmr-p1-parser) and [libmosquitto](https://mosquitto.org/man/libmosquitto-3.html).
I wrote this so I would be able to plug my smart meter into my OpenWRT router with a
prefabricated cable (I used this one: https://www.sossolutions.nl/slimme-meter-kabel).
I used the MQTT topic definitions of [dsmr-reader](https://github.com/dennissiemensma/dsmr-reader).
If you want to use other definitions, you can change the the #defines at the beginning of the *dsmr2mqtt.c* file.
## Compiling
### Debian/Ubuntu
First make sure you have git installed and the necessary library.
```
# apt install git libmosquitto-dev
```
Then get the source code and use the command make to build the dsmr2mqtt executable:
```
$ cd [whatever build dir]
$ git clone https://github.com/terual/dsmr2mqtt
$ cd dsmr2mqtt
$ make
$ ./dsmr2mqtt
```
### Cross-compiling for OpenWRT
To compile this for OpenWRT, use the following [guide](https://openwrt.org/docs/guide-developer/using_the_sdk),
place the Makefile.openwrt in a seperate dsmr2mqtt package folder, and rename it to Makefile.
## Using the tool
```
Usage: dsmr2mqtt [-d ] [-m ] [-p ]
-d Serial device for DSMR device (default is /dev/ttyUSB0)
-m Host name for MQTT broker (default is localhost)
-p Host name for MQTT broker port (default is 1883)
```
