Energy!

Enjoy your Omnik solar production at the Home Assistants new Enery dashboard with the latest version of Omnik Data Logger. An update was needed to make the MQTT energy sensors compliant with the new Energy feature. The Energy feature was released with the latest version of Home Assistant.

As you can see I just started monioring my self. For Solar Production you can use the Energy today or the Energy total entity. The Energy today sensor is more accurate for this aim. If you have integrated DSMR (Dutch Smart Meter R.) as well you can also use these entities to add Grid consumption and Return to grid.

DSMR sources

If you want to add the consumtion of specific devices and you have entities for those devices, you could add those entities as well.

Enjoy!

New Docker builds for Omnik Data Logger

New Docker builds are available for Omnik Datalogger. Docker containers are ideal when you are not using Home Assistant or the Home Assistant community store (HACS). Docker builds can be easily deployed on multi platforms. Currently the following architectures are supported:

  • linux/amd64
  • linux/arm64
  • linux/arm/v7
  • linux/arm/v6

If you need a different architecture, please let me know. Docker and pip builds and are now automatically generated by Github actions when a new release is published.

See https://github.com/jbouwh/omnikdatalogger/wiki/Install-using-docker for more information. If you previous used Docker containers for this project, then make sure your configuration is correct. The default location for config files in the containers has been change to the /config folder.

Omnik api offline

If you were a happy user of omnik portal, you may have been noticed about Omnik bankruptcy throught the communications by Solarman. Solarman managed the infrastructure for Omnik all the time. Your omnik inverter is still logging its data the same way it did for years. The complete portal is still accessable from https://www.solarmanpv.com/portal. Here you can still use the credentials you used at omnikportal.com

Omnikdatalogger ‘omnikportal’ client removed from software.

Since the Omnikportal API is down too, you will need an alternative. Omnikdatalogger also has a solarmanpv client that can get your inverters logged data. See more about the configuration at the Omnikdatalogger WIKI pages or the Dutch WIKI pages on this site. Solarman has indicated they will continue to offer this as a free (trial) service till the end of 2021. With omnikdatalogger you also can get your inverters data using the tcpclient or localproxy client module.

Ready for production

Omnikdatalogger has been stabilized and updated to run stable with HACS and docker now. There were some problems during restarts, especially with HACS that now have been solved. Some parts of the DSMR integration did not shutdown properly. That is all solved now. I am curious to know how what your experience is with omnikdatalogger. Let me know using the comments.

Wiki udated

The omnikdatalogger wikipages have been updated and are completed now.

Docker support for Omnik data logger

Omnik data logger now also can be installed in docker container. This makes it easy to integrate in a docker based environment. This is an alternative to using AppDaemon with HACS.

Install the docker image

Use the command docker pull jbouwh/omnikdatalogger to pull the latest image.

To build image your self from git:

git clone https://github.com/jbouwh/omnikdatalogger
cd omnikdatalogger/
docker build --tag jbouwh/omnikdatalogger:latest .

Running the docker image

In the folowing example assumed is that the config file outside the container is at /home/pi/.omnik/config.yaml (user pi). In the docker image the user is omnik and the default location for the configuration inside the container is at /config/config.yaml

The -p option is only needed when the localproxy client is used with the tcp_proxy plugin.

Use --device option to give direct access to a DSMR compliant USB monitoring cable. Alternatively use ser2net.

Run image in the background using the following command:

docker run -d -v /home/pi/.omnik/config.yaml:/config/config.yaml -p 10004:10004 --device /dev/ttyUSB0 --name omnikdatalogger jbouwh/omnikdatalogger:latest

Omnik data logger DSMR P1 support

With the new brand new release of Omnik data logger I have included support for the Dutch Smart Meter Requirements compliant Electricity meter. With a simple FTDI P1 to USB serial adapter Omnik datalogger now also publish your smart meter data including gas. With PVoutput this means we can also upload the consumed energy and calculate the netto energy used/delivered.

The P1 adapter can be either connected directly to your device or using TCP. I used ser2net to be able to connect multiple sessions to my P1 meter. To make this possible you will need at least ser2net v3.5. I have used a docker container installing ser2net (jsurf/rpi-ser2net:buster). Adding the max-connections option will enable me to do some debugging and in the mean will logging my data.

3333:raw:600:/dev/ttyUSB0:115200 NONE 1STOPBIT 8DATABITS -XONXOFF RTSCTS max-connections=3

/etc/ser2net.conf

If you publish your smart meter to Home Assistant this can replace the native dsmr integration include with Home Assistant. Over MQTT auto discovery Home Assistant will discover automatically. In the config file you can rename the entities for your smart meter. Addition direct use, direct consumption and the real calculated consumption data will be published over MQTT and InfluxDB.

HACS Default

Omnik data logger now has been added to the default store. This means there is no need to add a custom repository any more. You can find Omnik data logger at the Automation section.

Make sure you have installed the AppDaemon Add-on from the official Home Assistant Add-on store.

TCPclient tested and working now

Thanks to Han Lubach the tcpclient could be tested and corrected. It seems this client, based on Wouter van der Zwan’s logger is now usable with Omnik data logger as well.

Omnik data logger news update

PIP support for omnikdatalogger and omnikdatalogerproxy

Omnikdatalogger can now be installed using PIP:

sudo pip3 install omnikdatalogger

To install only omnikdataloggerproxy use sudo pip3 install omnikdataloggerproxy

HACS default support

Omnikdatalogger could be installed as a custom repository within HACS. A request to include Omnik data logger in the default repository was requested and approved.
