This is a Python3 based PV data logger with plugin support, specifically build for the Omniksol-5k-TL2. This datalogger uses the omnikportal to fetch data pushed by the inverter. I tried using the inverter directly, but the firmware is very buggy: it either spontanious reboots, hangs or returns seemingly random data.
Install using the following command:
$ pip install omnik-data-logger
usage: omnik-logger [-h] [--config FILE] [--every EVERY] [-d]
optional arguments:
-h, --help show this help message and exit
--config FILE path to configuration file
--every EVERY execute every n seconds
-d, --debug debug mode
Example configuration
This data logger needs a configuration file. By default, it look for a config file called ~/.omnik/config.ini
. You can override this path by using the --config
parameter.
[default]
timezone = Europe/Amsterdam
[omnikportal]
username = john.doe@example.com
password = S3cret!
[plugins]
output=pvoutput
[pvoutput]
api_key = <YOUR API KEY>
sys_id = <YOUR SYSTEM ID>
use_temperature = true
[openweathermap]
api_key = <YOUR API KEY>
endpoint = api.openweathermap.org
lon = 4.2232362
lat = 51.8819023
units = metric
PS: openweathermap
is currently only used when use_temperature = true
.
Just run omnik-logger
... that's it ... for now.
You've got your default options to schedule this logger, but I included a systemd
service file to run this as a service on Linux.
PS: I'm using
Ubuntu 18.04 LTS
First, install this thing (~ using Python 3 !!!)
If you don't have
Python3.x
installed, do that first (~ don't forget to installpython3-pip
as well)
$ pip3 install omnik-data-logger
# check if properly installed
$ omnik-logger -h
usage: omnik-logger [-h] [--config FILE] [--every EVERY] [-d]
optional arguments:
-h, --help show this help message and exit
--config FILE Path to configuration file
--every EVERY Execute every n seconds
-d, --debug Debug mode
Copy scripts/omnik-data-logger.service
to /lib/systemd/system/omnik-data-logger.service
Next, enable and start service:
$ systemd enable omnik-data-logger
Created symlink /etc/systemd/system/multi-user.target.wants/omnik-data-logger.service → /lib/systemd/system/omnik-data-logger.service.
$ systemd start omnik-data-logger
Check if omnik-data-logger.service
is running correctly:
$ systemd status omnik-data-logger

Working on a couple of plugins to customize processing of the omnik-portal data:
pvoutput
~ write data to PVOutputinfluxdb
~ write data to a InfluxDB time series database (WORK IN PROGRESS)- ...
