Omnik Data Logger

omnik-data-logger

WORK IN PROGRESS ...

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.

Installation

Install using the following command:

$ pip install --user git+https://github.com/paprins/omnik-data-logger.git

Help

$ omnik-logger -h
usage: omnik-logger [-h] [--config FILE] [-d]

optional arguments:
  -h, --help     show this help message and exit
  --config FILE  Path to configuration file (default: ~/.omnik/config.ini)
  -d, --debug    Debug mode

Configuration

Example configuration

[omnikportal]
username = [e-mail]
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

Run

Just run omnik-logger ... that's it ... for now.

You need to schedule this

Tickets

• Create client that connects to omnik-portal and fetches data.
• Add CLI interface.
• Add (flexible) support for plugins that can process this data.
• Add Dockerfile to build a docker image + include script that triggers omnik-logger every X minutes.
• Add docker-compose.yml to combine omnik-data-logger with, for example, influxdb container.
• Combine omnik data with P1 data to enrich PVOutput data

Plugins

Working on a couple of plugins to customize processing of the omnik-portal data:

• pvoutput ~ write data to PVOutput
• influxdb ~ write data to a InfluxDB time series database
• ...
