Create a dashboard based on grafana running on raspberry pi3

Decided to scrap all the previous attempt for a dashboard for solar power generation graphs and going for a simpler version running grafana.

The goal for this hackweek is to install opensuse tumbleweed on existing raspberry pi3 (the previous installation, based on raspbian is shot, anyway) and prepare a python script to collect necessary data: - Solar panels array A/B voltage - Current to battery - Calculated power in Watts - Consumed AC current from smart plug device - AC Voltage output - Battery charge capacity - System temperature
