After trying to use Home Assistant for some time I have decided to switch to openHAB for a few reasons, charts, interface and a very active development. I thought I start very simple with visualizing current temperature and a temperature chart of my Netatmo sensor. Installing openHAB was easy and I have also managed to connect the Netatmo with the help of Paper UI. Now to my question, how to I visualize the current temperature, store time series data and show this in a nice looking chart? In the future I would like to add more sensors to the same chart. Preferable I would like to use graphical interfaces as much as possible and I also like the appearance of Habpanel.
