    I’m logging room temperature and humidity to a csv file. How would I go about using the data to graph it to my mirror?

      I’m using a bunch of graph already… why not using Grafana to record the data and the iFrame module to display them in your MM ?

        That’s a good idea actually. I don’t know what grafana is, will look into it. I might just use the temperature logging python code I have and add a graphing portion to it as well and then use the iframe module to display the graph. Sounds feasible on paper.

          @PointPubMedia, thanks, Grafana looks good. I have it installed now to graph server’s cpu, network, e.t.c… Could you tell me please what do you use as a data source for Grafana to create custom graphs? I want to create bitcoin-usd graph, but I don’t know how can I put a data into Grafana.
          And how do use put Grafana’s graph into iFrame module? Are there any tricks you can share?

            @feedparakeet I disable the authentication in Grafana so I can use direct link to a graph without a username/password!

            In grafana, you can “export” a graph and it will give you a direct URL that you can use directly in an iFrame!

            For datasource, currently I’m using a module in my home automation that already send data to grafana!

            I need to work later on some unix script to send data directly in grafana!

              @PointPubMedia Thanks! It worked!
              Final setup is: php scripts which grab info from fixer.io (eur + usd) and btc-e.com (bitcoin), put them to InfluxDB and display with Grafana. Works like a charm!
              Here is a screenshot from my MM. Looks beautiful in general. But still, few minor things to work on.

                @qistoph, thank you, I really appreciate your response. It took me few weeks to understand how do graphs work and get what I need. Finally I did it with Grafana + InfluxDB + PHP scripts. Now I understand that each graph is very special and you need quite a few options to get it work like you want. So, Grafana is the solution for what I was looking for. Don’t think it will be easy to create a universal graph module to satisfy all my needs, like I thought it before. Thanks anyway!

                  @d3r It is absolutely possible with Grafana + iFrame module and a bit of magic lol

                    @feedparakeet How did you get grafana to use all black background?

                      @jalmaas I did it with a very rude way. I have changed all 141414 color to 000000 for background settings in /usr/share/grafana/public/css/grafana.dark.* files
                      Same way you can remove everything else, like Grafana logo.
