Graph module

feedparakeet

@planet4 , what I did is:

cd /usr/share/grafana/public/css
find . -type f -exec sed -i.bak "s/141414/000000/g" {} \;

This command creates a .bak files with the original content of each modified file in case you would like to turn everything back.
Then, I enabled General-Dimentions-Transparent for each graph. And enabled General-Toggles-Hide controls for a dashboard.
My grafana’s header automatically goes away in few minutes if I don’t touch anything or move mouse. But even if I don’t see grafana’s grey header line, I can still see grafana’s orange-colored label.
Does your grafana’s grey header goes away if you don’t touch anything for 5 minutes? If not, then you should update to a new version. This feature is quite new.

I wrote a little blog post, to describe how to use Influxdb and Grafana to build a weather chart. It’s available here.

@SvenSommer Very nice! I will try this as soon as I have reinstalled my old RPI. I have used the database to get info from home assistant so I can display graphs from my z wave sensor. However I am just wondering how it can display the graph as Grafana have a login page with password. Do I have to do something special in order to make this work.

@planet4 The tutorial explaines how to enable authentication via http to access influxdb without login.

You’re changing parts of the configuration file /etc/influxdb/influxdb.conf

[http]
enabled = true bind-address = ":8086" # change to a specific interface if needed 
auth-enabled = true # will enforce authentication
...

To access your Grafana graphs remotely, you can use the share option to get a public accessible link. The same url uses MMM-GrafanaChart to show the graph on the mirror.

Let me know if you ran in any problems…

@planet4 if you want to see Grafana’s charts without login\password, you should turn on anonymous access.

Edit /etc/grafana/grafana.ini

[auth.anonymous]
enabled = true
org_name = FeedParakeet
org_role = Viewer

Then you should go to Grafana’s GUI - Profile settings and set the “Name” field equal to the “org_name” value.

Your graphs will be visible to anyone. But it wil be impossible to change anything without loging in.

@feedparakeet
I think there is even a better way. You can share each panel individually.

@SvenSommer wow, it works even easier, thanks

Ok, Almost there. The gauge shows perfect on my mirror. Influx and Grafana is setup. I get the data from this sensor. http://aeotec.com/z-wave-sensor.

However I still get the grey/brown background on the mirror. Tried to set it to transperant and also modified the css files as described in a post before here. It is just not black. Any smart ideas?

@planet4 I’m glad to hear, everything worked out as expected.

If you want to do me a favor. Please let others know in the module teaser thread, you were able to use the module. So maybe other lose their fear. ;)
I had a look at changing the background color by inverting the colors of the “white” theme. Didn’t worked out, cause it’s no real white neither.
