Graph module

planet4

@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.
