Tried this and it works fine. The simple way to show temperatures is this:

The more complicated but more fun way is this:

I have tried to use Grafana before but had problems with headers etc. Thanks to this module most problems are solved.

I get the data from my z Wave sensor http://aeotec.com/z-wave-sensor. This is connected to a raspberry running home assistant. On another raspberry I use influxdb and grafana. Home assistant is sending influx data to this PI. On the thirs Raspberry i run Magic mirror and the result is displayed. The only issue is that in dark light you can see the border and background in the graph even if it is set to black. Maybe this is just a feuture of the mm and the screen.

I also tried to use the same module to display if the door is locked or unlocked. I also get the data from home assistant.
