MQTT Dash and Hassio
Hi,

I've been trying out PAI addon for HASSIO: it worked right out the box!

However, I'm trying to get the MQTT Dashboard working on Android without success.
I've added `MQTT_DASH_PUBLISH: true` to my config but got the following error in the logs:
```
WARNING  - PAI.paradox.interfaces.mqtt.basic - MQTT DASH Template not found: /etc/pai/mqtt_dash.txt
```

Am I supposed to add this template or should it already be in the container ?

I'm sorry If I missed any info in the wiki, I couldn't find anything relevant.
